Hi there,
I just bought a Hive Active Heating to replace my Honeywell CM900 thermostat (R6660D) linked to myVaillant Combi boiler ecoTEC plus 937.
I would like some help re wiring my new Hive thermostat. At the moment I have a blue cable wired onto the N, red cable wired onto the first L, a black cable going from the second L to A and a yellow cable wired onto B. See picture attached.
I guess the blue cable will now go onto the N (Permanent Neutral) connection on the Hive, the red cable onto the L (Permanent Live) connection on the Hive.
Where I am confused is where to wire the black cable and the yellow cable onto my Hive. (1. Common, 2. Heating off, 3. Heating on or 4. Unused?
Would really appreciate your help
