10 Settings menu overview The setting menu is build in a way, which makes it easy to user. Ventilation: Here are settings made concerning the ventilation of the house. Domestic hot water production: Here are settings made concerning the domestic hot water. Central heating: Here are settings made concerning the central heating of the house. General settings: Here are settings made concerning both ventilation, domestic hot water, central heating and service settings. Information: Here you find eventlog together with an overview of actual settings for the unit. Emergency stop ventilation: It is not supposed to shut down the ventilation, because you can get problems with condensed water in the ducts. But in emergency situation, ect. a fire in a nearby factory where you are asked to go inside you house and shut doors and windows and shut down your ventilation system. In those situations it is possible to shut down the ventilation via the emergency stop ventilation. User and installer rights In the setting menu both user, installer and factory settings are shown. Settings without any lock, can be set by all Settings with a white lock can only be set by installers Settings with a red lock can only be set by Nilan 10

11 Compact P / Compact P Polar GEO (English) BY NILAN The reason why some settings is locked for the user, is because to change them you need some knowledge about how the unit works, and if they are set wrongly the unit does not work properly and can be damaged. How to unlock the installer settings It is possible to unlock the settings for installers, by touching the white lock. It does not matter, where in the settings you touch a white lock, a pop-up picture appears, where you can inset the installer password. A keyboard appear, where the installer can insert the password. After that all white locks is unlocked., and the installer can make changes in the settings. The locks can be locked again by touching a white lock. If you do not lock the locks again, after a while they will lock themselves automatic. 11

12 Startup Set language Default language in the control system is Danish. Other languages can be selected in the touch-panel. General settings Language Change language Select a language by touching the "Change language" key. Set date and time It is important to set the date and time correctly., especially if you wish to log data from the unit, and in case of error it makes it easier to locate the error. The time is also shown under information on the display. General settings Date and time Set date Set the date by pressing "Set date" and scrolling the wheel. Set time Set the time by pressing "Set time" and scrolling the wheel. 12

13 Compact P / Compact P Polar GEO (English) BY NILAN Turning the unit on and off When power is connected, light will appear in the control panel, but the unit will be turned off. This is to ensure, that no failures happens etc. there is not yet water in the water tank and the unit starts to heat up hot water. To allow the unit to run, it must be activated in the service menu under General settings. ATTENTION Before working on electrical installations, the power supply must be turned off ATTENTION It is important that the ventilation section is not turned off for lengthy periods, as this could cause condensation problems in the duct system. General settings Service System power On / Off Off The unit is turned of at the factory to avoid errors occuring when power is connected. The installer must start the unit here. The installer also has a facility for turning off the whole unit, for instance during a service inspection. 13

14 Ventilation Filter settings The filter alarm has a timer which is set at the factory to give 90 days between filter changes. If it is wished to connect pressure-controlled filter change warning, pressure sensors can be connected via a digital input, and the change is made in the filter menu under Warning filter change, by selecting Digital. It is also possible to deselect the filter alarm. This is typically done in flats, where the caretaker changes the filter according to a calender and does not want the residents ringing up because of a filter alarm just because he or she is a day or two late. Supply air filters and extract air filters are set separately. The unit is supplied from the factory with a standard G4 filter, but a F7 pollen filter can also be purchased for the outdoor air inlet. The service life of the two types of filter differs. Ventilation Filter settings Set ventilation on pause Description On / Off Off Before the unit is opened for changing the filter, the ventilation must be turned off. If you forget to turn the ventilation on again, it will restart automatically after 2 hours. Outdoor air filter Filter change warning Timer / Digital / Disable Timer Timer: Counts the days to next filter change. Digital: Receives signal from e.g. a filter monitor via a pressure sensor. None: No warning when the filter needs changing. Days between filter change days 90 days Number of days between filter changes can be set as required. It is important that filters are clean, to give optimum operation and low power consumption. Dirty filters reduce the production of domestic hot water. Days to next filter change Shows how many days remain to the next filter change. Reset timer Press to reset timer. Extract air filter The same setting options as for the outdoor air filter. 14

