7.1 General
Control unit E28 (UC) senses the temperature via the extract temperature sensor (ETS) and then keep
the set extract temperature by sequence controlling the compressor (CPR), heat exchanger (HE) and
hot water- /electrical heater (HWL/H, ELH). The temperature sensor in the supply air (SS) is min. and
max. limiting the supply air temperature.
7.2 Cool recovering
Exchanger (HE) will automatically start to recover the cold in the extract air when the extract air is colder
then the outdoor air.
7.3 Power control
The compressor (CPR) are step-less controlled between, in the frequency converter (FC), set minimum
and maximum frequency.
7.4 Power limitation
The frequency converter (FC) is continuously sensing the condensing pressure via the high pressure
sensor (HPS) and gradually slows down the speed of the compressor (CPR), if the pressure exceeds
the set limitation value. This is done to avoid a high pressure alarm.
7.5 By-pass function (option)
To reduce the energy use for the extract fan when there is no cooling demand the exhaust by-pass
damper (accessory) is opened and thereby the exhaust air does not pass the condenser (CO). At stopped
unit all dampers are closed.
