Yet another Potterton Prt2 Thermostat Replacement Thread

[Thomas Kranenburg]

So I've got a new Z-Wave smart thermostat. Does my wiring look right from my old Potterton Prt2 Thermostat?

Old:

New:

Yet to hook it up. Does this look right?

Does this look right?

I'm afraid, not quite.
Your new stat is designed predominantly for electric underfloor heating - it provides double pole switching, i.e. a live and neutral in, and a switched live and neutral out.
To replace the existing Potterton...
The Red wire in terminal 2 (COM) would connect to 'L' on the new stat.
The Blue wire in terminal 5 (N), would connect to 'N'.
The Yellow wire in terminal 3 (H), would connect to 'Heating L'.
No extra links are necessary.
The Green and Yellow earth wire would be left safely isolated in a separate terminal block.

Thanks for your help. Does this look ok?

So is there no internal heat sensor built into it? I will have to get a sensor connected to top right to get a temperature sensor to it?
