This accurate and easy to use wireless programmable thermostat provides you with time and temperature control, so you remain comfortable but without wasting energy (and money). You select the temperature you want and at what times. The RSTAT5 RF is free standing and portable, offering the additional installation benefits that come with RF (wireless) controls, i.e. no long fixed-wiring runs, no lifting floorboards, no channelling walls and no subsequent re-decorating. The programmable controller transmits unique, secure radio signals up to 30m away to a hard-wired receiver unit located close to the boiler or other appropriate control component. The RSTAT9 RF can be moved around the home as you do, monitoring the temperature of whichever room you prefer. The default switching programme, which is easy to modify as desired, makes setting your heating times even easier. Up to six automatic changes of room temperature each day allow the heating system operation to match your own lifestyle. The boiler is used only when required, improving your family’s comfort and making substantial energy savings.
