Electronic thermostat TM1N/D

relayDIN rail24VAC

TM1N/D is an electronic thermostat to be used in conjunction with Regin NTC temperature sensors. The thermostat has a changeover relay contact and is able to control both heating or cooling functions. TM1N/D is supplied in standard casing for DIN-rail mounting with all settings accessible on the front. Supply voltage The thermostat requires supply voltage of 230 V AC or 24 V AC. See model specifications overleaf. Sensors The TM1N/D is intended for a sensor temperature range 0 ... 30°C, but other temperature ranges are available. See leaflet 6-100 in the main catalogue for choice of sensors. TM1N/D has one output available for connection to sensor input on another TM1N/D or TM2-24/D, when several thermostats are controlled by the same sensor. Setpoint This is set by means of the built-in setpoint knob on the front or with an external setting device. Other scales adapted for other sensor ranges are available External setpoint When using external setpoint TG-R430 or TBI-30, the built-in setpoint knob should be set at 0° thereby eliminating the effect of the built-in setpoint knob. The setpoint knob itself can be removed to avoid the danger of the setting being changed by mistake Hysteresis This is set by means of the knob marked DIFF and is defined as the difference between the relay’s on and off points. Night set-back Night set-back can be initiated by means of an external time switch. When the time switch closes night set-back of 0...10 K from the setpoint value is obtained. Several TM1N/D can be connected to the same external time switch.
