NT HEATING CONTROL 1 Description and Function Many heating systems including the circulation pump operate continuously regardless of the actual heating demand of the building and are therefore energy inefficient If a HouseHeat system is installed comprising of Wireless Room Zone Thermostats and Wireless Valve Motors the addition of a FHT 8W BoilerConnect unit can boost the energy efficiency of the system still further by offering a solution to the problem of the boiler and pump operating continuously BoilerConnect evaluates the data transmitted wirelessly between the room thermostats and the valve motors for up to ten rooms zones and is able to regulate the heating output of the boiler to precisely match the actual heating demand of the building increasing the energy efficiency of the heating installation The switched output of BoilerConnect may be either connected to the burner control of the boiler and or the circulation pump In automatic mode BoilerConnect compares the transmitted data from the Room Thermostats percentage opening of radiator valves to a freely programmable threshold value on a minute by minute basis and switches its output relay on or off correspondingly Manual switching by the user is also possible BoilerConnect is able to monitor wireless data communication between the FHT 80B Room Thermostats and FHZ 1000 HouseMaster if installed and FHT 8V Motor Valves i e all HouseHeat system components BoilerConnect is
