Description of functions (Topvex SR E EL)
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
UC receives a signal from ETS and regulates
the HE and the electrical heater in sequence.
The SS sensor is used to limit the max and min
supply air temperature. Maximum temperature in the
electrical re-heater is controlled by ET.
OT disconnects the heater, gives an alarm signal
and stops the appliance in case of overheating.
DO closes the outdoor air damper when the
appliance is stopped. In case of an unintended stop on
the rotor, a signal is sent to RC, 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.
FGS and FGE give alarm signals when the
actual value exceeds the pre-set desired
value for pressure drop over the filter.
