I have a Gledhill PulsaCoil Echo system in my new retirement flat which is running on Economy 7. However there is a separate switch in a cupboard which is labelled "On Peak" - should it be on or off please. I have switched all the underfloor heating off on the room switches and have plenty of hot water but the person who set up my Economy 7 timer left this On Peak switch on. I have turned it off - is this OK please.
My 80 year old brain is failing to understand this system.
