Setting Schedule Hold

The schedule hold menu is used to set a permanent hold on the internal scheduling or resume the schedule. The permanent hold is typically used for non-scheduled events that extend for long periods of time.

Note: The Override Schedule function is available in T600HPN-3 models only if DI1 or DI2 is configured for remote NSB.

Note: The Schedule Hold menu is also displayed if DI1 or DI2 is configured for remote NSB.

The following selections are available in the schedule hold menu:

• Permanent Occupied Hold (occ hold): This selection puts the thermostat into a permanent occupied state via the occupied setpoints. Occupied hold appears in the Status Display Menu when this selection is active.
• Permanent Unoccupied Hold: This selection puts the thermostat into a permanent unoccupied state via the unoccupied setpoints. Unoccup hold appears in the Status Display Menu when this selection is active.

- Resume: This selection cancels the permanent hold and enables the regular program schedule.

To enable or cancel the permanent hold feature while in the Main User Menu:

1. Press the NO key to all prompts until the schedule hold prompt appears on the display. Press the YES key to set the schedule hold type.
2. Press the UP/DOWN arrow keys to locate the desired permanent hold type (or resume schedule). Press the YES key to enter the selection.
