New Honeywell Thermostat Install
Hi, I need some help with the settings on my new thermostat.
The thermostat is a Honeywell RTH6500WF and my unit has the below info:
Make: Carrier
Model: CH14NB02400GAAAA
Serial: 0418X90340
Can someone please help me with the following settings?
Select System Type:
0 Heat/cool: Gas, oil or electric heating with central air conditioning.
1 Heat pump: Heat pump without backup or auxiliary heat.
2 Heat only: Gas, oil or hot water heat without central air conditioning.
3 Heat only with fan: Gas, oil or electric heat without central air
conditioning.
4 Cool only: Central air conditioning only.
5 Heat pump: Heat pump with backup or auxiliary heating.
6 Heat/Cool Multiple stages: 2 heat stages (wires on W and W2), 2
cooling stages (wires on Y and Y2).
7 Heat/Cool Multiple stages: 2 heat stages (wires on W and W2), 1
cooling stage (wire on Y).
8 Heat/Cool Multiple stages: 1 heat stage (wires on W), 2 cooling
stages (wire on Y and Y2).
Heat Pump Changeover Valve:
0 Cooling changeover valve: Use this setting if you connected a wire
labeled “O” to the O/B terminal. (I attached the O Wire here)
1 Heating changeover valve: Use this setting if you connected a wire
labeled “B” to the O/B terminal.
Heating Fan Control:
0 Gas or oil heat: Use this setting if you have a gas or oil heating system
(system controls fan operation).
1 Electric heat: Use this setting if you have an electric heating system
(thermostat controls fan operation).
Heating Cycle Rate:
5 Gas or oil furnace: Standard gas/oil furnace (less than 90%
efficiency).
9 Electric furnace: Electric heating systems.
Heating Cycle Rate Stage 2:
3 Hot water or high-efficiency furnace: Hot water system or gas furnace
(more than 90% efficiency).
1 Gas/oil steam or gravity system: Steam or gravity heat systems.
I can attach pictures of the previous thermostat's wiring as well as the new wiring if that would be helpful.
Thanks!

Assuming you have an air handler with heat strips...
0 Heat/cool: Gas, oil or electric heating with central air conditioning.
1 Heat pump: Heat pump without backup or auxiliary heat.
2 Heat only: Gas, oil or hot water heat without central air conditioning.
3 Heat only with fan: Gas, oil or electric heat without central air
conditioning.
4 Cool only: Central air conditioning only.
5 Heat pump: Heat pump with backup or auxiliary heating.
6 Heat/Cool Multiple stages: 2 heat stages (wires on W and W2), 2
cooling stages (wires on Y and Y2).
7 Heat/Cool Multiple stages: 2 heat stages (wires on W and W2), 1
cooling stage (wire on Y).
8 Heat/Cool Multiple stages: 1 heat stage (wires on W), 2 cooling
stages (wire on Y and Y2).
Heat Pump Changeover Valve:
0 Cooling changeover valve: Use this setting if you connected a wire
labeled “O” to the O/B terminal. (I attached the O Wire here)
1 Heating changeover valve: Use this setting if you connected a wire
labeled “B” to the O/B terminal.
*Note: carriers energize reversing valve in cooling mode. If you get heat in cooling mode, this is set wrong.
Heating Fan Control:
0 Gas or oil heat: Use this setting if you have a gas or oil heating system
(system controls fan operation).
1 Electric heat: Use this setting if you have an electric heating system
(thermostat controls fan operation).
**Modern air handlers bring the fan on automatically. if fan doesn't work in heat mode, set it to 1, electric heat.
Heating Cycle Rate:
5 Gas or oil furnace: Standard gas/oil furnace (less than 90%
efficiency).
9 Electric furnace: Electric heating systems.
*Neither, should be set to 3.
Heating Cycle Rate Stage 2:
3 Hot water or high-efficiency furnace: Hot water system or gas furnace
(more than 90% efficiency).
1 Gas/oil steam or gravity system: Steam or gravity heat systems.
*Most likely not applicable. It may show an option for aux heat cycle rate - that should be set to 3 to 5.
I can attach pictures of the previous thermostat's wiring as well as the new wiring if that would be helpful.
Thanks!
