ALRE Radio receiver for installation in the distributor socket HTFRU-110.124

Model: HTFRU-110.124 Item No: BA 110201
Equipment: 1-channel temperature controller (receiver) for flush-mounting in a distribution box. Switching capacity: up to 30°C ambient temperature: max 2300 Watts (max 10 A), protection rating IP 20 with correct assembly, protection class II with correct assembly for protection class I and II complaint equipment, housing PC, pure white (similar to RAL 9010), electrical connection 0.5…15 mm²
The HTRFU-110.124 can be combed with a radio controlled room temperature sensor with reference valve setting function to regulate an (electric) underfloor heating system. To enable this, the controller has an input for connecting an optional remote sensor (HF-8/4/K2 or HF-8/6 K2)) which sunk into the floor. When used in combination with this sensor, the following modes of operation are possible: floor control or room temperature control with floor monitoring and direct or central setting or reference temperature (central control)
If you do not use the remote sensor, the HTFRU-110.124 operates as a room thermostat with direct or central setting of the reference temperature (central control) PG: I


These radio heating controllers achieve the control of temperatures on an individual room basis, if used in association with our radio temperature sensors. The devices are particularly qualified for application cases in the building reconstruction sphere.

Technical Data  
Operating and Switching Voltage: 230 V ~, 50 Hz
Switching Difference: Approx. 0,5 K (room control)
Receive Frequency: 868.3 MHz
Indications: Three-colour LED indicator, with devices with several receive channels there exists one indicator LED each per channel (indication of the “learning” mode, of the correct functioning of the radio connection and indication of a radio link loss). In addition, the associated channel(s) can, subject to the existence of an established radio connection, be indicated in retrospect by actuating the “learn” key at the transmitter.
Protection Class: See equipment
Admissible Air Moisture: Max. 95% r.h., non-condensing
Storage Temperature: -20…+70°C
Safety and EMC: Acc. to DIN EN 60950-1

And DIN EN 300220

Housing Material: See equipment
Electrical Connections: See equipment
Failsafe: In the event of a radio link loss, all receivers change over to emergency mode, Power-on time 30%

(approx. 3 min on, 7 min off)
