HTRRB-011.010
Underfloor temperature controller with remote sensor, surface-mounted, 10-60…°C
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.
