8 - OPERATION The operating modes are selected using the rotary knob on the front of the control unit (see chapter 6.1 and user's manual). 8.1 - HEATING MODE 8.1.1 - HEATING OPERATING DIAGRAM Max. water temperature (parameter 30) Water temperature setpoint Water temperature resulting setpoint curve An outside temperature X determines a resulting water temperature setpoint Y. The parameters determining this water rule can be set by the installer (see the table in paragraph 8.7). The resulting setpoint is displayed at parameter 04. If required, it can be corrected depending on the ambient temperature of the zone and the automatic slope correction (see paragraph 8.1.5.). Min. water temperature (parameter 32) Generator shutdown threshold (parameter 20) 2K Y Regional min. temperature (parameter 21) Supplementary boiler authorization threshold (parameter 22) Generator authorization Supplementary boiler authorisation 2K X 2K Outside temperature No heating setpoint (parameter 23) If generator alarm or if generator prohibited due to excessively cold water or load shedding Circulation pump activation 8.1.2 - "COMFORT" HEATING MODE Temperature setpoint - The heating can operate only if the outside temperature is less than the non-heating temperature. - The generator is controlled via the heating board according to a resulting setpoint of the installation's outgoing water temperature (factory setting) (*) calculated according to an adjustable water rule determined by: - the non-heating temperature (parameter 23), - the regional minimum temperature (parameter 21), - the minimum temperature of the water circuit (parameter 32), - the maximum temperature of the water circuit (parameter 30). Note: the control can be configured on the installation's return temperature using parameter 57. The resulting setpoint calculated in this manner can be corrected by the temperature of the zone. A difference of +/- 1 degree of ambient temperature in relation to the heating setpoint temperature of the zone (adjustable from 15 to 25 C) causes the resulting setpoint (water temperature) to decrease or increase of 2 degrees, respectively. However, this variation cannot exceed +/- 4 degrees. In addition, a self-adapting system (if activated by the parameter P74) automatically adjusts the heating slope according to the difference between the set point (ambiance) and ambient temperature. See details in paragraph 8.1.5. If the installation's water temperature exceeds the generator setpoint value, it shuts down and heating is provided by the boiler only. Caution: Make sure that the boiler setpoint allows the water temperature of the resulting setpoint to be obtained. (*) The control can be configured on the installation's return temperature using parameter 57. 11

Supplementary boiler - The supplementary valve is activated (and the boiler authorised) if the generator is not able to maintain the installation's water temperature at the calculated value (resulting setpoint). Proportional supplementary valve control (see below) Resulting setpoint Open Close BP = Proportional strip (parameter 38) BP BP Neutral zone (parameter 39) Supplementary boiler authorisation Generator command Water temperature Supplementary heating control shift (parameter P40) - Caution: During normal operation, supplementary heating is authorised only if the outside temperature drops below the authorisation threshold (parameter 22). However, it may be authorised for higher temperatures if the generator is unavailable (due to an alarm, safety cut-out or load shedding. If an alarm occurs on the boiler, the supplementary valve closes (and the boiler is no longer authorised). Alternative generator / boiler operation: If this type of operation is selected (parameter 72 = 0), simultaneous operation of the generator and supplementary heating is prohibited: if the outside temperature is below the authorisation threshold (parameter 22), the generator shuts down and heating is ensured only by the boiler. Control characteristics of the supplementary valve: - The control issues a 230 VAC chronoproportional 3-point control signal (opening/closing).. Time base = Valve action time (parameter 63) 10 Difference (setpoint/ water outlet temperature). Percentage of the control time = Proportional strip (parameter 38) This percentage is displayed in parameter 17, ("+" sign = open, " " sign = closed). In the neutral zone (parameter 39), the valve is not controlled. - Supplementary valve in mixed operation (see hydraulic diagram, paragraph 4). - Valve motor designed to accept opening and closing orders permanently. - In the case of a reversible floor installation, the valve must be equipped with a limit switch that detects the "Valve closed" position to prevent sending cold water into the boiler circuit in cooling mode. The valve accessory 70600116 is used for this purpose. Generator operating safety features in heating mode: - A safety device on the water temperature (installation return) prohibits generator operation if this temperature is below the thermodynamic heating authorization threshold (parameter 36). In this case, only the boiler is authorised to raise the water temperature and allow the generator to function, regardless of the outside temperature. The activation of this safety feature is indicated by the flashing of the display. - Generator operation is prohibited if the outside temperature is below the generator's shut-off threshold (parameter 20). Only the boiler is authorised. 12

