TRM-MOD-230
TRM room thermostat measures and controls room temperature. You can use it as a controller in many traditional HVAC applications, including 2- and 4-pipe fan coil applications, and air conditioning with heating and cooling functions.

This room thermostat has six relay outputs: three for 3-speed fan, two for valve control and one for a condensate pump or a heater. It also has one voltage output for an EC fan.
The TRM room thermostat has one resistive input and one digital input. You can connect an external NTC 50 temperature sensor to the resistive input, for example, to measure return air temperature. The digital input allows you to connect an external switch to the thermostat for heating/cooling changeover in a 2-pipe system. Alternatively, you can connect an occupancy sensor or a switch to the digital input for switching the thermostat ON and OFF.
The room thermostat has a backlit, easy-to-read LCD display with 0.1 °C resolution. Users can easily adjust the temperature setpoint using the buttons adjacent to the display. The thermostat also has a built-in timer for switching the thermostat OFF.
Commissioning the room thermostat is simple. You can select the basic configuration with DIP switches according to your application. You can configure other settings through the user interface or via Modbus communication. This room thermostat can be flush mounted on the wall or installed directly into a HVAC unit. The thermostat is compatible with the 503 flush mounting boxes.
