Cool Test
1. Using the building automation system (BMS), adjust
room cooling setpoint to 5 degrees below room
temperature.
2. Air conditioning should come on within five (5) minutes.
Status indicator may come on.
3. Using the BMS, adjust the set temperature 2 degrees
above the room temperature and the A/C should turn off.
There may be a fan delay on your system.
Heat Test
1. Using the building automation system (BMS), adjust
room heating setpoint to 5 degrees above room
temperature.
2. Heating should come on within five (5) minutes. Status
indicator may come on.
3. Using the BMS, adjust the set temperature 2 degrees
above the room temperature and the A/C should turn off.
There may be a fan delay on your system.
