Dear Jeff,
Hi again. Currently it is working. I
defined the Number of profiles for each day to be 2 in the
parameter part of the type 41. Then, it has stated to operate
between specified points.
That was the key part. Thanks for your
help.
I have an other question about my Project
for type 56 building model. Although everthing seem to be
normal for airnodes such as temperature, relative humidity,
the sensible and latent energy demands of the airnodes (the
outputs of type 56) equals to always zero. Should I define
something special here? Do you or does anyone have an idea
about this case ?
Thanks in advance.

Dear Jeff,
Thanks for your help. However, type 922c
operates always on althogh I defined the types 14 and 41
together with the type 108 signals outputs by using an
equation. Than, I connected them to conditioning signals of
each 5 stages.
Can it be beacuse of proforma definition
for type 41?
Regards,
HG OZCAN
If the control signal to the equipment is a
function of both time of day/ year and a thermostat then the
input should reflect that. Use an equation and multiply the
on/off signal from your forcing function by the on/off signal
from your thermostat. Then use that value (only on when both
are satisfied) as the inputs to fans, pumps, equipment etc.

Hello everyone,
I hope you are all doing well and
healthy.
I am modeling a PV powered air
conditioner unit with back up system. My model cuurently
operates. However, I am also planing to switch off the
air conditioner between 18:00 to 08:00 on weekdays and
also at the weekends.
I tried to use type 14 (weekdays and
weekend defination) with type 41 (whole week). But I
could not find the connection for output of type 41,
namely forcing function output for current day. I
suppose that they have to be connected to fan control
signal, mass flow rate or conditioning signals. But they
are all connected to other models like building and
termostat.
Can you please help me on this issue?
Best regards.
