Zone valve wiring taped to boiler pipe
I have a newly installed Peerless boiler. *The HVAC installer used a TACO zvc406 *six zone control panel and Honeywell zone valves. **From the start the control did not function properly. *Zones were receiving heat
without requesting it. *He came out yesterday and said that the Honeywell zone valves and the Taco control panel didn't work together so he rewired the zone valves outside of the control panel. The control panel now has one wire from all six zones and no longer has functioning indicator lights. *I now have a spaghetti
tangle of wires that he taped to the *main hot water pipe that the zone valves connect to. *Is this safe? *I've never seen wires taped to a hot pipe before. *Am I being ripped off?
