The equiflex NRT210 and NRT220 electronic room-temperature controllers are used to provide intelligent unitary control, e.g. in hotels, residential and commercial premises. The controllers are mainly used to activate thermal actuators and to switch auxiliary heating and chilling equipment. The temperature sensor integrated in the controller enables the room temperature to be measured directly. The user is able to adjust the temperature setpoint by turning a rotary knob. A digital input provides the ability to change from occupied to non-occupied mode. The NRT210 is designed for 2-pipe, the NRT220 for 4-pipe systems.