8.1.3 - "ECONOMY" HEATING MODE The switch to "ECO" mode lowers the ambient temperature setpoint by a value than can be adjusted from 1 to 6 K (parameter 24). It can only be activated in heating mode (inactive in cooling mode). Switching from "Comfort" to "ECO" is accomplished either by hourly programming, weekly programming by zone or by actuating the rotary knob for the entire installation. In the case of hourly programming, the user can activate a temporary override (1 hour + periods of 1 hour during the current day) per zone. 8.1.4 - "ANTI-FREEZE" HEATING MODE (prolonged absence) Selection is made using the rotary knob on the control unit for the entire installation. The resulting water temperature setpoint shifts to an adjustable value via parameter 29. The heating (generator + boiler if required) is actuated according to the ambient temperature setpoint, which can be adjusted by parameter 25. 8.1.5 - SELF-ADAPTING HEATING SLOPE System activated by parameter 74 = 1. Principle: the theoretical slope calculated according to the parameters of the control equipment is automatically corrected by the system by adding (or subtracting) a correcting coefficient (the value of which is displayed in parameter 90). This coefficient is determined by analysing, in terms of a 24-hour continuous operating period in "Comfort" heating mode, the behaviour of the ambient temperature in relation to the setpoint temperature (in "Comfort" mode). This analysis is also weighted by the difference between the setpoint and the outdoor temperature. Example: (P) = Theoretical slope (P + K) = Slope increased with ambient temperature below the setpoint (P - K) = Slope decreased with ambient temperature above the setpoint Note: Regardless of the slope, the resulting setpoint cannot exceed the maximum temperature value of the water (parameter 30) (possibly corrected according to the ambient temperature). Example: To adjust the following parameters:. Parameter 21 = 0 C. Parameter 23 = 20 C. Parameter 30 = 60 C. Parameter 32 = 30 C 60-30 Theoretic slope value P = = 1.50. 20-0 Max. water temperature (parameter 30) Min. water temperature (parameter 32) Anti-freeze mode ambient temperature setpoint Water temperature Heating command Ambient temperature If the value of the coefficient K read on parameter 90 is 10 (hundredths), the actual slope becomes: P + K = 1.50 + 0.10 = 1.60. The value of this coefficient is reset in the event of: - deactivation of the system by parameter 74, - re-initialisation of the parameters by parameter 60, - an application change by parameter 70. 8.2 - COOLING MODE Active only for the Heating / Cooling reversible floor. - Parameter 70 set at 3 (floor 1 zone). - Parameter 71 set at 1 (reversible). Selection is made using the rotary knob on the control unit. During mode selection, the main circulating pump is triggered and the supplementary valve is closed (to isolate the boiler circuit). (P) (P-K) Regional min. temperature (parameter 21) Peak limiting (P+K) Outside temperature Heating authorisation threshold (parameter 23) 13

Temperature setpoint Cooling ambient temperature setpoint - The generator operates with its own water temperature setpoint (recommended setting: 22 C installation return). It is recommended if the ambient temperature is greater than the cooling setpoint (adjustable from 20 to 30 C). However, Generator command the generator is stopped if the installation's return water temperature is below the minimum water temperature (parameter 34). Ambient temperature Generator operating safety features in cooling mode - Generator operation is prohibited if the installation return water temperature is above a threshold (parameter 35). The activation of this safety feature is indicated by the flashing of the display. - An "anti-condensation" device on the installation's outgoing temperature prohibits generator operation if this temperature is below 15 C. This device is designed to limit the risks of condensation. - Generator operation is prohibited if the supplementary valve is not closed. In this case, the "VA" alarm message is displayed. 8.3 - FORCING OF CONTROL OUTPUTS Forcing: for maintenance operations only, when the system is "OFF", it is possible to force the control of the following outputs by setting to parameter to "1": - Parameter 65: circulating pump - Parameter 67: generator - Parameter 68: heating / cooling inversion output shut down (for reversible floor only) - Parameter 69: supplementary valve opening (and boiler authorisation) Caution: At the end of the operation, forcing must be deactivated (by returning the parameters "0") before restarting the installation. 8.4 - GENERATOR LOAD SHEDDING This can be done: - either by a potential-free contact, - or from a " Tele-Info signal sent by the electrical utility meter (per specification EDF HN 44-S-81). Restricts the operation of the generator (in heating mode and in cooling mode) and the 2 nd electric convector zone, if any. Signalled by icon on the display unit. 8.5-2 nd ZONE - ELECTRIC CONVECTORS A2 nd zone equipped with electric convectors can also be managed (Max. number = 20). These appliances must be equipped with an electronic thermostat (not included) able to receive signals via a 230 VAC pilot wire (standard GIFAM 4). The 2 nd zone is activated by setting the microswitch in the back of the control unit to the "ON" position. - In "Comfort", "ECO" or "Anti-freeze" heating modes, the corresponding signals are transmitted to the 2 nd zone. - In Off position, the signal is transmitted to the 2 nd zone. - In heating mode with hourly programming, the "Comfort" or "ECO" signals are transmitted to the 2 nd zone according to the corresponding hourly programming. - In cooling position, the signal is transmitted to the 2 nd zone. Note: In case of load shedding, a shut-down signal is transmitted to the 2 nd zone. - In heating mode, the display unit indicates for the zone 2 "HEAT. 8.6 - CIRCULATOR CONTROL In heating mode (Comfort / ECO / Anti-freeze), the installation's circulating pump is actuated if the outside temperature is below the non-heating threshold. In cooling mode, the circulating pump is actuated as soon as the mode is selected. Circulating pump shutdown is delayed 1 minute. A degripping device allows the circulating pump to start automatically, for 3 seconds every 24 hours, if it is off. The circulator must have its own thermal protection (not supplied). Note: The circulating pump built into the generator is factory-set to operate constantly as soon as generator power is on. It is possible to operate this circulating pump only when the generator is controlled by this system. To do this, on the generator's ECH regulator, change parameter H20 to 4 (see generator manual). 14

