ALRE Electronic Room. Floor and Surface Temperature Controllers with Remote Sensor HTRRB, HTRRBu, FETR

HTRRB Electronic Floor or Surface Temperature Controller with Remote Sensor


HTRRB range (Heating Technology)

HTRRB-011.010 and HTRRB-011.410 electronic floor and surface temperature controllers with remote sensor (for floor, wall and ceiling heating systems and tiled stoves).
To control temperatures produced by heating systems such as electrical systems for the heating of floors, fringe zones, bathrooms, ceilings, tiled stoves, marble and/or wall heating systems or tempering systems.

Please note: the sensor line must be routed in a protective duct. Parallel routing together with lines that carry alternating currents is not allowed.

HTRRB-011.010 Floor temperature controller with remote sensor HF-8/4-K2 4M, multi-digit display. Control range 10 ... 60 deg C

HTRRB-011.410 Tile stove surface temperature controller with remote sensor HF-5/4-K3 4M. Control range 20 ... 80 deg C

For floor temperature controller with clock please see HTRRBu-110.021

For floor temperature controller for distributor assembly please see ITR 79

HTRRBu Electronic Floor Temperature Controller with Clock and Remote Sensor


HTRRBu Range (Heating Technology)


HTRRBu-110.021 electronic floor temperature controllers with timer and remote sensor.
Time dependent control 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).

Floor temperatures 10 ... 42 degrees C. 230V-, 50 Hz.

Please note the sensor line must be routed in a protective duct. Parallel routing together with lines that carry AC voltage is not permissible.

FETR Electronic Floor Temperature controller with Remote Sensor


FETR range (Heating Technology)


FETR 101.700#07 to FETR 101.745#00 electronic floor temperature controllers with remote sensor, flush mounted installation, for temperature control (eg of electrical heating systems) for floor, fringe zone, bathroom, ceiling, tiled stove, marble and wall heating systems or tempering systems, direct floor heating systems.

With these flush-mounted controllers, the temperatures can be reduced by 5 K. To do this potential is applied to the clock input terminal by an external pilot controller or an external timer L1.

Please note the sensor line must be routed in a protective duct. Parallel routing together with lines that carry alternating currents is not permissable.
