11.2.2 Electric heater
Operates in two on/off stages or with TRIAC (modulating).
The latter allows the power of the electric heater to be varied to ensure it is as close as possible to the required heating capacity.
The connection is carried out in the factory. The electric heater is equipped with two safety thermostats, one with automatic reset
and the other with manual reset.
