I am modeling a DOAS with chill water coil for dehumidification. I want to keep the zone RH under 55% and limit the DOAS output humidity ratio. I have

1. Set a humidification/dehumidification schedule on the Thermal Zones. Both schedules of type "Percent". Humidification schedule is set to 0 for no humidification, and dehumidification is set to 55.
2. Set SetpointManager:MultiZone:Humidity:Minimum and SetpointManager:MultiZone:Humidity:Maximum at cooling coil outlet node.
3. Set Controller:WaterCoil sensor node = cooling coil outlet node
4. Set Controller:WaterCoil actuator node = chill water inlet node

But the cooling coil never runs, and there is no dehumidification. Can anyone take a look a my model and tell me what did I do wrong. https://360cloud.egnyte.com/navigate/folder/ac2b3ca0-0d0b-4778-9db4-86ba7da422d1

Thanks!
