Description of functions
Electrical 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 the electrical heater in sequence.
The GT1 sensor is used to limit the
max and min supply air temperature.
Maximum temperature in the electrical
re-heater is controlled by GTM. GTO
disconnects the heater, gives an alarm
signal and stops the appliance in case
of overheating.
ST1 closes the fresh air damper when
the appliance is stopped. 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.
