Question Title How do I connect more than 1 UH1 together?
You would interlink the UH1s using three connections:

  • Firstly you will need to connect in parallel all the mains terminals. If this is not possible make sure each UH1s power supply is originating from the same fuse spare. This is for health and safety reasons.

  • Secondly link in parallel all the boiler enable terminals so that each UH1 is capable of turning on the boiler. Type of cable will depend on voltage being used.

  • Finally use two core of a screened cable to link together the Y & B circuits to allow for communications.
