Hi George thanks for your reply. However, as stated in the original question the underfloor heating is separate to the boiler and has its own pump. The stat is wired to the pump. The pump only has a live neutral and earth. So how do I wire it in to the stat receiver?Thanks
Electrician: George Smith, Master Electrician replied 6 months ago
I would try connecting the neutral to N and the live to the Com!
