I require to replace a mechanical variant made by Process Control Gear, St Albans.

Can anyone recommend a reasonable priced replacement please.

The existing item has five connections marked as follows: -

E = Earth

2 = Cooling (not used in my set up)

1 = Heating (has a yellow covered wire connected)

N = Neutral (has blue covered wire connected)

3 = Line (has a red covered wire connected)

It appears to be mounted on a backing plate.

Regards

this is an industry standard configuration and almost any stat can be used in place of it.
