The fans in the other zones are working properly. It's zone 5 not working. The fans are not coming on. I installed a jumper wire and made the fans operate by by-passing zone 5 thermostat. With the jumper wire the system runs all the time.

Own a 2005 Monaco Dynasty with a Aqua Hot system AHE-100-03S. When I turn the Aqua Hot on to heat the coach, the front blowers for zone 5 are not working. I've checked the boiler antifreeze and the system is full. I believe the Aqua Hot is working properly. I think it may be the coach thermostat system. I checked the zone by removing the 2 wires that go to:#5 THERM -O#5 THERM. The red light went out, then I installed a jumper wire between#5 THERM -O#5 THERM to force the zone to run, with no red light. Now zone 5 runs continuously because I removed the thermostat from the circuit. Has anyone experienced this issue? I've talked to Roger who is the Aqua Hot expert but he believes the system is working properly and it may be the coach. Thank you for any advise.
