Hive install hot water valve

[wilie1ker]

Hi all I've come asking some advise on my hive install, installation went ok, traced thermostat wires back to central box an disconnected heating side off things works fine,but the water would not work the boiler didn't kick in, so after a bit off testing with a multimeter, block 3 when turned on became live, so I moved the brown from the water valve from block 5 which comes from the water tank to block 3 and this seams to work, just not sure if it's correct

Sorry no idea - my crystal ball isn't working at the moment
Is this S-Plan, Y-Plan, something else ? What wires go where ?
Looking at what's there, it does look like an S-Plan system with 2 zone valves. From the description, it sounds like terminal 5 is the thermostat switched live from the tank stat - and that is where the valve brown wire should be connected to. When you say "switched on", I'm assuming that when you set the timer to on for the hot water, terminal 3 is live ? But that's only a guess - you'd have to trace the wires and work out what's connected to where to be sure.
Disconnecting the room stat should not affect the hot water on an S-Plan system - if it does then either it's miswired, or you've dislodged/disconnected something you shouldn't have.

Is the valve for the heating system connected to terminal 6 ? If so, then what is connected to the right hand side of that terminal ?

Hi SimonH2 sorry for the lose description i believe it is an Splan
Above is the wiring before I started.ill take a look at the wiring and reply

Yes Simon in my first post all the wires to the left comes from the heating and water valves, the wires that's been removed on the right I've traced them back to the thermostat that I've removed the hive heating worked fine once installed, but the water when on did show green on the hive receiver but the boiler would not turn on, the brown from the water valve was connected to block 5 that goes directly through the wall were the tank is but when I called for water only block 3 becomes live , from the wiring diagram s I've looked at some off the wiring seams off

2 brown wires originally in block 4 one from wired thermostat that has been removed, the other from programmer was moved to block 6 were the brown heating valve wire is on left, this was originally the switch wire from wired thermostats

a. where is the cylinder thermostat connected
b. if the cylinder was hot, the thermostat on it will prevent the boiler from working.
c. on S plan, heating and hot water are entirely separate items, changing the wiring for one should not affect the other.

The hot water should be completely independent of the Hive - or does the Hive also control the hot water ?
To get any further, you'll need to draw out the connections on a sheet of paper - then it should become obvious what's wrong.

Thanks all for the help, after tracing the wires back I relised that brown from the water valve should have remained in block 5, just wasn't giving the tank thermostat time to send a request back to open the water value, all's working great now
