Replacing thermostat for central heat and air/ not humidifier

Need to replace Honeywell chronotherm III 8601D, wiring slightly different on new Honeywell Both are 5 wire but new one has rc and rh plus Y, W, and G. Old has Y, W, G, and R ( which is empty) and Rh connected to red wire, and C connected to blue wire . Do I just connect the C (blue) to the Rc and the Red wire to the Rh and connect the rest as same as old? Or do I need a different thermostat?

I have a Honeywell Chronotherm III Thermostat and in instead of showing the temparature in the display it shows -AC. I've replaced the batteries, and tryied adjusting Temp up and down for cooling and...


It would appear to me that you have lost the 24 volt power supply to the thermostat. In referencing the manuals for this thermostat, available @ www.honeywell.com, I've found that when the thermostat is not connected to the wall plate (plate mounted on the wall, that the thermostat either snaps or screws into), it will display the -AC. This being said, either the thermostat is loose on the wall currently, or your 24 volt transformer has died. Hope this helps.

Chronotherm Three thermostat vs Buderus Logamatic Computer.


The outdoor thermostat senses the the temp of the outside air, and adjust the boiler water temp according to what it knows is best. The reason that the boiler is running longer is the old boiler used to be constantly sending 180ish degree water to the baseboard, now that water may only be 140ish degrees. The idea behind this is to reduce off cycle heat loss, as the greater the temp difference between the air temp and water temp, the quicker you loss heat. The theory in boiler run time is this, the less times it starts and stops, and the long run times will give you the best efficiency. Hope this answers you questions.
