Hi there,
I'm trying to provide humidity control to the supply air and allow the supply air in cooling to be provided at the lowest possible energy.
To achieve this I have setpointmanager:warmest providing supply air between 13 and 18.5 degrees, and a humidity setpoint controlling the humidity ratio to 0.0072kg/kg. The problem is because the setpoint controller for the warmest has to be placed after the heating coil, the boiler is heating the water up to the maximum available to maintain the zone temperature deadband. I cannot move the setpoint onto the cooling coil air outlet as the setpointmanager:mixedair requires that setpoint and it cannot control both.
Has anyone else had this issue? If so, how did you prevent the heating coil from unneccessarily heating, while allowing the supply temperature to not be set to a constant temperature?
Thanks in advance,
Alex
