Dear Anil Misra,
I don't think you can define a fortnightly schedule in Prebid. You can
only have weekly and daily schedules so Prebid (or more exactly Type56)
has no way to distinguish between "one Monday" and "another Monday".
A weekly schedule actually switches between different daily schedules
according to the day of the week, which could be seen as "multiplying"
schedules. If you need to add the effect of an ON-OFF schedule to a
variable setpoint, you can use one schedule for the temperature setpoint
and another schedule for the maximum power. Using a very high setpoint
for cooling or a very low setpoint for heating will of course give the
same results.
Creating schedules in TRNSYS (and using inputs to Type56 rather than
"internal schedules") will give you more flexibility, at the cost of
more connections in the TRNSYS project.
I hope this helps,
Michaël Kummert

Dear trnsys users,
I want to define a fortnightly schedule of the setpoints for a cooling
system attached to a building. At the same time, the system has to be
switched off in the night and during weekends.
I need to know how this can be scheduled. is there any possibility to
multiply two schedules in prebid or this has to be done somehow in the
dck file.
Please help me if someone has already used a trick to achieve this.
Thanks
