HP - Heating/cooling operation
Testing procedure
Pre-conditions check
Before testing is started, it must be verified that the FCU is running. Verify that device isOccupied.
Setup testing conditions
In order to ensure that testing is accurate, outside sources of heating and cooling need to be eliminated or minimized. If any of these conditions are applicable and not verified, then the testing will be aborted. Stop Active Heating- Verify that discharge temperature is within
10△°F[Heating - Delta] above mixed temperature
- Verify that discharge temperature is within
5△°F[Cooling - Delta] below mixed temperature
Test the Fan
It must also be verified that the fan can successfully be commanded to start and stop. If either of these conditions are not verified, then the testing will be aborted. Test 1: Stop the Fan Weight: 1/10- Command the fan to
OFF - Pass if Fan Speed is reports to be less than
5%[Fan Max Threshold]
- Command the fan to
ON - Pass: Fan Percentage >=
10%[Fan Min Threshold]
Test Heating
Test 3: Start Heating Operation Weight: 4/10- Command Heating to
ON - Pass if zone temp raised by at least
10△°F[Heating - Delta] OR - Pass if discharge temp is greater than
28°F[DAT Heating Arb Threshold]
Test Cooling
Test 4: Start Cooling Operation Weight: 4/10- Command Cooling to
ON - Pass if zone temp dropped by at least
5△°F[Cooling - Delta] OR - Pass if discharge temp is less than
18°F[DAT Cooling Arb Threshold]
