Evohome connected to 3 Circulating Pumps

[esugrue]

Hi

I have recently purchase the following:

1 x Evohome Connected Thermostat Pack
1 x Evohome Hot Water Kit
2 x Y87RF2024 Wireless Thermostat and Relay Box

I have an oil boiler with 3 circulating pumps circulating the water to the hot tank, upstairs and downstairs. Can someone advise me on a wiring diagram as it is not standard.

Hi,

Wiring would be similar to an S Plan Plus system... The only difference from S Plan Plus, would be that one BDR91 would be the boiler 'switch' for whenever there is heating.

If you are unsure, contact a professional installer!
