I have just taken over the HVAC of an Asda store (Walmart) in the UK,
It has 6 Roof Trane Units fitted, EYKD250, they are the first and only Trane units I have come across,
they are connected to and controlled by a BAS BMS system with Tracer Summit interface,
and 1 of the units supply air temperature is showing about 10 deg c lower than the actual temp,
with the manuals I can find there is not enough info to identify the supply air temp sensor or the wiring terminals,
the manuals only show installation, spec and options.
I cannot find a wiring diagram at all. Can anyone help with sensor location, terminal identification, wiring diagram and possibly what ohms I should get across the sensor?
Any help is much appreciated.
