A night blind is opened when the appliance cleaning function is activated.
A setting can dene that the night blind is opened when "r12" (Main switch) is set to o (see o98).
When the night blind rolls down, the fan will be stopped for the set time. The night blind can thereby roll down to
the correct position.
Heating function (only with custom set-up)
The heating function is used to prevent the temperature from becoming too low, e.g. in a cold room, etc. The limit
for when the heating function cuts o is set as an oset value below the current cut-out limit for the refrigeration
thermostat. This ensures that refrigeration and heating do not occur simultaneously. The dierence for the heating
thermostat has the same value as for the refrigeration thermostat. To prevent that the heating thermostat cuts in
during short-term drops in air temperature, a time delay can be set for when to change from refrigeration to
heating.
