Re: Thermostat Issue

Unless it's a B valve, you're going to want to energize it…

Remove Rc Rh jumper

Wire heat circuit to Rh and W

Program thermostat to AC only in the installer menu 05

That should give you the result you want. No special relay or wiring needed.

Even MacGyver can do it the regular way when it is appropriate.

If they don't want to use the heat pump for heating at all, just set up the thermostat as conventional & jump the reversing valve and the compressor call together, or just tie the reversing valve on to the R to avoid the sounds it makes when it throws. I think someone mentioned the same thing earlier, but this is all my idea.

2 thermostats is the least invasive, and MacGyver doesn't get involved. You said "Door #3, but the heat pump might help when it gets really cold. Is this your radiant design and install? Wondering why the heat pump if it's only used for cooling. Rebates?

Re: Chimney condemned; wood stove conversion question

I would definitely get a second opinion on that chimney.

But no, just putting a screen over the exhaust from a wood stove isn't going to fly. That is NOT a safe option.

Set the heating circulator to "LOW"…………it is currently on "HIGH". Very simple. This will slow the flow rate and raise the DT so the return water is cooler. You are looking for 15-20F for a difference between supply and return. Don't listen to them if they claim it won't work.

(Leave the circulator for the indirect on "HIGH".)

Re: Adding Hydronic Loop Before HX?

sorry everyone I see I left out some critical detail. It is my assumption HX is to isolate very old radiant floor, likely non oxygen barrier pex. Bosh boiler is not a combi (PN is on schematic but it is KBR 21-3)

Re: New Boiler - Radiator Screaming

Anyone heard from OP? I would like to hear how things are going.. New here and I posted once a few months ago but resolved my problem. I've been interested in OP's plight and all the great information on here.
