Please could someone explain the layout of our planned heating so i can try and work out a potential cabling issue.
We have 2 zone heating installed. Ground and first floor.
The plumber installed 3 honeywell motorised valves near the boiler. 2 for central heating and 1 for hot water. These are not yet connected.
Questions.
1. There is a black cable coming out of each motorised valve. Where will this connect to? To the boiler or the programmer? The programmer will be installed on the lower floor so will we need to chase 3 cables from the valves to the programmer?
2. I have been given different advice on whether to install a 2 channel programmer and use thermostat to differentiate and control the heating in the 2 zones or get a 3 zone programmer such as Horstmann H37xl and have the ability to time each zone eg at night etc. Plus thermostats.
What is the sensible option?
Are Horstmanns as good as Honeywell?
