I have an AHU which is turned off during night and weekends. I want to add a control to turn it on if the temperature in my zone drops below 14°C.
Until now I was using the Availability Schedules of my objetcs (coils, air terminal, outdoor air controller...) to stop them. Then I found the HVAC Operation Schedule and Night Cycle option. Is this the right way to use it ? :
- Set the Availability Schedules of all HVAC objects to always on.
- Set the HVAC Operation Schedule to turn off HVAC during nights and weekends.
- Set a thermostat to the setpoint (14°C for me) during nights and weekends.
- Use Night Cycle: Cycle on Full System if Heating or Cooling Required.
If this is correct, I have a question: Is it possible to control the behavior of the system during Night Cycle ? If my temperature drops below 14°C I want to heat until it reaches 16°C and then turn it off again.
