Lennox thermostat with Honeywell RTH7400
Replaceing Lennox thermostat with Honeywell RTH7400
--------------------------------------------------------------------------------
------------------------------------IF I CONNECT THE O THEN WHERE WILL THE W1 GO--------------------------------------------------------------------------------------------------
I am replaceing a Lennox 51H4001 with a universal Honeywell RTH7400 5-1-1 thermostat.
The wires from the old thermostat were labeled C, G, Y1, W1, O, RH
The replacement thermostat has the w1 and the o going to the same place - I connected w1 and taped off the o.
HONEYWELL THERMOSTAT WIRING
C ---------- W2/AUX
G ---------- Y2/E
Y ---------- L
O/B/W
RC
R
The R and RC are connected to each other and I connected RH to R
The directions did not give an alternate wiring example for a O wire and a W1
This is for a Lennox Elite Series Mod# HP26-048-7P Heat Pump
The heat is working fine but the air is not.
Could someone please help with the correct wiring instructions for this unit.
Thank You
I DID READ THE INSTRUCTIONS -
Page 11 does not show a w1 and o - neither does page 12
If the instructions were clear in the book I wouldn't be on here trying to figure it out
The instructions show both wires going to the same location in different wiring examples - and page 11 is for conv. Systems not heat pumps - heat pump is on pg 12
