The room controller in the zEaton designz records the temperature and sends it to the convenient electrical installation. It can be used for simple individual room control (heating) as well as conservatory control (shading). This device offers additional convenience for the end customer (day/night reduction switch) and the professional (refresh button for commissioning). The device is powered by two AAA batteries and can therefore be easily installed anywhere (screwed and glued). Due to the flat design, NO switch, junction or installation box is required. Attention: For exact measurement and display of the values, record the deviation using a reference measuring device and set the offset in the MRF. The mounting base plate makes installation much easier. Batteries included in delivery. Attention: this room controller cannot under any circumstances be used for the application with the zHeating actuator for E-Panelez!!!
