Pre-Conditions Check
- Check that device is “Occupied”. If not, STOP the workflow and ARCHIVE.
Test the Fan
Test 1: Stop the Fan Weight: 1/ 5
- Pass if Fan Speed is less than 5% [Fan Max Threshold]
Test 2: Start the Fan
- Pass: Fan Percentage >= 10% [Fan Min Threshold]
If Test 1 or Test 2 Fail, STOP the workflow.
Test Cooling
There are two methods available to verify successful cooling operation. You can use an static setpoint (DAT Cooling Arb Threshold) that the discharge temperature must reach, or you can set a minimum change in temperature (Cooling - Delta) to validate cooling had occurred.
Use the boolean parameter, Arb Setpoint, to choose the method, with the default (False) indicating the use of the delta for verification.
Test 3: Start Cooling Operation Weight: 4/ 5
If Arb Setpoint [False] ,
- Command Zone Temp Setpoint to 5△°F [Delta Setpoint] less than Zone Temp
- Pass if Discharge Air is 5△°F [Cooling - Delta] less than Zone Temp
Otherwise if Arb Setpoint is True ,
- Command Zone Temp Setpoint to 65°F [Arb Cooling Setpoint]
- Pass if Discharge Air is less than 18°F [DAT Cooling Arb Threshold]
