I have a taco sr506-exp-4 and 3 of the zone lights are always on but the thermostats are not calling. We already purged the system. Can a taco box work with tekmar boxes?

Lights on:
If the lights are on and the thermostats aren't calling or the circulators aren't running, it is probably mis-wired.0 -
might be thernmostat wiring hole?
1. I had the same problem, but only with one zone.
2. When I drilled holes through the double plate in the attic(I ran the wires through
the attic) it was in the winter. When it warmed up the wood expanded and crushed the
thermostat wires causing a short.
3. Hope this helps? Use an ohm meter to check your wires.0