15 Compact P / Compact P Polar GEO (English) BY NILAN Operating mode It is possible to provide the unit with an input which determines whether it will operate in Auto, Heating or Cooling. Ventilation Operating mode Auto / Heating / Cooling Auto Auto: The unit operates in according with the set values. Heating: The unit operates in accordance with the set values, but is not set to perform cooling. Active cooling has been blocked and the bypass damper will not open. Cooling: The unit operates in accordance with the set values, but is not set to perform heating. Active heating and the after heating element have been blocked. With this setting the unit can perform cooling in winter operation under the correct conditions. The functions Heating and Cooling override the weekly schedule, and can be used in situations such as the following: Heating A weekly schedule has been made in which the room temperature is lowered between 8.00 and during the day, when the residents are at work or school. During the autumn half-term they no longer wish to lower the daytime temperature as they are at home that week. Instead of cancelling the weekly schedule, this can be overridden by setting the unit to heating mode. The unit now operates in accordance with the desired room temperature, which can be set on the front of the touch-panel. Cooling A large modern house with extensive south-facing windows can start having overheating problems as early as March/April, if the sun is shining form a cloudless sky. As the outdoor temperature is maybe only 8 C, the unit will be running in winter mode, with a setting which prevent it perform cooling. This limitation can be overridden by setting the unit to cooling mode. The unit will then first attempt to cool the indoor air by means of the bypass. If the bypass provides insufficient cooling, active cooling via the heat pump will start up. ATTENTION The system will automatically change to Auto on the next change in the weekly schedule, is such is programmed. 15

16 Setting the fan speeds You can set the four fan speed level in the range from 20% to 100%. It is possible to set supply air and extract air individually, which is a big advantage by balancing the ventilation system. Ventilation Fan speed settings Fan speed level 1 Fan speed level 2 Fan speed level 3 Fan speed level 4 Description % supply air / extract air 25 % / 27 % supply air / extract air Level 1 is usually used for "Low humidity" and "Low ventilation at low outdoor temperature" functions % supply air / extract air 45 % / 48 % supply air / extract air Level 2 is usually used for basic ventilation % supply air / extract air 65 % / 70 % supply air / extract air Level 3 is usually used for the "High humidity" function and "Guest level" % supply air / extract air 90 % / 100 % supply air / extract air Level 4 is usually use for cooker hood, "High ventilation at cooling" and "Party level". Setting supply air and extract air is easy byt the touch-panel. A good overview of the supply air and extract air speed for each fan level can be seen under Ventilation settings. Supply air and extract air can be set for each fans speed level in the same screen. 16

17 Compact P / Compact P Polar GEO (English) BY NILAN Humidity control The primary purpose of ventilation is to remove humidity from the home to avoid damages to the building, and simultaneously, to achieve good indoor air quality for the residents. During longer periods of sub-zero temperatures, air humidity in the home may fall to a level which is critical for the building and the indoor climate. Wooden floors, furniture and walls can be damaged by the overly dry air, and dust may be whipped up, impairing the air quality. To remedy this, the control system has an integral humidity control, which maintains a good relative humidity. When the average air humidity in a dwelling falls below a set level (default setting 30%), a decision may be made to reduce ventilation. This will typically only be for short periods. In this way it will be possible to avoid further drying out of the air humidity in the dwelling. The humidity control system also has a function which allows for increasing ventilation if air humidity becomes too high, e.g. during showering. This reduces the risk of mould growth in bathrooms, and in most cases will avoid bathroom mirrors misting up. The humidity control system follows the average air humidity measured over the last 24 hours. In this way, the system automatically adapts to summer and winter conditions. Ventilation Humidity control Low humidity level % 30 % The humidity control calculates the average air humidity measured over the last 24 hours. If the average air humidity in the extract air falls below this level, the "Low humidity" function is activated. Fan speed at low humidity Level 1 / Level 2 / Level 3 Level 1 In case of "Low himidity", the unit changes to the set fan speed level. Fan speed at high humidity Level 2 / Level 3 / Level 4 Level 3 In case of "High humidity", the unit changes to the set fans speed level. Max. time at high humidity (min) minutes 30 minutes The function "High humidity" stops when the actual air humidity is 3% above average air humidity. There is a time limit set, for how long time this function are allowed to run. If it is set to 0 minutes the function is de-activated. Average air humidity This shows the relative humidity in the extract air as an average over the laset 24 hours. Prioritisation sequence in the control system: 1. Userprogram 2 and 1 with high priority for ventilation 2. High ventilation in connection with cooling 3. Low ventilatin in connection with low outdoor air temperature 4. Low average humidity 5. High humidity 6. Userprogram 2 7. Userprogram 1 8. CO 2 level (accessory) 9. Manually set values 10. Week program 17

