When the unit is in either the Off or Run mode, the 7-Day Programming mode can be entered by pressing the “PROG” and “TIME” buttons simultaneously for three seconds. When the “PROG” and “TIME” buttons are pressed simultaneously again or left idle for 20 seconds, the control shall save the new settings and return to the previous interface mode.

While in the 7-Day programming mode, use the up or down arrows to change the time, temperature or period settings. Use the “MODE” (BACK) or “PROG” (NEXT) buttons to select the mode to be changed.

Settings for (1) Day of week, (2) Pe- riod of day, (3) Hour, (4), Minute, (5) Cool setpoint temperature, (6) Heat setpoint temperature and (7) Auto setpoint tem- perature can be entered.

Quick Copy

Quick copy is a feature of the 7-day programming mode. It is used to copy the settings of any day to the rest of the week. While in 7-day programming, select the day to be copied. Then, press the “FAN” and “PROG” buttons simultaneously for three seconds. The selected day will be copied to the rest of the week.

Manual run

This is normal operating (non pre-pro- gram run) mode. Settings for temperature, mode and fan speed are selected by the user and will not change with the passing of time. The word “PROGRAM” does NOT display on the LCD.

Pre-programmed run mode

This feature allows the setpoint tem- perature to be changed according to the pre-programmed set point and time of day settings. The setpoint and time settings are programmed into the control through the 7-day programming interface.

The Pre-programmed Run mode can be entered from Cool, Heat or Auto modes only. Pre-programmed run mode can- not be entered from Dry or Fan modes. Pressing the “PROG” button momentari- ly will enter or exit the Pre-program run mode. The word “PROGRAM” will appear in the LCD display. Then, with the pass- ing of time, the setpoint will change to the programmed setting at the time selected.

Filter Check

To aid in filter maintenance, the micro- processor will keep track of the units run time. Then, after the filter check time has elapsed, a “FILTER CHECK” warning will appear the LCD display. The filter check time is selectable through the configura- tion mode. Available settings are 250, 500, 750, 1000, and 1250 hours. Also if four evaporator freeze ups occur within a 24 hour period, (See fault condition E03) the filter check indicator will appear.

After filter maintenance has been per- formed, press the “MODE” and “FAN” but- tons simultaneously for three seconds to clear the filter check warning.
