If the zone temperature for a given zone remains more than three degrees from setpoint for more than a user-set time period (default is 60 minutes), the zone no longer votes. For zone controllers with local heat, the time period starts once the local heat is at a maximum. This scenario only applies to occupied operation. In unoccupied mode, the time period is reset. Locked out zones are not counted and therefore do not show up in the current number of Cooling and Heating votes displayed on the Details screen in the Zone Coordinator section on the SBH.
