How do I connect my boiler to my Heatmiser?
Switch on the power supply, the power LED will illuminate. On the RF-Switch, press and hold the Boiler pairing button for 5 seconds. The Boiler status LED will switch on. Press and release the pairing button on the UH8-RF.
What does a wiring Centre do?
The wiring centre is where all the wiring for a UFH system meets. It is fed by a 230v fused-spur supply and coordinates the signals received from each of the heating thermostats.
Why is underfloor heating not working?
Trapped air is the most common problem with a malfunctioning underfloor heating system, especially one that uses hot water flowing through sub-floor pipe work. This pushes water in the pipe, but too quickly, and traps air at the same time. When you fill your system, ensure the water is flushed through the pipework.
What is a manifold in underfloor heating?
Manifolds are used in underfloor heating systems to control the flow of water through the system to provide an even, comfortable warmth across the whole floor. The manifold acts as the hub of a heating system connecting both your supply and return lines in a central place.
What is wiring Centre underfloor heating?
An underfloor heating wiring centre makes installing your underfloor heating system a breeze, simplifying the wiring process. The actuator, boiler and pump connections are all wired from a single point using the wiring centre. Wiring centres are suitable for wet underfloor heating systems.
What does the end switch do on a zone valve?
End switches in each zone valve control the central circulator and the burner. On a call for heat, the valve is opened. When it reaches the fully open position, the end switch “makes” (makes contact), causing the aquastat relay to pull in, starting the circulator and the burner.
What is the white wire for on a 28mm zone valve?
The white wire (28mm Valves) becomes live when the valve closes, it is not used and is wired to ‘spare’ terminals for safe isolation.
How is a UH1 connected to a boiler?
TO OTHER UH1’S IF FITTED Y B TO BOILER ENABLE LS LR TO BOILER ENABLE LS LR Wiring Diagram – Connecting Multiple UH1’s Wiring The UH1 Using BELDEN 9538 cable on the Heatmiser Network When using this cable make sure the shield drain wire (the silver unshielded wire) is connected to earth at the UH1.
What do the DIP switches on a uh1-w mean?
ENGINEERS TEST SWITCHES UFH = UNDERFLOOR HEATING ZONE RADS = RADIATOR ZONE N.B. RADIATOR ZONES DO NOT ENABLE THE BOILER UNLESS THE VALVES ARE WIRED AS SHOWN You can use the dip switches to test the outputs on the UH1-W without having to pair the thermostats. This will show if the actuators, valves/pumps on the system are working correctly.
What kind of network do I need for Heatmiser?
For the Heatmiser network you should use CAT5-FTP – This is SHIELDED CAT5 OR CAT5E FTP stands for foil screened twisted pair The network uses digital communications to talk between the thermostats and Touchpad or NetMonitor (+).
Do you need warranty for uh1-w wiring centre?
Wiring CentreModel:UH1-W This equipment should be installed by an appropriately qualified / registered electrician. Ensure all wiring is correct before applying power. The warranty does not cover any damages caused by incorrect wiring and installation. Want More Information?
