See attached FAQ.  I think it explains the issue and how the unoccupied t'stat setpoint affects this.

Varun,

Thank you for your inputs.

I did change the supply air temp and zone cfm etc using the user defined values and got the confirmation for 1 of 1. But wonder why the software does not hit the target thermostat rather it says 0 of 1 okay!! Maybe I am missing some inputs or this is the case will everybody? And we adjust the points by user defined values?

Regards,
Ananth

Anant,

How much I understand from your sanpshot and questions, is that you just one zone and you are supplying 58 F air to it from the air handler.
>From the limited information I can see here, you might be able to check the following:
1) Supply air temperature to the zone. This may be the reason why you have unmet load hour.
2) Check your themostat set points and throttling range.
3) See the system simulation results (unmet load report) to see that your units is undersized.

let me know if this works, or if it doesnt, would need more information.

1.       Why the zone T-stat check says 0 of 1 OK, can't the software fix this by itself?

2.       When I change the thermostat unoccupied to 85 deg F then this deviation increases to 8.5 deg F!!

3.       The throttling range is 0.1 deg F.
