Use the Up and Down arrow keys to scroll through the submenu, then press the ENTER button to access a function. To make changes or review the current setting, see 4.3.1 - Viewing or Changing Settings.

NOTE

Setpoints and system setup parameters are kept in non-volatile memory.

RESTART TIME DELAY

This function specifies the time for the unit to restart after main power is restored to the unit. If sev- eral systems are operating, the time delays should be set to different values to cause a sequential start. Delay can be set from 0.1 minutes (6 seconds) to 9.9 minutes. Setting the value to “NO!” will prevent the unit from restarting when power is restored. In this case, the unit must be restarted man- ually by pressing the “On/Off” key.

To make changes or review the current setting, see 4.3.1 - Viewing or Changing Settings.

C/F DEGREES

The control can be selected to show readings and setpoints in either degrees Fahrenheit (F) or Celsius (C). To make changes or review the setting, see 4.3.1 - Viewing or Changing Settings.

PUMP START TD

The user may set a pump start time delay (in seconds) to ensure that refrigerant begins flowing when the pump starts. If refrigerant does not begin flowing before this delay expires, the pump will stop for a period that the user may also specify (see PUMP OFF TD). After this delay, the pump will again begin its startup sequence.

To make changes or review the current setting, see 4.3.1 - Viewing or Changing Settings.
