Programmable regulator for a heater - has printed circuits with thermostatic control circuits

摘要

There is a plate with a printed circuit to which a selector, inside the regulator, is connected by its individual switches, the switches have two positions, one for winter the other for summer. The regulator is fitted with a double thermostat connected to the circuit by its regulator and safety switches. The temperature detectors are placed outside the regulator casing and the plate has, in some areas of the printed circuit, connections for the cables establishing the contact with the electric components of the control mechanism and in other areas, the circuit is interrupted by points inter-connected in pairs as a function of the programming.
