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.

Humidifier
Functions only with municipal water, and not with demineralised or softened water.
The humidifier with immersed electrodes has a card mounted inside the box to relay all information relating to the humidifier directly
to the CCU CONTROLLER. It adapts, within the allowable operating limits, to the physical and chemical properties of the water used.
Voltage is applied to the immersed electrodes, and an electrical current passes between them, heating the water to boiling point. The
water acts as an electrical resistor, ensuring continuity between the electrodes with a minimum of dissolved salts.
(The water must have a conductivity of between 350 µS/cm and 125 µS/cm.)
