Central heating temp. control system - has damp proof ambient temp. thermostats connected to multiple thermostats for regulating burner

摘要

The temp. control system is for central heating equipment using hot water, having an ambient temperature detector connected to the boiler burner control circuit. This detector is divided into two damp-proof encapsulated thermostats (1, 2) each having a fixed predetermined temp. reaction value. These individual thermostats are connected to a multiple one (4) cutting the burner in and out (3) and incorporated in the boiler control circuit. the number of switching stages (5) of the multiple thermostat is one greater than that of the outside thermostats (1, 2).