18 Settings active cooling Depending on architecture, the home may require cooling during summertimer. Compact P has an integral heat pump, primarily used for production of domestic hot water. The heat pump has a reversible cooling cycle, and in the summer time able to cool the supply air while simultaneously producing domestic hot water. Thus, in principle, the cooling is "free of charge". The heat pump i able to cool supply air up to 10 C. and, in order to make it as efficient as possible, it is advisable to raise the ventilation level when cooling is required. However, it must be emphasised that it does not function like an air conditioning unit, because of the low air change. Instead, by cooling the supply air, the indoor air is dehumidified, thus giving a pleasant indoor climate even when indoor temperatures are high. Ventilation Active cooling settings Allow active cooling High fan speed when cooling Fan speed when cooling Minimum cooling supply temp. (ºC) Cooling priority to hot water Description On / Off On With this setting it is possible to select or deselect active cooling via the heat pump. On / Off Off This shows whether it is wished to raise the ventilation level when the unit switches to cooling. NB! The ventilation level i already raised in case of bypass cooling or cooling recovery, and not just in the case of active cooling. Level 3 / Level 4 Level 4 This shows the fan speed level which the unit is to use during cooling C 5 C Here the minimum supply air temperature is set for the air inlet during cooling mode. The standard setting is set low to ensure that the unit can cool on a warm day. On / Off Off Here the minimum supply air temperature is set for the air inlet during cooling mode. The standard setting is set low enough to ensure that the unit can switch to cooling mode on a warm spring day*. *When domestic hot water is needed, the heat pump will run at a higher level, and cannot simultaneously perform active cooling during that period. However, it will open bypass damper if cooling is required. If cooling is to have a higher priority than hos water, the unit will cool the supply air and store the heat in the hot water tank during that period. The hot domestic water will be heated, but not as quickly as usual in hot water production. Prioritisation sequence in the control system: 18

20 Ventilation at low outdoor temperature It is possible to prevent low humidity in the home by reducing ventilation in case of low outdoor temperatures. This function can be used in countries with heavy frosts and at high altitudes where the outdoor air is very dry. The function can also be used if no heating element has been fitted, and the supply air feels too cold in case of low outdoor air temperature. Lower ventilation levels will increase temperature efficiency and thus raise the supply air temperature slightly. The Compact P heat pump is able to heat supply air up to 34 C, in periods where no domestic hot water is produced. Ventilation Low outdoor temperature settings Low fan speed at low outdoor temp. Below outdoor temperature ( C) Fan speed at low temperature Description On / off Off This indicates a wish to operate at low fans speed level in case of low outdoor air temperature C -3 C This indicates the outdoor temperature at which it is wished to start the low fan speed. Level 1 / Level 2 Level 1 This shows the fan speed which the unit is to run at, at times of low outdoor temperatures. Prioritisation sequence in the control system: 1. Userprogram 2 and 1 with high priority for ventilation 2. High ventilation in connection with cooling 3. Low ventilation in connection with low outdoor air temperature 4. Low average humidity 5.

