Use grounding terminals!
The controller calculates the temperature difference
between solid fuel boiler sensor S1 and store sensor
S2. The relay (RO) is energised when both switch-on
conditions are fulfilled:
• the temperature difference has exceeded the switch-
on value
• the temperature at the solid fuel boiler sensor has
exceeded the minimum temperature
If the temperature difference falls by 1.6 K (non-adjust-
able hysteresis) below the adjusted temperature differ-
ence, the pump will be switched off.
S1 = Solid fuel boiler sensor
S2 = Store sensor
RO = Circulating pump

Troubleshooting
Spare fuse
(inside the cover)
In the case of an error, please check the following:
Check the supply line and recon-

The fuse of the controller could be
blown. The fuse holder (which holds
the spare fuse) becomes accessible
when the cover is removed.The fuse
can then be replaced.
Check the power supply of the controller. Is it disconnected?
