View Full Version : Voyager Issue

I've got a problem with a voyager rooftop. The supply air temp shows a constant 92 degrees. I changed out the sensor thinking it might be bad but there was no change. Has anyone seen this happen?

do you have electric heat in that unit

haven't seen that one yet. I'll see if the info I dig up on sensors early next week sheds light on it though. I've got a handful of sensors on a tracer system that are cattywumpus, so maybe there'll be some crossover onto your question. we'll see...

Never seen that one yet, good luck. Did you call trane? Let us know what you find. Thanks.

Voyager or Reliatel controls? Either way may be bad sensor. If Voyager then check connection at Economizer module and plug connector in the harness to Economizer module near coil. Prone to corroded connections there.

I would check the analog output source that powers the sensor and see if it is correct. I believe it is 5vdc but would check with voyager troubleshooting guide. Ohm out the sensor wiring to ground and see if there is a nick in the wire inside the conduit. Also make sure the wiring is not connected to a setpoint instead of the actual sensor.

Inplug the harness going to the economizer and see if that helps. I have had problems with econo sensors and boards screw up the whole unit and it wouldn't run. Unpluggung the plug to econo located above filter rack usually should have no effect on ability to operate in heat and cool.If this fixes it, you know where to look!

The last time I looked at that unit, the economizer was not responding to the step test. I'll try unhooking the econ module and see what happens. This unit has voyager controls with Tracer Summit monitoring the operation and it has gas heat. Thanks for all your ideas.

I finally found time to investigate the voyager problem and it turned out to be an incorrectly wired harness connector, apparently from the factory. If this is the case, it hasn't run correctly since it was installed and it took a lowly maintenance/bas guy (me) to discover. This thing must have been built on a Friday?! Thanks for all your ideas.
