Hello
I am replacing a non-programmable thermostat with a programmable model. I am asking for advice about how to wire the new thermostat. The included instructions are not clear to me and I don’t want to damage anything by connecting it in the wrong way. I have included as much information as I thought was relevant.
My heating/cooling unit is a TRANE XR-13 2TWR3030A1000AA which is a heat pump with emergency heat. I have six wires currently connected to my Totaline thermostat:
Current setup: Totaline thermostat
S1 – no wire
S2 – no wire
O/W2/B – orange wire
R – red wire
C – blue wire
Y/Y2 – yellow wire
Y1 – no wire
G – green wire
W/W1 – white wire
I bought a programmable thermostat with the following connections: Honeywell TH6220D1028
Connector labels:
(conventional/heatpump)
No label/L
Y2/E
W2/AUX
G/G
W/O\B
C/C
Y/Y
R/R
Rc/Rc
I need help with the yellow, orange and white wires. Here are my specific wiring assumptions and questions:
Red wire from R to R/R
Blue wire from C to C/C
Green wire from G to G/G
Orange wire from O/W2/B to ???? (W2/AUX or W/O\B)
Yellow wire from Y/Y2 to ???? (Y2/E or to Y/Y)
White wire from W/W1 to ???? (W/O\B)
Thank you for your help.
