Notes
• Thermostats that close contacts "O" or "B" during Cool or Heat call only have not been verified. "O"
and/or "B" contact closure must be maintained during respective cycle / mode selection.
• IDU Fan logic, depending on model selected, may delay IDU fan operation momentarily during a cold
start heat call. This function allows IDU coil to warm up prior to operating fan in some IDU models.
• Thermostats that use resistive anticipation are not supported at this time.
• Verify documentation of desired thermostat so that the logic is same as shown in the table above.
