Trane expert WSHP GEHB048
Does anyone know the model number of the ZSM with a set point only? Also the main board has only one LED w/ no test pins. Seeing no fan op, steady Green LED.
There are no occupancy switches on the b-13 digital inputs. Any help is appreciated.

Is it 24v controls or a ZN controller?

It is Tracer ZN510 or 524 with a baysens 006B ZSM.
My question is, can I get a list of the current diagnostics thru an LED blinks code or do I have to sic "Rover" on it. The literature on the controller and the unit IOM is vague.

Depends on which wires are hooked to the 006.. 1&2 are your sensor input 3 is your mode 45678 etc are system faults.. You will get voltage errors on ltb you can read with meter...

check the board incoming and out going voltage disregard the LED

I work for Trane and I work on ZN boards all the time. If you are having problems with ops I would first connect with Rover to see your diag., settings etc. If you dont have Rover I would push the service button for 5 seconds and wait, then push it again and again...this will cycle the unit. Fan, reversing valve, compressor and so on. Hope this helps. GL and be safe!
