Supply the clean air from outside the building effectively by starting this function, and then return to the air change mode, i.e. switch to the STANDARD mode. VOD mode - in this mode, the air supply and exhaust speed depends on the humidity level on the additional outdoor sensor of the heat recovery unit or depends on the level of concentration of CO2. These sensors are available in the offer separately. While still operating in the VOD mode, we will have one of the two following indications displayed or the humidity level indicator and the possibility of setting its lower and upper range....or the CO2 indicator The display of the type of indicators (humidity or CO2) in the VOD mode in the interface depends on the sensor selected during the configuration of the Wi-Fi network at the stage of setting the connected sensors (see page 9 of the manual). 16
Interface - remote control of the heat recovery unit In all the modes - STANDARD, EXHAUST AIR, SUPPLY AIR, VOD - the panel with the following functions, which works as follows is displayed: Connection - shows the proper communication between our By-Pass Function, i.e. supply module and the heat recovery unit of fresh, filtered air indoor, controller. with the omission of the Illuminated marker - correct heat exchanger. connection Illuminated marker - activaalarm code - displays the code that ted by-pass function. identifies the possible error of the heat recovery unit (descriptions of codes are included in the manual). In all the modes - STANDARD, EXHAUST AIR, SUPPLY AIR, VOD - the temperature panel, which functions as follows is displayed: Indoor air temperature - shows the Remotely set temperature temperature of the air removed - you can set the desired from the room and strives temperature in the room. for reaching the remotely set temperature. Temperature of air taken from outside the building. If, during the heat recovery unit setting and Wi-Fi setting configuration we selected the type of the connected heater, in each operating mode of the heat recovery unit - STANDARD, EXHAUST AIR, SUPPLY AIR, VOD - the fields providing information about the type of the heater connected to our heat recovery unit will be displayed - in this case, both heaters are shown. Operating principles for the heaters: 1. Secondary heater: the moment at which the temperature of supplied air is below the temperature set on the temperature panel (in our manual this is 22oC, three screens above), the secondary heater is switched on. At the beginning, it operates with 1/2 of its capacity - i.e. in the first heating level, if it turns out that this capacity is not sufficient, in order to heat the air to the temperature set by us, the second heating level of the heater is switched on. 2. Pre-heater: it is switched on if the temperature of the supplied air falls below the temperature value which was selected by us at the stage of heat recovery unit settings - see the photo in the field: Pre-heater activation temperature [oc]-10. The operation of each of these heaters at a given moment is signalled by illumination of the marker on the left side of their names in the above-mentioned location. After the required parameters of the supplied air temperature are reached, the heaters are automatically switched off and the markers in the interface disappear. GUIDELINE FOR USERS! The heater power should be selected taking into consideration the atmospheric conditions in the given region. NOTE! After connecting the heater to our ventilation system, it is important to switch position 1 and 2 to ON in the electrical box located on top of the heat recovery unit. They are located in a red cube, marked with a white circle in the photograph. Only in this case will they be integrated with our heat recovery unit and read the temperature parameters to which they will adapt their respective operation. 17
Interface - remote control of the heat recovery unit CALENDAR In our interface we can set the operation of the heat recovery unit separately for each day of the week. The lit calendar icon [31] informs us about the fact that the operation is defined according to the calendar. Upon entering the calendar settings, first of all we can mark on which days our heat recovery unit will function according to the calendar settings. The illuminated marker means that on this specific day the heat recovery unit operates according to these settings. On a given day of the week we can set when the heat recovery unit is to be switched on/off. At the operation number we need to click the marker so that it is illuminated and this means that this operation will be active and considered in the operation of the heat recovery unit. By clicking and illuminating the ON button, we define the option of switching the heat recovery unit ON. When the ON button is not backlit, we activate the option of switching OFF the heat recovery unit. (the OFF button which is not backlit will be visible) By using the -/+ buttons we set the selected hour and minute in which the heat recovery unit is supposed to be switched on or off (in this example on the screen on the left side, activation is set - this is defined by the backlit ON position in the On/Off field. Another, second operation can be the setting of the OFF option of the heat recovery unit at a specific time. In the On/Off field, we must deactivate the illumination of the button so that only the word OFF is visible. The activation of the OFF function setting takes place after illuminating the marker next to the operation number (in this case next to digit 2). 18 etc.... There is a possibility of setting 6 freely selected operations.
