Operation with the time switch
The 24-hour time switch has 96 time segments. Every hour is di-
vided into 4 time segments of 15 minutes. The time switch has to
be reset when commissioning the appliance and after any power
interruption. To do this, turn the time switch clockwise until the
marker arrow points to the current time.
To select the required heating time, proceed as follows:
Press down the time segments around the circumference. Red
markings will become visible, indicating the preselected heating
time at which the appliance automatically starts to heat. If the
required room temperature has been reached during the heat-up
time, the appliance switches off. It starts again if there is a further
heat demand and will continue doing so until the selected heating
time has elapsed. This process is repeated daily. The heating time
can be adjusted at any time if required by pressing time segments
up or down.
5.2 Stopping heating / frost protection
f Turn the temperature selector fully anti-clockwise. f
In this setting, frost protection is only ensured if the rocker switch
is positioned for "Standard operation". The heating system starts
automatically if the room temperature drops below the frost pro-
tection temperature.
