Heating Failure Screen
The Heating Failure screen displays the status of the
fan. If the heating system in the building fails and the
internal temperature drops below 5°C, the unit will stop
running so as to not bring cold air into an already cold
house. The unit will start up every hour and will run for
a short time to measure the temperature of the
property. When the temperature rises, e.g. the heating
system is switched back on, the unit will restart and
continue normal operation.