21 Compact P / Compact P Polar GEO (English) BY NILAN CO 2 control ATTENTION A CO 2 sensor is not standard in all units, but may be purchased as an accessory. If the occupancy varies greatly, it may be better to control ventilation by the CO 2 -level in the extract air. This function is often used in offices and schools where loadings vary greatly during the day and from week to week. Ventilation CO2 settings CO2 level, fan speed level 2 CO2 level, fan speed level 3 CO2 level, fan speed level ppm 600 ppm This shows the minimum CO 2 -level at which the unit is to switch to fan speed level 2.

22 After heating element ATTENTION The after heating element is not standard, but can be purchased as an accessory. If it is wished to control the air inlet temperature, it will be necessary to fit a after heating element. A after heating element allows you to control the supply air temperature, regardless of the outdoor temperature. An external electrical or water heating element can be provided for mounting in the supply air duct. Ventilation After heating element Heating element type Min. supply air temperature (ºC) Max. supply air temperature (ºC) None / Water / Electric None This indicates whether a heating element has been installed and if so, what type C 16 C Here settings are made for the minimum suppely air temperature, which the unit must be able to provide when heating is required. The setting applies in the case of an external heat element and for the integral heat pump. NB! The heat pump is unable to heat the supply air while domestic hot water is being produced C 40 C Here settings are made for the maximum supply air temperature, which the unit must be able to provide when heating is required. The setting applies in the case of an external heat element and for the integral heat pump. NB! The heat pump is unable to heat the supply air while domestic hot water is being produced. ATTENTION When there i no need for heating in the dwelling, the supply air temperature may fall below the minimum temperature. 22

23 Compact P / Compact P Polar GEO (English) BY NILAN Temperature settings For smoth, reliable operation, it is important that the temperature settings are correct.

Used for forst protection of water heating elements. When the temperature in the water heating element falls to between 10 C and 5 C a 0-10V siganl is sent to the mixing valve, which allows hot water to enter and attempts to maintain min. 10 C. If the temperature in the water heating element falls below 5 C, the frost thermostat (B3) cuts in and the unit displays a warning: Risk of ice in heating element. When the temperature in the water heating element falls below 2 C, the unit stops and displays a warning: Ice in heating element. 26

27 Compact P / Compact P Polar GEO (English) BY NILAN Frost protection or de-icing All ventilation units with a heat exchanger with high heat recovery rate will be subject to ice formation in the heat exchanger in periods of heavy frost. The unit has an automatic integral de-icing function, which thaws out the heat exchanger if there is ice in it. While thawing is under way, no heat recovery will take place. It is possible to prevent ice formation in the heat exchanger with an anti-frost pre-heating element. Units like the Polar version have an anti-frost pre-heating element as standard. If the unit is not a Polar version, an external preheating element can be purchased as an accessory. Ventilation Frost protection or de-icing Frost protection Frost protection heat exchanger (Compact P Polar) Frost protection heat exchanger (Compact P) Setting: Setting: None / Polar / EHD / BAH Polar This indicates if it is wished to protect the unit against icing and, if so how.

30 Domestic hot water Hot water tanks AIR 9 is a low-temperature heat pump which in addition to heating the house via underfloor heating can also heat the domestic hot water. For users who need extra hot water, Nilan offers two solutions, e.g in the case of a jacuzzi which needs filling. Compact P AIR 9 with an SHW hot water tank The SHW tank is an extra tank usually located next to the Compact P. In it the domestic hot water is preheated by the AIR 9 heat pump to 45 C. The preheated hot water is led from the SHW tank to the DHW tank in the Compact P and further heated by the heat pump in the Compact P before being fed to the taps. Compact P AIR 9 with direct connection to DHW tank AIR 9 can be connected directly to the Compact P hot water tank (DHW) via the solar coil in the tank. In this way, the AIR 9 helps to heat the domestic hot water more quickly. DHW standby function It is possible to set hot water production on standby for a period between 1 and 180 days. In this way, energy on heating the domestic hot water can be saved when on holiday, or in closed holiday cabins during the winter months. The ventilation section continues operation at the set values.

