When this identifier disappears, normal operation begins. The MODE control should be set to OFF and FAN control to AUTO, so equipment does not start until further configuration and check- out is completed.

Step 4ÐSet Thermidistat Control Configuration

Configuration options, like DIP switch settings, are intended to be selected at installation and normally are not modified by the homeowner. These options are not discussed in the homeowner's manual and therefore must be made as part of the installation. A special procedure allows entry into the configuration mode. While in configuration mode, up to 17 selections can be made. A description of each selection and how to use the configuration mode follows.

TO ENTER CONFIGURATION MODE:

Press and hold FAN button for approximately 10 sec until COOL set point display indicates a flashing 1. The Thermidistat Control is now in configuration mode. It will automatically exit this mode if no button is pressed for 3 minutes. Pressing END button will exit configuration mode immediately.

WHILE IN CONFIGURATION MODE:

The upper small (COOL set point) display indicates selected option number and large display indicates selection made within that option. One of these will be flashing. The up and down buttons are used both to move between available options and to make selection for each option. When option number (small display) is flashing, up and down buttons adjust it, moving between available option numbers. After desired option number has been selected,

press SET TIME/TEMP button once. The large display will now flash, indicating that up and down buttons now control available choices within that option. Each press of TIME/TEMP button switches between available option (small display) and available selections within each option (large display).

CONFIGURATION OPTIONS Ð SELECTION:

Option 1ÐAnticipator Adjustment

This adjustment controls sensitivity and cycle rate of Thermidistat Control. Higher numbers decrease sensitivity and slow cycle rate. Lower numbers increase sensitivity and cycle rate. However, a limiting feature will not allow more than 4 cycles per hr, regardless of setting. Anticipator values can range from 1 to 9. Factory default is 3. This default selection provides optimum performance in nearly all installations. Try it first. Do not change setting unless there is evidence of need to do so.

Unlike conventional anticipators, this setting is not determined by current draw. There is no need to measure, know, or compensate for current draw. There is also no droop with this Thermidistat Control. Regardless of setting and number of stages, both heating and cooling will control to their respective set points.

TO ADJUST:

1.Enter configuration mode if not already there. See Step 4 "To Enter Configuration Mode." The upper small (COOL set point) display will be flashing 1. If not, use up and down buttons to move it to 1.

2.Press SET TIME/TEMP button once to flash current selection of 1, 2, 3, 4, 5, 6, 7, 8, or 9 on large display. Factory default is 3.

3.Use up and down buttons to move between available choices.

4.Press SET TIME/TEMP button again to flash upper small display for selection of another option, or press END to exit configuration mode.

Option 2ÐClean Filter Timer

Select hours of blower operation (heating, cooling, or fan) before CLEAN FILTER icon is displayed. With OFF selected, icon will never come on, disabling this feature. Time selection can range from 400 to 3600 hr by selecting numbers 1 through 9. (Time is 400 X number selected.) Factory default is 2 (800 hr). Recom- mended selections are: disposable filterÐ400 to 800 hr, media filterÐ1200 to 1600 hr, or electronic air cleanerÐ1600 to 2400 hr of blower operation.

TO SELECT OR ADJUST:

1.Enter configuration mode if not already there. See Step 4 "To Enter Configuration Mode." Use up and down buttons to make small (now flashing) display indicate 2.

2.Press SET TIME/TEMP button once to flash current selection of OF, 1, 2, 3, 4, 5, 6, 7, 8, or 9 on large display. Factory default is 2.

3.Use up and down buttons to move between available choices.
