Normally at Dafty Towers I've got three zones. HW, CH_main, CH_annex.
I've been thinking that sometimes it would be nice to have the programmer/stat that controls the main zone to also control the annex zone.
I can see that this would be possible _if_ either I can remove the annex zone valve head (its a Honeywell so not sure?) and then just manually turn the valve to always open. Or disconnect the 240v annex valve head from the JB.
Both of those two require competent people to do and I was hoping there might be a way to manually open the annex zone valve without it triggering the pump/boiler to start.

If you manually push the lever on the MV it stays off but when re-powered the lever moves from the "locked" position back to normal so is no good. I've bought the Regins. Just hope at least one end is safe to leave dangling in the airing cupboard. |

Just hope at least one end is safe to leave dangling in the airing cupboard. It will be fine. |

Do you have the Annex Zone on an independent Programmable Room Thermostat Dafty?

Do you have the Annex Zone on an independent Programmable Room Thermostat Dafty? Yes and it works just be nice for the other programmer/stat to control things some times. |

Occasionally want to put one of the zones into "slave" mode whereby the other zone controls it. I think I figured out how to do it. I set the slave zone controller (annex) to frost mode only so basically off. Then I opened up its MV by moving the lever to manual open. I think thats all I needed. I bought the elgin thing before it dawned on me this might work but no matter its only a few quid and I hate re-wiring MVs that used to pop on a regular basis when they were all Drayton (all Honeywell now). |
