FHT 80B Wireless Heating Control System

Highlights & details

  • Slave function
  • Controls up to 8 actuators
  • Simple operation
  • Quick installation


The FHT 80B Wireless Heating Control System is used for temperature control in individual rooms in which the heat that dissipates from radiators is controlled by reducing the flow of hot water in the heating system. The ‘FHT80B’ heating control measures the room temperature by means of an integrated sensor and transmits the corresponding control data to the ‘FHT8V’ valve operating mechanisms.
The ‘FHT80B’ can analyse the status signals (window open/closed) of up to four ‘FHT 80TF’ (646463) door/window contact sensors and, in order to save energy when a room is aired, for example, automatically reduce the temperature down to a so-called ‘Window open’ temperature, when the room’s window is opened. The ‘FHT80B’ also facilitates a bi-directional radio connection with the ‘FHZ 1000’ (617500) home radio central unit.

Included in delivery

  • Thermostat
  • Wall mounting set
  • Batteries
  • Instructions for use

Any other use of the heating control (for example, in cooling systems, floor heating systems, and so on) is not permitted and may lead to serious damage.

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Fully Automated Central Heating I have automated my central heating system, which previously had just two time+temperature controlled zones - upstairs and downstairs. Using 8 FHT80B Radio Thermostats and some 25 570056 Actuators (a big house with 28 radiators) and an FHZ 1300 Radio Home Control Centre, I can now control separately and independently eight areas of the house with a considerable saving in heating oil and improved comfort. The Radio Thermostats (being battery operated and wireless) were easy to install (no wiring) and to programme. The actuators simply replaced existing thermostatic valves and provide, together with the Radio Thermostats, far more accurate control than the simple thermostatic valves they replaced. Each of my 8 zones have their own temperature and time settings. The FHZ 1300 is a radio transmitter/receiver that plugs into a PC and talks to the FHT80Bs so that I can quickly reprogramme some/all the Radio Thermostats from my PC. e.g turn on the heating in the guest bedroom and bathroom, to come on at 6:30 am at 20C and go off at 8:30 am. The system works and is very cost effective. Indeed, I couldn't find a similar competitor. The only disappointment was the FHZ 1300 PC software - its facilities are basic and it is in German (no English headings, etc.). The Radio Thermostats and Actuators appear well made and designed and are easy to install and use and can be deployed without the FHZ 1300, which is only of benefit if the system is large, say, 6 or more Radio thermostats. Then each Radio Thermostat has to be individually programmed (without the need of a PC). The only niggle I have with the Radio Thermostats is that they display the temperature set, rather than the actual temperature of where the Thermostat is located, but the two of course should be the same after the area warms up. 04 February 2011
