The Wall Controller is coin cell battery powered. The product is intended primarily for residential applications.

Heatit External Room Sensor is designed for use with Multireg and Heatit thermostats. The sensor can be mounted directly on a wall or on top of a standard European wall box. It can be used with most frames that are adapted to System 55. The product comes in a matt version. When used with a thermostat, dimmer or other products that emit heat, it is recommended that the sensor be mounted below these other products. It is not possible to connect the sensors in series or in parallel.
