Y1 W1 Wire from older Honeywell to new RTH honeywell
My older Honeywell programable thermostat for my heat pump went bad, I purchased a new RTH 7000 series thermostat. All of the wires are right on from the old one except the Y1 W1 wire. This wire was connected to the Y1W1 in the older thermostat Where do I connect it to the new thermostat? Any assistance would be greatly appreciated.

Leave the factory jumper between R & RC. Connect the wires to the new stat just as you have them labeled. Use a piece of thermostat wire to make a jumper from AUX to E terminals. Your new thermostat should give you instructions on how to access the installer set up. You are going to set it up as heat pump with aux. I see this is 2 days old but if you need any help let me know.
Hello You have only 5 wires? multi stage if so ,is run by something else.Check that RH/RC is jumped out on new stat.Also check that O is not on the B terminal.If there is an A/B select switch set it to O.Emergency heat button dont matter as there is no wire to run it with only 5 wires.
This is a Focus Pro 2 heat,2 cool thermostat. If you are connecting this to a single stage(1 heat) residential furnace then your connections are: At the thermostat the R and Rc therminals are internally connected so you can connect your R terminal wire from the furnace to the R terminal at the thermostat(this is your 24 volt supply for both heating and cooling. The W or W1 wire (heating) from your furnace you connect to the W1 terminal at the thermostat. The W2 wire from your furnace(if your furnace is a 2 stage furnace) you connect to the W2 terminal at the thermostat. The G wire from your furnace(indoor fan) you connect to the G terminal at the thermostat. The Y1 wire(cooling) from your furnace you connect to the Y1 terminal at the thermostat. The C wire(common or neutral) from the furnace you connect to the C terminal at the thermostat.
The proper way to do it would be to use a small piece of wire stripped at the ends. Then use a small amount fo solder on each end to connect RC to RH. Or use a small piece of solid(stiff) wire and strip the ends. The wrap the ends around the connector and crimp them to make contact. I would not use a paper clip. A paper clip is not designed to carry 24volt current and could melt.
sounds like you have a heat pump the w2 on old thermostat is for a second stage heat. If you can give me a little more information on type of system you have (forced air furnace with heat/cool, Heat pump or boiler)? How many wires are on old thermostat? Is it a no programmable or programmable? How old is the furnace?
