The thermostat can be individually programmed to heat (cool) the rooms in your home or office to the temperature you want at the times you want, and help reduce energy costs while providing comfort.

The thermostat is freely portable within range. The connection to the COMPUTHERM Q5RF/Q8RF receiver and/or the COMPUTHERM Q1RX plug is wireless (radio frequency), so no wiring is required between the thermostat and the boiler.

It is recommended for use where there is a need to break down the heating system into zones, programmability, accurate temperature measurement and set-up, portability and switching accuracy are important.

Key features:

• The thermostat is freely portable within range
• A temperature programme can be created for each day of the week.
• It is possible to set 1 fixed and 6 freely selectable switching times per day, each of which can be set to any temperature.
• There are 4 different options to temporarily change the temperature according to the program: until the next program change, 1-9 hours, 1-99 days or until the next manual intervention.
• Selectable switching sensitivity
• Calibration of internal thermometer
• Easy switching between cooling and heating modes
• Pump protection function
• Backlighting
• Key lock

A  COMPUTHERM Q1RX can be controlled simultaneously with up to 12 COMPUTHERM Q3RF, Q5RF, Q7RF and Q8RF thermostats, and can be used in addition to/instead of their receiver units. The device is suitable for controlling boilers or other electrical appliances (e.g. heaters, pumps, zone valves, etc.) operating at 230V. It is simple to install and use and requires no assembly.
The COMPUTHERM Q3RF, Q5RF, Q7RF and Q8RF wireless thermostats are switched on by a 230V mains voltage at the output plug of the Q1RX device connected to the mains, or off by a switch-off command. The device is equipped with an activation and deactivation delay, which allows for multiple applications.

• Power consumption: 0.01 W
• Operating voltage: 230 V AC, 50 Hz
• Output voltage: 230 V AC, 50 Hz 
• Switchable current: 16 A (4 A inductive load)
• Activated output power-on delay: 4 min
• Activated output switch-off delay: 6 min

The switch plug can be used with Q series radio frequency devices purchased after 2016.
