If it is for dual setpoint type 4 thermostat schedule, the heating and cooling temperature should not be the same. There should be a dead band in between although the band can be very small, say, 0.1°C.
You have every thing in the plant (water heater, chiller etc.), air loop and the zone system, but there is no information on how they are used in the zone.
Is UTA a diagram of your system? The IDF itself would be more useful for debugging.

thank,
but it is just my abbreviation for this message...into file is correct.