Domestic hot water DHW domestic hot water Hot water settings Hot water set point ( C) Frost protection water tank ( C) Electric heating activates below ( C) Max. water temperature T11 ( C) Supplementary electric heating C 45 C Here the desired temperature for the domestic hot water is indicated. Can also be set on the front of the control panel. On / Off Off On activation of frost protection, supplementary electric heating is switched on at a tank temperature 4 C (T11 or T12) and turns off again at a tank temperature 6 C (T11 and T12). Frost protection will work even if supplementary electric heater is not activated C 40 C This setting will operate independently of the set point for the hot water. Here the temperature is indicated to which the supplementary electric heating will help to heat up the domestic hot water. It is controlled by the T11 temperature sensor at the top. For instance, if many guests are staying in the weekend, it may be beneficial to turn up the supplementary electric heating to ensure sufficient hot water for showers. NB! Requires the supplement electrical heater to be activated C 60 C This setting will operate independently of the set point for the hot water. When Compact P is performing ventilation with active cooling, the hot water tank is used to store the heat from the air. The temperature in the hot water tank may thus increase up to 80 C. If no anti-scald device is fitted, this setting must not be set higher that 65 C, to avoid scalding. If an anti-scald device is fitted, it will be advisable to set the setting to 80 C to allow optimum cooling and to utilise as much energy as possible for domestic hot water. On / Off Off Here it is selected whether supplementary electric heating is required or not. Forst protection will work event if supplementary electric heating is de-activated. 31

37 Compact P / Compact P Polar GEO (English) BY NILAN Central heating Standby functions It is possible to set the central heating to standby for a period or turn i off altogether. If the units is installed in a holiday cabin, the central heating can be suspended for periods in which the cabin is not in use. Central heating Standby functions Central heating on standby Standby period (days) Turn off/on central heating Standard setting On / Off Off It is possible to suspend the central heating for a period which is set below. When the period is over, the central heating system automatically starts up again. The function can be interrupted by pressing off days 1 day Here the number of days can be set for which the central heating is to be suspended. On / Off On Here it is possible to turn off the central heating altogether, if desired. Cooling and heating at the same time The advantage of the same control system for ventilation, domestic hot water and the heat pump is that it makes it possible to mutually adjust operation between them. In principle, the central heating cannot heat the floor heating at the same time that the ventilation is cooling the supply air, as this is a contradictory situation. However, it may occur that the users wants heating in the bathroom floor but cooling via ventilation in the main rooms. Activating this function allows this to be done. Central heating Cooling and heating at the same time On / Off Off Here it is posssible to accept cooling by ventilation at the same time as heating byg central heating, by pressing "On". When "Cooling and heating at the same time" is active, the display will not show a warning, but an event can be read off in the event log to say that this has happend. 37

38 Temperature regulation For smooth, reliable operation, it is important that the temperature settings are correct. The default settings are chosen for normal conditions, but it may be necessary to adjust them for the specific installation. Central heating Temperature regulation Set point flow temperature ( C) 5-50 ºC 25 ºC Here the desired supply temperature for the underfloor heating is set. This temperature can also be set on the front of the display panel. Master sensor T18 / TExt T18 Here the master temperature sensor is set: T18: Temperature sensor in supply buffer tank TExt: External temperature sensor Temperature regulatory deadband ( C) 0 5 ºC 3 ºC Here the regulatory deadband is set for central heating control. Maximum supply temperature (ºC) ºC 50 ºC Here the desired maximum supply temperature is set. NB If, for example, the dwelling has wooden floors and the supplier recommends that underfloor heating does not exceed 35 ºC, this temperature can be set here. This means that the user will not be able to turn up the underfloor heating too high. Supplementary electric heating On / Off Off 2 kw supplementary electric heating can be turned on and off here. Supplementary electric heating helps the heat pump to maintain the correct temperature in the home in cold periods. If the heat pump has not reached the desired set point within 20 min, the supplementary heating starts up. In other words, supplementary electric heating is only used when absolutely necessary. Pause suppl. electric heating (min.) 0 60 minutes 5 minutes If the heat pump cannot achieve the desired set point in operation, this setting determines how much time must elapse before the supplementary heating cuts in.

