I installed a two zone system over 20 years ago. Two plug-in Taco 006 pumps , one for each zone. Each line voltage thermostats was connected to it's own transformer to run the pumps.

4 or 5 years ago I changed the thermostats to smart thermostats and add plug in transformers for the c wire at the thermostats.

I now want to pull thermostat wire to eliminate the plug in transformers.

Do I need two new transformers? One transformer and a relay? is there a better way than either of those choices?

    This question has been popping up for some time now. First posted about 2 years ago with much less information and by chance not responses

    After you make that expensive repair and you still have the same problem, What will you check next?
