ALRE Radio controlled heating systems – Receivers HTFRL-316.125

Model: HTFRL-316.125 Item No: BA 120800
Equipment: 8-channel radio temperature controller (receiver) for installation inside the heating circuit distribution cabinet; application purpose: heating; 8 relay contacts (make contact)
5 (1) A, max 4 actuating drives per channel can be connected directly (max 32 actuating drives in total), including pump module; ambient temperature -10…50°C; degree of protection
IP 20, protection class II (for protection class I and II complaint equipment) housing, plastic; functions: max 8 time zone possible (i.e. up to 8 clock equipped transmitters can be connected); master-slave operation; emergency mode operation; averaging (up to 8 transmitters can be “learned” per channel+1 transmitter for master-slave operation; radio link status indication for each channel. The top device can, in order to enable the “learning” of the radio transmitters mounted in different rooms can be removed. The power supply is, during this time, ensured by means of a 9 V block battery. The “learning” of the individual transmitters can be realised very easily through the channel selection option in combination with the related “learn” key. Fixing: 4 screws for wall mounting are included in the standard delivery scope – optionally, there is a magnet fixing set (JZ-24) available that facilitates the installation of the device inside the heating circuit distribution cabinet. (implementation of central control using KTFRx) electrical connection: spring cage terminals 0.5…1.5 mm² PG: I
Categories: ,

Description

These radio heating controllers enable, if used in association with alre radio temperature sensors, to realise the control of temperatures in individual rooms. The devices are particularly qualified for application cases in the building reconstruction.

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)
