There are separate program for different languages. Display need to be ordered with right language. Why unit stops when disconnecting display? Controller program runs in display microprocessor. It needs always to be connected. Temperature The regulator cannot maintain the desired. temperature. What might be wrong? Is the heater battery/cooling battery designed for the prevailing temperature? Investigate whether the water temperatures to the batteries are sufficiently high/low. Investigate whether the electric battery is receiving power. Make sure that no windows or doors are open. Why does the relevant temperature reference value deviate from the values that are set under the reference values? The Summer/Winter compensation function may be activated. This compensation moves the reference value depending on the prevailing ambient temperature. Heating / Cooling The Display shows Alarm Heat Pump although the unit has electric heating. Is the unit incorrectly configured? The alarm text refers to overheating of the electric battery or a circulation pump alarm. The electric heater trips the automatic overheating protection. How is the fault rectified? The air supply temperature is too high. Decrease the reference value or increase the flow; alternatively decrease the parameters for Max. control signal heating under the menu: M2.2 Maximum temp Fläkt Woods 8592 GB Subject to alteration.

18 Operation Värmning/Kylning The unit is switched off but the pump for the heater battery is running. Is something wrong? In the event of low return water temperatures from the battery, the freeze guard function operates the heater battery pump to ensure there is no risk of the battery freezing when the unit starts. The pump is operated every Monday at 12:00 or is set to constant operation. The pump operates constantly at low ambient temperatures. The unit is switched off but the pump for the cooler battery is running. Is something wrong? The pump is operated every Monday at 12:00 or is set to constant operation. Why does the electric battery not produce any heat, even though the control signal is 100%? The parameter for Max. control signal heating may be set at a low level. There is no power supply / operating signal to the electric battery. The overheating protection may have tripped. Why does the unit stop when the external timer is activated? The control inputs can be configured for different functions, for example as external stop, see under menu: P9.1 Timer function. Why the unit won t start although time program should start it? If DIL switch 3 in operation panel is OFF and there is no jumper between terminals AI3 and +VCCOUT, the unit won t start. Change DIL switch position to ON (filter switch) or connect the jumper. AI3 is configured permanently NC with external stop. Miscellaneous Filter alarms are received despite the fact that there is no filter guard. What is wrong? DIL switch 3 in operation panel configures input AI3 as start enable or filter switch. Operation How do I set the time program so that the unit is switched off at weekends? Use the Week program function and set the unit to be switched off between Saturday morning and Sunday evening; also remember to Activate switching. Fläkt Woods 8592 GB Subject to alteration.

Preheating Welcome ÿ Preheating (P16) Effekt Water-heated air heaters are sensitive to frost. If the air conditioning unit is disconnected at night and there are low ambient temperatures at start-up, the sudden supply of cold outdoor air would cause the water in the pipes to freeze. This problem is particularly tangible in conjunction with 2-position dampers. In order to circumvent this, the water circuit is preheated with hot water before the outdoor air damper is opened. At start-up, only the air heater s heating circuit pump starts and the heating valve opens prevailing ambient temperature for an adjustable period of time. The risk of freezing damage is eliminated, and the unit then switches to normal control. Fläkt Woods 8592 GB Subject to alteration.
