Wiring of a system with Walltherm
®
, storage tank
and a solar system
Info: The electrical sensors (exhaust gas temperature and
water temperature) on the Walltherm
®
are to install on the follow positions:
Sensor water temperature
Exhaust gas

R2 – pump boiler stove (without PWM)
R3 – el. air flap
T1 – sensor solar panel
T2 – sensor lower storage tank
(Sensor position: lower storage tank
but higher than the return flow of the
boiler stove)
T3 – sensor water Walltherm
T4 – sensor fume temperature
Walltherm
®
(red cable)
T5 – sensor higher storage tank
Important:
The regulation WAL03 can only work with
high efficiency pumps without PWM)
