| Nuances and Criterion Verified While Applying a Named Schedule

The system checks for a few nuances and criterion when trying to apply a named schedule to a zone, Only when all the criteria are met the system let the user to apply the named schedule.

Following are the criterion that are verified while applying a Named Schedule. 

• The desired temperatures set for named schedule, must be within the Building desired temperature limits.
• The Schedule duration set for named schedule, must be within the Building schedule duration limits.
• The deadbands(cooling and heating ) for the named schedule, must be the same as the deadbands used for the module
• There can be multiple entries in a named schedule but the entries can't overlap with one another. If any user created an entry for a specified time period, then another entry within or overlapping that period cannot be created

Even if one of the criterion is not met a warning window is displayed as below.

Desired Temperature Warning

In this case the named schedule applied is outside the desired temperature limits of the building.

The system does not allow you to apply the named schedule.

You can only go back and edit the named schedule to apply.

It should be noted that the Desired temperatures in a named schedule should be within buildings heating and cooling user limits. Each zone can have its own desired temperatures which will be within user limits of that building. If desired temperatures as in the named schedule are outside the desired temperature limits of the building, then there will be an error message and user can't apply it. In such a case, the named schedule will not be applied and will remain the previously applied schedule.

Deadband Warning

In this case the cooling deadband is a named schedule not the same as that of the module.

The system does not allow you to apply the named schedule.

You can only go back and edit the named schedule to apply.

It should be noted that the Named schedule will validate the dead-bands of the zone to which it is applied. If the dead-bands in named schedule is equal to or more than that of the zones dead-band, only then it will be able to apply the Named schedule to that zone. 

Changing user limits with tuners

In case a named schedule is applied to few of the zones but from the tuners user tries to change the building level user limits or deadbands and if its outside the named schedule then it will give a warning message stating "Named Schedule is having desired temps which is outside the new tuner limit". In such a case, the user will not be able to edit the tuners and has to move back to the named schedule to change or edit it to a different schedule.

Changing user limits with Master control option

In case a named schedule is applied to few of the zones but from the Master Control user tries to change the building limits or heating and cooling limits and if its outside any of the named schedule then it will give a warning message stating "Named Schedule is having desired temp which is outside the new heating or cooling limit. Please either change the user limit or remove the named schedule from these zone." In such a case, the user will not be able to edit the master control and have to go back to the named schedule to change or edit it to a different schedule.
