1. At the furnace control board the Cync Smart Thermostat requires standard terminals (R, G, Y, W, C). If you do NOT have these terminals present, it is possible with some re-wiring of your equipment that the Cync Smart Thermostat can be made compatible.
• The Cync Smart Thermostat does not support proprietary features supported by communicating thermostats, such as a variable fan speed. These features will be lost when using the thermostat.
• The Cync Thermostat requires the Rc terminal. If your system only has an Rh terminal, you will need to wire this to the Rc terminal on the Cync Thermostat.
