Hi out there, I'm new to this forum application and not sure how it will work but here goes. My central heating is a normal 1980's open vented setup with a wall hung boiler in the kitchen, 7 day programmer with separate HW and CH on/off controls below it, a hot water tank , three port valve and circulating pump in the airing cupboard at the top of the stairs, there is a thermostat on the H/W tank, and a room stat in the hall. I found the stat in the hall has been disconnected at some point and the wires have been cut back to the plaster. I now want to install a RF wireless stat to control my CH from a room that gets warm and where we actually spend some time, while trying to work out how to connect the new stat, I found that the wiring has been altered and the circulating pump mimics exactly the burner on/off cycle, ie it never runs unless the burner is on, is this right? I thought it should run on circulating the water until it cools, then the stat should call for the burner for heat etc etc. I have looked up on the interweb and the wiring appears to be a "Y Plan" without a room stat if that helps.
