Thermostats

These are devices for the control of cabinet temperature, if they are connected to fans and resistances, or to signal alarms.
The contact of the TMF341 thermostat (BLUE) is normally open and can be used to signal temperature alarms or to control the ventilation systems.
The contact of the TMF 342 thermostat (RED) is normally closed and can be used both to signal alarms and to control anti-condensation resistances.
The installation of both is foreseen on the DIN bar and adjustment is performed with a screwdriver.
