9.1 System Testing

The performance of all control circuits can be tested by actuating each of the main functions. This is
done by temporarily changing the set points

9.1.1 Cooling

To test the cooling function, set the setpoint for a temperature of 10°F (5°C) below room
temperature. A call for cooling should be seen and the equipment should begin to cool. A high
temperature alarm may come On. Disregard it. Return setpoint to the desired temperature

9.1.2 Heating

Reheat may be tested by setting the setpoint for 10°F (5°C) above room temperature. A call for
heating should be seen and the heating coils should begin to heat. Disregard the temperature alarm
and return the setpoint to the desired temperature.

9.1.3 Humidification

To check humidification, set the humidity setpoint for an RH 10% above the room humidity reading.
For infrared humidifiers, the infrared element should come On. Steam generating humidifiers should
click immediately as it energizes. After a short delay, the canister will fill with water. The water will
heat and steam will be produced. Return the humidity setpoint to the desired humidity.
