HTRRB-011.010
Underfloor temperature controller with remote sensor, surface-mounted, 10-60…°C
For temperature control (e.g. electric heating) for floor, edge zone, bathroom, ceiling, tiled stove, marble, and wall heating or temperature control systems.
Electronic underfloor temperature controller for electric underfloor heating up to 3000W. The setting range can be adjusted using the range reducer located under the adjustment knob (e.g. 10…40…°C). Remote sensor HF-8/4-K2 (4m) included in delivery. In the event of a sensor failure and short circuit, the heating is switched off.
