External heating control
T
he unit can control an external heat supply, such as electric radiators or an underfloor heating
system.
The unit monitors the room temperature and blocks the external heat supply when heating is not
required. If, through ventilation alone, the unit is unable to heat the room to the desired temperature,
the external heat supply will be released until the room temperature has reached the desired level.
Connect the external heat supply via relay 8 on the expansion PCB. Adjust the settings on the panel
under the menu option: Service settings / Temp. Regulation.
Expansion PCB
You can connect a maximum effect of 500W (The unit must be fitted with a transfer relay).
