Information

Block that outputs the zone setpoint temperature (TZonCooSet, TZonHeaSet) and system operation mode (yOpeMod).

The sequence consists of the following two subsequences.

Operation mode selector

The subsequence outputs one of seven types of system operation mode (occupied, warm-up, cooldown, setback, freeze protection setback, setup, unoccupied) according to current time, the time to next occupied hours tNexOcc and current zone temperature TZon. See Buildings.Obsolete.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.OperationMode.

Zone setpoint temperature reset

It sets the zone temperature setpoint according to the globally specified setpoints, the local setpoint adjustments, the demand limits adjustment, the window status and the occupancy status. See Buildings.Obsolete.Controls.OBC.ASHRAE.G36_PR1.TerminalUnits.SetPoints.ZoneTemperatures.

Usage

This version is for a single zone only to be used in the Single Zone VAV sequence.
