Numbers or text fields. If the setting is a number or text field, use the arrow keys to select the value for the first character, and press the ENTER key to move to the next character position. Repeat this procedure to select and set each character. After the last character is set, press the ENTER key to save the setting and exit from input mode. Press the ESC key to exit without saving.

Stop the System

Path: Main Menu > On/Off

To stop the System, select the On/Off option on the main menu and change the setting to Off.

Note: Change the setting to Off to shut down all modes of operation and the blower fan; the display interface and the controller will continue to receive power.

For Systems with electric reheat, the blower fans may continue to operate for up to 60 seconds to purge heat from the System.

Factory default settings

All Module settings are controlled through the display interface on the front of the Main Module for each System. The factory default temperature is set at 22.2°C (72°F ) in the cooling mode, and 20°C (68°F ) in the reheat mode. The default deadband is set at 1.1°C (2°F).

Similar to DX cooling, the output for dehumidification is determined by the difference between the setpoint and the average return humidity from each of the Modules in the System if more than one Module is present. The deadband is used to engage both compressors incrementally with increasing demand. Each Module in the System is assigned an equal division of the deadband a percentage of relative humidity. Both compressors in a Module are engaged when the assigned division of the deadband above the setpoint is reached. If the average return humidity reaches the setpoint plus the entire deadband, all of the compressors will be engaged until the humidity drops below the setpoint plus the deadband. Unlike DX cooling, the compressors in each Module are normally set to work as a single unit instead of separately. The use of one or two compressors per Module is based on the Dehum.
