KTRRUu257.456#55/V2

Room thermostat with clock, heating/cooling, flush-mounted, 24VAC/VDC, cover 55x55mm, pure white, glossy

Flush-mounted controller for time-dependent heating/cooling control of 2- and 4-pipe systems in hotels, residential and commercial premises. Can be adapted to almost all surface switch programs thanks to different variants. Up to 5 valve actuators (normally open or closed) can be controlled per output. In 2-pipe operation, the operating mode can be switched via an external contact (change-over), temperature sensor or in the menu. The clock can be used as a master for other controllers for ECO switchover. The energy-saving function (ECO) or frost protection (STANDBY) can be activated via an external contact. Alternatively, the controller inputs can be configured for an external temperature sensor (weighting between internal and external sensor can be set) or a dew point sensor (TPS). A fan (EC fan) can be speed-controlled via a 0 … 10 V interface.
