Triangle Tube Indirect Tank: DWH Sensor Shorted...
Heating Pros, Just put in a warranty replacement of a TT Smart 40 Indirect tank. After filling everything up, I turned it on, and the boiler shows "DHW Sensor Shorted".. I've inspected/tightened the only TWO wires that go into the sensor area on the tank.. I even looked at the factory side of things, but all looks good/tight there. Any thoughts? Could it be a bad sensor? Is there a way to run this without the sensor from the boiler, just using the thermostat in the tank itself? or is that a bad idea? THANK YOU!
