5. Setting controller parameters
5.1 Control method: weather-compensated
or room thermostat
Celcia 20 is both suitable for use as a weather compensator
(the heating water temperature is dependent on the outside
temperature) and for use as a room thermostat (the heating
water temperature is dependent on the room temperature).
Opting for the one or the other depends on the way in which
the installation is set up. The Celcia 20 default setting is for
room control.
If you opt for weather-compensated heating, 4 parameters are
needed to establish the heating curve (connection between
outside temperature and heating water temperature). The ex-
ternal temperature sensor is available as an accessory and
should be connected to the boiler.

tion was also designed (climate point).
NB: if the boiler is programmed for a maximum flow
temperature that is lower than the flow temp. winter,
the value from the boiler applies.
In the case of weather compensated thermostat the room
temperature is measured and displayed, but not used by the
thermostat. If so-called room temperature compensation is de-
sired, connect an external sensor and select room thermostat.
