I am cooling type 56 building with type type 752 (Simple Cooling Coil Using Bypass Fraction Approach; Temperature Controlled) by introducing the cool air via ventilation to type 56.
I am controlling the room air temperature by type 2: aquastatC controller. When i run the simulation with 5 min time step, the controller cannot control the room air temperature within the dead band but when i run the simulation with 1 min time step it can control the room temperature within the dead band.
What may be the possible reason.
Looking forward to your answer.
Sincerely
Ashmin Aryal
