Hello, Apologies not been here for a while! Hoping to pick your brains, I am working on an ideal vogue combi and the customer wants to have two zoned heating circuits controlled via two nest thermostats but I can't seem to find a wiring diagram from Ideal. I have spoken to Ideal and three different technical guys have given me three bits of conflicting advice! One said to do an S plan, but didn't have wiring guide and couldn't help, the second said s plan unnecessary and still couldn't help with wiring and third one told me that the vogue has two wiring thermostat links internally but would still need to control the two zones. So as you can imagine I'm a bit confused, any advice would be great. Many thanks, Lee.
