Wireless room thermostat set Mi-250S RF
The Mi-250S RF wireless room thermostat set is an optimal solution for heating control when no cable is available. The set consists of a battery-operated transmitter (2x AAA batteries) and a mains-voltage supplied receiver (230V / 50Hz). Transmission between the two devices is wireless via a 433MHz radio connection with a range of up to 20 metres. The wireless room thermostat set is equally suitable for new buildings or renovations and can be easily removed again if required.
The control is designed for comfortable and economical heating operation and can control centrally the boiler, electric heaters, water-guided underfloor heating with NC or NO actuators, as well as other consumers with a maximum switching capacity of 7A (amps). Almost all consumers can be switched via the potential-free switching contact. The temperature is monitored via the integrated sensor on the wireless transmitter.
A total of up to 3 wireless receivers can be taught-in at the room thermostat transmitter. This means that even larger rooms with several heating sources can be controlled very conveniently. The battery-operated transmitter can either be surface-mounted on the wall or positioned at the desired location using a table stand.
