The electronic floor temperature controller HTRRBu110.021 is suitable for time-dependent regulation of temperatures in enclosed spaces. It can be used for underfloor, perimeter, bathroom, ceiling, tiled stove, marble, and wall heating or temperature control systems up to 3000 W. The controller can be used as a master (pilot controller) for reducing the temperature of other controllers, with controllers from the FETR, FTR, and RTBSB series being suitable as slaves (satellite controllers). Operation is via direct selection buttons. In case of sensor breakage or short circuit, the heating is controlled with a duty cycle of 30% to prevent cooling down or frost damage in the room. Temperatures below 20 °C are also interpreted as sensor breakage, triggering the emergency operation function. Installation can also be done on a flush-mounted box using an adapter plate.
