The following is a description of the electric wiring for Thermocontrol and H2O 14 / Compact 14: through this electrical
connection, the shut off action by Thermocontrol automatically switches the diverter valve and also switches off the boiler: if the
system Chronothermostat requires more heat the boiler does not switch off until it has satisfied the heating requirements of the
room. The connections to the diverter valve and system chronothermostat are shown in the diagram and in the following photos.
CAUTION: in order to prevent too many boiler start ups, with consequent reduction in the electrical heater lifetime, the
manufacturer highly recommends using a chronothermostat with a thermal hysteresis of at least 2°C.

Caution: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is not
covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing. There
must be no electric potential (volts) between the earth of the generator and the actual earth of the plant. To prevent
electrochemical corrosion of the boiler body do not use galvanised pipes and fittings. Dedicated ground wires
must be used to ground all other materials.
In order to guarantee correct absorption of the heat produced by the generator is it is advisable to use a boiler tube with volume and heat
exchange capacity suitable for the power of the generator.
