OPERATING INSTRUCTIONS
At the fi rst installation the thermostat, the time and the day
of the week needs to be set (see encoder paragraph). After
this, a desired thermostat status must be selected (see

desired room temperature selected.
When in PARTY mode the heating request is ON all the
time according the desired room temperature selected.
When in OFF mode, the heating request is OFF all the time
(frost protection is ON).
The thermostat is pre-programmed with a default heating
