matt

Wireless temperature controllers (actuators) used to implement a sin- gle-room climate control in conjunction with alre wireless room temperature sensors.

light grey, similar to RAL 7035

ABS plastic

230 V AC, 50 Hz −10 to +50 °C −20 to +70 °C

Ambient temperature: Storage temperature: Permissible atmospheric humidity: Electrical connection: Mounting / attachment:

Functions: heating, cooling with adjustable neutral zone; H / C

max. 95% rel. humidity, non-condensing

changeover on site or via an external contact; on / off switching by contact with frost protection function; individual channels can be excluded from cooling 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 connection 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.
