Grasslin Thermostats, 1.5 V dc, Maximum of 45 °C

Programmable thermostat and radio frequency control device, which communicates with a mains-powered wall mounted receiver which switches the heat source. The RF transmitter is battery powered, and is intended to be fitted wherever a conventional room thermostat would normally be sited. The controller uses 868MHz radio frequency signals to communicate with the receiver, thereby controlling the boiler according to pre-set or customer’s own time & temperature settings. The 868MHz band is licensed for low-power domestic control systems, and is very secure against interference or accidental operation. Adjacent installations will not be in conflict, because each commissioned control set initiates a unique address (like computer IP addressing for network devices)
