Electronic room thermostats for DIN rail mounting.
FREEZE PROTECTION UNIT
The electronic frost protection unit is primarily intended for use in air handling systems. If the temperature falls below the setpoint, the relays are released and the alarm LED illuminates. The device must be connected to an NTC sensor mounted on the heating coil or return water pipe. The frost protection unit has two alarm relays and manual or automatic reset. The sensor must be in the temperature range 0 ... 30 ° C.
If there is a risk of frost, the device has a 0 ... 10 V DC control output to override the valve.
THERMOSTAT, SINGLE STAGE, MOUNTABLE ON DIN RAIL
Electronic thermostat for heating and cooling. Adjustable night reset with external clock. Multiple thermostats can be connected to one sensor.
THERMOSTAT, TWO STAGE, DIN RAIL MOUNT
Thermostat with two relay outputs and separately adjustable stages for heating and cooling. Sequential or binary function.
SCALE FOR OTHER TEMPERATURE RANGES
Alternative setpoint scale for thermostats TM1 and TM2 when using sensors with different temperature ranges.
