Description of functions
Water heating, extract air temperature
control with cascade function.
Function
Start and stop times are set in the
Control panel. To maintain constant
room temperature the RC receives a
signal from GT3 and regulates the VVX
and SV in sequence. The GT1 sensor
is used to limit the max and min supply
air temperature.
If there is a risk of frost in the water
heater SV opens completely.
If the temperature drops further, an
alarm is set off and the appliance
stops. GTF maintains constant water
temperature even when the fans have
stopped.
ST1 closes the fresh air damper when
the appliance stops. In case of an
unintended stop on the rotor, the RCR
gives an alarm, which is displayed on
the Control panel as an alarm.
Also displayed in the Control panel are
date and time, operating status,
desired and actual room temperature.
GP1 and GP2 give alarm signals when
the actual value exceeds the pre-set
desired value for pressure drop over
the filter.
