Joint alarm
External heat supply
It may be difficult to notice alarms if the unit is located in a place where access is
difficult or infrequent, and if the control panel is located in the same place.
An external alarm indicator in the form of an electric bulb or an acoustic signal
can be connected to the ventilation unit and announce when an alarm occurs.
This could, for example, be when filters need replacing.
The unit can control an external heat supply, such as electric radiators
or an underfloor heating system. This feature is used in the cases
where the unit contributes to the heating of the house via a heat
pump and/or a after-heating element.
The room temperature is monitored by the unit's control system,
which only releases the external heat supply if it cannot heat the
home/house to the desired room temperature.
External heating supply is connected to the expansion PCB via relay
R8, and the settings are set in the control panel.
Read the software manual to see which settings to set.
