[Equest-users] Turn Cooling Off

[MatthewRLarson at Eaton.com]

Josh,

 

Have you tried changing the Loop Operation in the circulation loop
properties under the Operation tab to "Scheduled" and then specifying a
Cooling Schedule (ON/OFF/TEMP) that disables the loop during the summer
months (with a 0)?  For the Fan Coil, make sure your fan schedule uses a

(-1) during the times you want the fan off or if you have the Night
Cycle Control not set to Stay Off, they will cycle on to meet setpoint.

You could also try to make the cooling setpoint ridiculously high during
the summer so there is no need for heat.  Is the whole building shut
down during the summer so there is no conditioning going on at all in
the building?  Hope one of these comments help or if I'm missing the
boat on your intention, feel free to elaborate.

Thanks,

Hello eQuesters,

 

I am struggling to correctly control my chiller in a chilled water loop
fan coil system.  When I look at my SS-E report they are always
indicating cooling (and fans) available all year long.  I have created
Fan and Cooling Schedules of very type (ON/OFF, ON/OFF FLAG, ON/OFF
TEMP) to specify that my facility is NOT operating (off) for June, July,
and August, yet no matter what I've done I am still getting energy
consumption to cool during these times!

 

I've applied my Cooling Availability schedule to the Fan Coils, the
Chiller, the loop Pump and it still seems like something is overriding
the control.

 

Any insight would be very appreciated.

 

Thank you and be well.

Josh