40 Weather compensation It is possible to choose between a fixed supply temperature in the central heating system or a variable supply temperature, regulated by the outdoor air temperature. A fixed supply temperature is often selected in new houses with good insulation, where the outdoor temperature has less effect on the indoor temperature. A variable supply temperature controlled by the outdoor temperature is often used in houses with a lower degree of insulation, where the outdoor temperature has a bigger effect on the indoor temperature. This ensures there will be sufficient heating in cold periods, while savings will be made on heating in less cold periods. Central heating Weather compensation Regulation mode central heating Set point/ Curve Set point Here it is selected whether to control the supply temperature in the central heating via a fixed temperature or by a weather compensation graph. If set point is selected, the supply temperature is set via the temperature settings or on the front of the display.. If weather compensation graph is selected, the graph is set as shown below On the front of the display it will then be possible to set an offset in relation to the graph instead of a supply temperature. Edit curve weather compensation The graph is set by dragging on the graph points (see below). Offset weather compensation curve ( C) C 0 C If the weather compensation graph does not match 100%, the user can raise or lower the supply temperature via an offset to the weather compensation graph. NB The user cannot alter the supply temperature on the front of the display, but may alter the offset. You can adjust the weather compensation graph by dragging on the points on the screen. 40

41 Compact P / Compact P Polar GEO (English) BY NILAN Hot water production If there is an extra high demand for domestic hot water, the heat pump for the central heating can help Compact P to product domestic hot water. The heat pump prioritises domestic hot water rather than space heating. As it is a low temperature heat pump it can only heat the domestic hot water to a temperature of max. 45 C. Solution 1 (SHW): A 250 litre SHW buffer tank can be connected, in which the domestic hot water is heated to C. When domestic hot water is drawn off, water flows from the SHW buffer tank to the Compact P hot water tank and is there heated to the desired temperature of, say, C. This means that Compact P does not need to spend so much time heating the water and can therefore deliver a larger volume more quickly. This solution is often used where, for example, a jacuzzi needs filling. Solution 2 (DHW): If there is no room for an extra SHW buffer tank, the heat pump for the central heating can be connected directly to the Compact P hot water tank via the solar coil. This will help the Compact P heat pump to produce domestic hot water, allowing more hot water to be supplied. If the heat pump is connected to the solar coil, this will prevent the connection of a solar heating panel. Central heating Hot water production Hot water production required Compressor level (%) None / SHW / DHW None Here it is indicated whether the heat pump for the central heating is to help produce domestic hot water, and if so, which solution is required % 80 % (SHW) / 40 % (DHW) Indicates the compressor level when the heat pump for the central heating is producing domestic hot water. CAUTION When connecting to the DHW tank in Compact P, it is recommended not to set the compressor level above 40%, as there is a risk that the heat pump will trigger a high-pressure alarm If the compressor level with an SHW tank is set over 60%, this will be limited by the limit on outdoor air temperature, if it is set at this level. 41

42 Cooling with GEO The GEO heat pump cannot cool, but it is possible to connect a passive cooling module (not a Nilan supply) which uses the brine temperature to cool the dwelling. Central heating Cooling Passive cooling Cooling method On / Off Off If GEO is to control a passive cooling module, this must be indicated here. The cooling is activated via an external signal. See assembly instructions for connections. Floor / Fan coils Floor Here it is set whether cooling is to be performed via the floor heating circuit or via fan coils, in one or more rooms. Compressor settings The compressor settings are default settings and cannot be changed. This is information as to how the compressor works.

45 Compact P / Compact P Polar GEO (English) BY NILAN User selection programmes It is possible to set two user selection programmes with special settings which override the settings in Compact P. The user selection programmes are activated via an external signal. The user selection programmes are used, for instance, for connecting cooker hood to the ventilation, where the ventilation runs at a high speed when the cooker hood is in function. It can also be used if, for example, there is an open fire or wood-burning stove, and overpressure is desired in the dwelling when lighting them to avoid smoke in the living room.
