Determine Your Heating/Cooling System Type - Honeywell RTH6500WF Wi-Fi Series Quick Start Manual

1.12 Determine your heating/cooling system type

Important!
Heating/cooling system type must be set so that your thermostat
operates properly and does not damage your system.
1.12a If you have a traditional system (natural gas forced air with A/C), your
thermostat is set up by default to control this system.
Go to Step 2
1.12b If your system is:
• Multistage equipment
• Any type of heat pump
• Hydronic
• Other
You MUST change the system type by setting system function 1.
See "Setting functions and options" in the User Guide.
