The TFC Group OP-DUOSTAT RF205 Digital is a RF (radio frequency) battery-powered programmable room thermostat which provides six timed temperature periods every 24h. It comes with the thermostat and the transmitter, and the transmitter has a blue backlit display. 

The transmitter for this thermostat runs a pre-programmed user-adjustable comfort / set-back temperature profile. To change this you can simply press the up or down control button at any time, and the temperature setting will be manually adjusted. The receiver must be wall-mounted adjacent to the boiler; it provides volt-free switching, displays indicator LEDs (showing power, load status, and RF comm's activity). 

The transmitter and the receiver are pre-linked in the factory, and they are easy to set up; see the installation videos in their respective tab.
