Wireless temperature controllers (actuators) used to implement a single-room climate control in conjunction with alre wireless room temperature sensors. The actuators can also be connected to the sensors directly without the b@home gate to implement single-room control. Functions: Heating, cooling with adjustable neutral zone; H/C change- over on site or via an external con- tact; on/off switching by contact with frost protection function; individual channels can be excluded from cool- ing operation; cooling interruption if condensation occurs, via dew point sensor or contact; cooling limit 18 °C; energy-saving function centrally via external timer or centrally or locally in master-slave operation, (max. 4/8 time zones possible, i.e., up to 4/8 sensors can be connected to clock); status display of the wireless con- nection for each channel, automatic emergency mode if connection lost; The upper part can be removed for configuring the wireless sensors/ channels in the individual rooms. The power supply is ensured during this time with a standard commercial 9-V block battery. The sensors can be configured easily using the channel selection button and a learn button. Attachment: There are 4 screws for wall attachment that are part of the standard kit; as an option, a magnetic attachment set JZ-24 for simple attachment in the heating manifold distribution cabinet can also be supplied.
