    Heat pumps?
    We usually run 75-80 in the summer and 70-75 in winter. Depends on the units and boiler/tower.

    The air handlers have a hot water coil for heating, and a separate chilled water coil for cooling. The chilled water loop temps should be ?

    44 degrees is pretty close to the normal chilled water fan coil setpoint for Leaving water temp. Doesn't really matter water entering temp is as long as is not more than 10 degs more than setpoint and your chiller can load up and down to match the load.

    I agree. Most chilled water setpoints run from 42 to 50 depending on load and humidity levels.

    Leaving water temp out of the chiller barrel or the leaving water temp after its went through the coil? I think you meant the water temp entering the coil?
