Potterton 80e

[lloyds999]

I've got a Potterton 80e (about 10 years old) with all TRV's and a Honeywell HW & CH timeclock. I want to fit a Honeywell CMT927 wireless roomstat as well.
Does anyone know the boiler connections please?

Thanks
Gerry

Hi Kev'
Ref' "l and swl" ....is that a lower-case "L" or a number one ?
Are these terminals marked as this on the boiler pcb?
Thanks. Gerry

Also Kev...
I don't want to over-ride the timeclock I just want to shut the heating down when temperature is reached.

 

[kevplumb]

thats why you wire it in series with the clock
