1.12 Determine your heating/cooling system type
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.
1.12b If your system is:
• Multistage equipment
• Any type of heat pump
You MUST change the system type by setting system function 0170.
See "Setting functions and options" in the User Guide.
