This is my first attempt at wiring underfloor heating and i need URGENT advice if possible.
The attached diagram is how wired. 2 zone valves, first for central heating with its own stat, second for UFH with three actuators. Actuator 1 is for bathroom with one stat and actuators 2 and 3 are together on bedroom with stat.
Question - FCU is supply at manifold and wiring centre and is only supply in with isolator at boiler. Is this ok or should I have a seperate supply fcu for boiler?
Question - If actuators are called by bedroom stat which then call zone valve will i have back feed on actutor for bathroom?
Question - Volt free contacts on stats so is wiring ok as shown?
Your help with this would be greatly appreciated and please feel free to question my drawing etc if I need to clarify.
