Call the honeywell technical service number listed on the instruction sheet for the thermostat.
They can verify if you have the correct stat for your application and the wires are connected to the right terminals.

Heat pump -> installing digital thermostat.


sounds like the thermostat is not energizing the reversing solenoid , unless you have some experience with electrics i recommend that you call a trades person, to check this problem a multi meter is required and requires the user to know how to work with power , please do not attempt it yourself ...

My heat pump won't cool my house. I have a honeywell rth7500 programmable therostat. It is blowing cool air out of the outside unit and the lines are normal temp.


Warm air should be blowing out the outdoor unit. Have a technician evaluate if the compressor is functioning. There are many reasons why the compressor is not working. One of them being a start capacitor not working. Another being out of Freon due to a leak. Good luck

Have a near new panasonic cs-e28hkr split system air conditioner and the outside condensor fan continously runs even with inside unit is turned off? Thanks


Sir/madam,
If the inside unit (evaporator) is turned off absolutely.
The condensing unit must be turn off outside because the power
are derived comes from the evaporator.
Possible it seems on the cut out stage inside and remain the power still on
Otherwise theres somebody tamper the connection?

Fan cable consist of 3 wires
1 Common line
2 Start /stop line***Change the connection of this wire where it located, To On/ Off switch of the
evaporator inside unit
3 Ground green line/Earth

note: you can get all that wires inside the power supply in evaporator area.

If still under warranty inform the manufacturer

Assumed all the wiring are correct,

to change from manual switching from heat to cool, press [system] button ( left ) to go into system setting.

then press and hold the [fan] middle button untill option display 120

use up down button to select option 300 ( Manual/Autochangeover) ,

Replace Carrier tstatccshp01 builders standard thermostat with Honeywell rth7500 series and wiring not matching Does O wire go to Aux..? fan working but no cool air.


No... Aux. is auxiliary heat strip. This is usually a white or black wire its up to the choice of the installers preferance. O or orange wire. is used to the reversing valve on a heat pump. If you do have a heat pump there is a programing section inside the Honeywell t-stat. which should say heat pump or straight cool, then another section that will ask if you want the reversing valve to energize in heat or cool. most Heat Pump brands energize in cool the exception is Rheem and Ruud they energize in heat.
