alright im having problems again.
trane m/n: tch480a4 s/n: co5m11663
morning startup ambient about 64-69 deg F. seems like the economizer is keeping the unit from starting mechanical cooling.
i want to completely disable the economizer system in this unit. and make it a cooling only unit. we dont need it here in hawaii. also theres a co2 sensor installed.
i was reading on another post if i remove the main plug or ma sensor it will disable the economizer. anyone know if this is true?
this is the vav/vfd horizontal discharge unit.
sa setpt 52 deg oa setpt 50
morn. warmup 0 static setpt 1.5in.
