6.1System Testing
6.1.1Environmental Control Functions
The performance of all control circuits can be tested by changing the setpoints, which activates each of the main functions.
6.1.2Cooling
To test the cooling function, set the setpoint to a temperature of 10°F (5°C) below room temperature. A call for cooling should register and prompt the equipment to begin cooling cycle. (Disregard any temperature alarms). Upon completion of testing, return setpoint to the desired temperature.
6.1.3Heating
Reheat may be tested by setting the setpoint 10°F (5°C) above room temperature. A call for heating should register and prompt the equipment to begin heating cycle. (Disregard any temperature alarms). Upon completion of testing, return setpoint to the desired temperature.
6.1.4Humidification
To check humidification, set the humidity setpoint at RH 10% above the room humidity reading. After a short delay, the canister will fill with water and steam will be produced. Upon completion of testing, return the humidity setpoint to the desired humidity.
6.1.5Dehumidification
The dehumidification performance can be tested by setting the humidity setpoint at RH 10% below room relative humidity. The compressor should turn on. Upon completion of testing, return humidity setpoint to the desired humidity.
6.1.6Remote Shutdown
A connection point is provided for remote shutdown devices supplied by the customer. This terminal strip is located in the electric panel. (Terminals 37 and 38 are fitted with a jumper when no remote shutdown device is installed).
