Hello All,
Quick question for you. How are the total run hours summated in the SS-R
reports? I have two models baseline and proposed with the same fan
schedules however the run hours are different. I was under the
impression that the run hours are directly related to the times in which
the fans are scheduled off/on. Perhaps this is still the case and
something else has been altered between my runs. Thank you for the
clarification.
Regards,
Connor
Connor,
In addition to the fan schedule, the total run hours are also affected by the 'Night Cycle Control'. Please check if the baseline and the proposed building models have the same night cycle control.
Even if the fans are set to cycle on during night time in both the models, the total run hours can be slightly different due to differences in building envelope. e.g. the proposed building might have a well insulated envelope and may not call for heating during night time to maintain the thermostat set back. Whereas, the baseline building (or a zone in the building) might call for heating during night time and thus would result in the fans cycling on during night time.

Dear All,
I am working on some parametric runs and cannot go beyond the fist simulation.
The error that I get is "value beyond allowable range".
Does anyone know what is the allowable range and for what?
I have worked on eQuest before and this has never happenned before.
Any help will be greatly appreciated.
Thanks,
Ruju Rathod
Hi Connor,
Go To:
help-> tutorials and references -> Detailed Simulation Reports Summary
If you search for the SS-R report it says that the run hours are based
on the flow hours only. Therefore I am assuming that your fans are
running differently during their "off" time due to the "cycle on any"
fan control.
Cheers,
