Hi, I am the owner of a recently installed HP system and my installer is having some issues answering a what I consider a simple question
Thermostats: AUBE TH146-P
HP: Trane 16XLi 3 tons
air handler: Trane TAM7 (TAM7A0C42H31SB) equiped with 20Kw electric heater (BAYEVBC20BK1A)
The question: is my system considered a 3heat/2cool or 2heat/2cool, the question is asked because my installer is having a challange on how to set my Thermostat. Right now it is set for 3H/2C with interstage delay at 5 minutes.
Jumper between w1 and w2 has been removed
symptom now is that when heating Y1, Y2 and W1 are coming on even when set point and ambiant temperature are close.
