<br />
== Overview ==<br />
Underfloor heating systems use zone controllers and actuators to regulate heating in individual rooms or areas.<br />
<br />
== Main Components ==<br />
* Boiler (or heat source)<br />
* UFH control manifold with actuators<br />
* Zone controller<br />
* Room thermostats<br />
* Pump<br />
* Wiring centre / control box<br />
<br />
---<br />
<br />
== System Operation ==<br />
* Each room thermostat controls an actuator on the manifold.<br />
* When a zone calls for heat, actuators open.<br />
* Pump and boiler are triggered via control module.<br />
<br />
---<br />
<br />
== Wiring Concept ==<br />
* Thermostats send signal to zone controller<br />
* Zone controller activates actuators<br />
* Boiler and pump receive combined demand signal<br />
<br />
---<br />
<br />
== Key Wiring Points ==<br />
* Actuators may be 230V or 24V (must be confirmed)<br />
* Each zone must be correctly assigned<br />
* Pump and boiler interlock via controller output<br />
* Keep low voltage and mains voltage separated where required<br />
<br />
---<br />
<br />
== Common Fault Areas ==<br />
* Incorrect actuator voltage mismatch<br />
* One zone not heating (failed actuator)<br />
* Incorrect thermostat pairing<br />
* No pump operation on demand<br />
* Wiring centre misconfiguration<br />
* Airlock or hydraulic issues mistaken for electrical faults<br />
<br />
---<br />
<br />
== Notes ==<br />
* Always confirm actuator voltage before replacement.<br />
* UFH faults are often mixed electrical/hydraulic issues.</div>Morgan Allen