Automatic reset: the alarm disappears when the source of the fault is corrected. Note: The alarms are displayed even if the system is shutdown. If several alarms occur simultaneously, the various codes are displayed alternately. (*) See the type of fault on the generator. 8.9 - TELEPHONE CONTROL Use in heating mode only ADELTA-DORE TYPHONE 500 type telephone control box can be connected to the communication bus (available from DELTA-DORE distributors). Caution: Its date-code number must be greater than 05-24. Consult the manual supplied with the telephone control. By calling the telephone line on which the TYPHONE is recorded, the user can: - know the ambient temperature of zone 1, - know the setpoint temperature of the current mode of zone 1, - send an override setpoint. In case of setpoint modification, zone 1 and possible zone 2 operates in COMFORT mode. This override is indicated by an index on the LCD. Any action on the rotary knob deactivates the override and extinguishes the indicator. Parameters possibilities: - access code change (parameter 62), - interface language change - French / English (parameter 61). 8.10 - POWER FAILURE In case of power failure, the parameters and settings are maintained. If the power outage exceeds 6 hours, the time setting will have to be corrected. 8.11 - MISCELLANEOUS Mode changes using the rotary knob (Heating / Cooling / Anti-freeze / Stop) are delayed 10 seconds in order to filter inappropriate actions. However, the "Time Setting" and "Hourly Programming" positions do not have the time delay feature. The authorization thresholds on the water temperature are cut-off values with a differential of 1K for the reset. 19

9 - STARTING - MAINTENANCE IMPORTANT NOTE Before doing any work on the installation, make sure it is switched off and all power supplies locked out. Any work must be carried out by personnel qualified and authorised to work on this type of machine. 9.1 - STARTING 9.1.1 - PRELIMINARY CHECKS Check: Ensure that the hydraulic connections are properly tight and that the hydraulic system operates correctly: - purge of circuits, valve position, hydraulic pressure (1.5 to 3 bar). For leaks. Electrical cables and wires are well secured to their connection terminals. Loose terminals can cause heat build-up on the terminal board and malfunctions. Ensure that the electric cables are properly protected from all sheet metal edges or metal parts that could damage them. Ensure that control cables and power cables are properly separated. Check that the unit is properly grounded. For tools or foreign objects in the units and control box. The correct installation of the heat pump and boiler. These elements must be ready to operate. Refer to the corresponding manuals. 9.1.2 - CONTROL PARAMETERISATION Parameterisation is performed on the control box. Set the button on the installation's control box to OFF. Control power on. Check the parameterisation and, if required, adapt it to the type of application and according to the installation conditions (see paragraph 8.7). 9.1.3 - ADDITIONAL CHECKS With the control box button on OFF, turn installation power on. Force operation of the installation's circulating pump. Make sure that the generator's circulator is operating and adjust the water output as required (with the control valve). Check that water is properly circulating in the installation (valve position). Make sure to purge the circuits and check the hydraulic pressure. Make sure that the generator has started in the desired mode. Make sure that the supplementary valve is operating, possibly by forcing the opening. Check the generator and boiler setpoints. Check the indications of the temperature sensors; perform an Offset calibration of these sensors if required. 9.1.4 - START-UP Position the control box button on the desired operating mode. Check general installation operation (temperatures, outputs,...). CAUTION: In order for the automatic heating slope correction system operate at an optimum level, we recommend that, when starting the installation, the system be operated in Comfort heating mode for 2 to 3 days without modifying the ambient setpoint. Proceed in the same manner if the correction coefficient was reset. See paragraph 8.1.5. 9.2 - MAINTENANCE Perform the following operations at least once per year (the frequency of operations depends on the installation and operating conditions): - Check the composition and condition of the coolant. - Check operating points and setpoints. - Check the safety devices. - Dust the electrical box. - Ensure that all electrical connections are properly tight. - Check the ground connections. - Verification of the hydraulic circuit (cleaning of the strainer filter and drip pan, water quality, purge, pressure, etc.). - Verification of the supplementary valve. For the generator and the boiler, refer to the instructions specific to these devices. 20
