7.1 General
Control unit (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
15
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.
Note:
This instruction contains functions for the Topvex SoftCooler TR, for a complete description of functions see
