The Honeywell T4R thermostat (wireless) automatically controls heating and cooling in flats and houses according to the set time programme. Up to 6 time periods can be assigned to each day for temperature settings. Several modes can be set, for example a weekly programme (7x1 or 5+2) or holiday mode, where setback temperature can be set for up to 99 days.

Its modern, minimalist design fits into any home (vertical or horizontal installation). Thanks to the large backlit display, it is easy to read in all lighting conditions. Via a volt-free relay, various heat sources can be controlled, such as a gas boiler, electric boiler, circulation pump downstream of a buffer tank, shut-off valve actuator or heat pump. The T4R version is a wireless thermostat (a set including a display unit and a wireless switching unit) - the display unit can be placed either on the wall or on a horizontal surface.
