Honeywell RTH230B thermostat
I am trying to wire a Honeywell RTH230B thermostat.
The existing wires are Yellow, Green, Red and Black
The ports available in the new system are W, Y, G and the Rc and Rh terminals are jumpered.
Which wire do I put in the W port? (Red or Black), then what do I do with the one that is not used?
Help!!
White-Rodgers 1F58 to Honeywell RTH230B
Help if anyone has an idea!
Thanks in advance.
This is for a Ruud upstairs heat pump unit:
The wires connected on the White Rodgers are as follows:
Yellow to the Y Terminal
White to W2 Terminal
Orange to the O terminal
Green to the G Terminal
Brown to the C Terminal
Red to a terminal that seems to be not marked but looks to control whether it is heat, off, or cold selected on the White Rodgers
The RTH has 5 Wires to possibly connect with no clear language on what goes in the Rc/Rh nor any explanation on how to deal with 6 wires connected.
Is one of the wires connected to the White Rodgers a dead or dummy wire or do I put two of them into one of the five terminals on the Honeywell or do I need a 6 wire capable Honeywell?
Thanks again for any insight.
