Remeha Avanta Plus
10 EXPANDING THE CENTRAL HEATING SYSTEM
Connecting thermostats
A 2-wire on/off thermostat (e.g. the Remeha Celcia 10) or to a
modulating thermostat (e.g. the Remeha Celcia 15 or 20) can
be connected to the Avanta Plus. Consult the installer about
connecting the thermostat you have chosen.
Connecting an under floor heating system
A under floor heating system can be directly connected to the
Avanta Plus
(provided it is sealed to prevent oxygen diffusion).
Consult the installer about connecting to a floor heating sys-
tem.
Use of solar panels
The Remeha Avanta Plus is suitable for use as a post-heater
for solar panels. Consult the installer about installing a solar
panel.
