HTRRUu Flush Mounted
HTRRUu Range (Heating Technology)
HTRRUu-210.021#21 to HTRRUu-210.021#21/7 range of electronic room temperature controllers with timer for flush mounted installation.
Flush mounted temperature and programmable time controller for electrical or hot water heating systems in rooms or underfloor heating (normally closed actuators). It can be used as a straightforward room thermostat, as a room thermostat with floor temperature monitoring (using optional remote sensor) or as a floor thermostat. (Remote sensor not included)
Setting ranges: Room temperature controller 5 .. 30 degrees C, Floor temperature controller 10 .. 42 degrees C. 230V-, 50 Hz.
HTRRBu Electronic Room Temperature controllers with clock
HTRRBu Range (Heating Technology)
HTTRBu-110.117/21
Electronic room temperature, surface mounted controllers for time-dependent control of temperature in closed spaces. Suitable for all types of heating systems.
Valve actuator: normally closed type. The device can also be used as a master (pilot regulator) for the temperature reduction of other controllers. Controllers of series FETR, RTBSU and RTBSB are suitable as slaves (satellite controllers).
Programming procedures for every day, familiar from mechanical timers, by means of "electronic tabs". Shortest switching time 15 min.
Ambient temperature 0 ... 30 deg C, storage temperature - 20 ... + 70 deg C, control range 5 ... 30 deg C.
HTRRBu Electronic Floor Temperature Controller with Clock and Remote Sensor
For floor heating/wall and ceiling heating)
Time-dependent temperature control (for eg of electrical heating systems) for floor, fringe zone, bathroom, ceiling, tiled stove,marble and wall heating systems or tempering systems.
It can be used as a master (pilot regulator) for the temperature reduction of other controllers. Controllers of the series FETR, RTBSU and RTBSB are suitable for use as slaves (satellite controllers).
Please note the sensor line must be routed in a protective duct. Parallel routing together with lines that carry AC voltage is not permissable.
Programming procedure for every day, familiar from mechanical timers, by means of "electronic tabs". Shortest switching time 15 minutes.
Ambiant temp 0 ... 30 deg C, storage temp - 20 ... + 70 deg C, control range 10 ... 42 deg C.
