I had a contractor do multiple zone pumps with separate thermostats . They made a mistake somewhere and all thermostats control different radiators . How do I fix this problem . Can I put all thermostat control into 1

Sure, you can certainly wire it so that one thermostat controls all zones/pumps. Just have to be familiar with the system wiring and zone control relays/box. However, you could also find the miswiring and correct it so that each individual stat controls the correct zone. This is assuming the boiler was piped correctly, and check valves were installed in the necessary locations to keep one zone from circulating through all zones. If no check valves, one stat control may be your best option. Keep in mind that the single stat you decide to use needs to be located correctly to get maximum comfort in all areas.

Overall, I would suggest having the original installer come back and make the system work like it should. Have you tried this already? If they won't come back and make it right on their dime, they have no business being in the trade, plain and simple.

If you put on a thermostat on a four zone house with separate pumps are they all suppose to heat up

Only the zone that that thermostat controls should produce heat. Unless the other thermostats are turned up also? As I said in you original post, call back the installer. Only way to fix this is to see it first hand. I don't have the time to walk you through troubleshooting a system that I can't see first hand. Good luck and please do let me know how things work out. Either way, this is going to be a job for a pro. Hopefully the original installer was one. If not, hire one.

Thanks for you're reply I wish you lived nearby the guy was a crook . I had total gut renovation in my basement years ago and I added heat in my basement . I tried right away to make him fix it and he would not answer my call. You seem like you know you're stuff . For me I am not mechanically inclined. I definitely need a pro . They might of connected wrong pipes together I don't know. Thanks again . If you are ever in New York area call me . Thanks

Thanks for the kind words. I would assume that in a huge area like New York, there would be many crook contractors. However, in an area that big there is bound to be extremely capable contractors also. I hope you find a good one that can get this all fixed up for you. A good contractor will be able to explain what was done incorrectly, and explain how they will fix the problem. It may be a bit costly, all depending on how poorly the original install was, but it will be worth it in the long run. Please let me know how this all turns out. Take care, and good luck.
