Connecting a boiler without thermostat
input
If the boiler does not have a thermostat
input, you can directly control the circula-
tor which is located next to the boiler (the
pump enabling circulation of the hot water
into the radiators).
- Directly control the power supply to the
circulator using the thermostat.

Controlling electric convectors
To control electrical convectors, you MUST
use a power contact switch that is suitable
for the total power to be controlled.
This power contactor switch must be fitted
into the electrical switchboard of your home.
