Hi,

I have just installed a new Drayton zone replacement valve , model ZA5.

The good news is that the value is working; however, the issue I'm experiencing is that when my thermostat turns the central heating on, the valve moves to the off position and the valve closes and when I turn off the central heating from the thermostat the valve moves to the on position and the valve opens.

I have a hive thermostat already installed.

Any idea what's happened and how I can fix this?

I've tried my best to place the wires in the exact same place where I removed the old value wires but as you will see the wiring/control centre is a shambles.

Please let me know if you require more pictures or information.

Thank you

Meethi

Is that valve actuator available as normally open power closed? (I had a Honeywell one once in the wrong box!)
