Description of functions (Topvex SR E HW)
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 UC
receives a signal from ETS and regulates the
HE and WVA in sequence. The SS sensor is
used to limit the max and min supply air temperature.
If there is a risk of frost in the water heater WVA
opens completely. If the temperature drops further,
an alarm is set off and the appliance stops. FPS
maintains constant water temperature even when
the fans have stopped.
DO closes the outdoor air damper when the appliance
stops. 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.
