To enter the configuration mode:
To enter Configuration Mode, hold the FAN button down for
approximately 15 seconds. After the 15 second period, Option
“01” will appear in the display and the SERVICE icon will be
turned on.
NOTE: If the FAN button is pressed again or if no button is
pressed for 3 minutes, the thermostat will exit the configuration
mode and return to normal operation. To reenter the configuration
mode, the FAN button must be pressed and held for 15 seconds
again.
While in configuration mode:
The display is used to show both the option number and the
selection choice within that option.
OPTION 01 -- ANTICIPATOR ADJUSTMENT
This adjustment controls the sensitivity and cycle rate of the
thermostat. Higher numbers decrease the sensitivity and slow the
cycle rate. Lower numbers increase sensitivity and increase cycle
rate. However, a limiting feature will not allow more than 6
equipment cycles per hour, regardless of setting. Values can range
from 1 to 9. Factory default setting is 3. This default selection will
provide 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 to be
determined by current draw. There is no need to measure, know, or
compensate for current. There is also no droop with this
thermostat, regardless of anticipator setting. This adjustment
controls only sensitivity and cycle rate up to the maximum of 6
cycles per hour.
To Adjust:
1. Enter configuration mode (if not already there).
2. Use up and down buttons to display Option 01. The SET
icon should be off.
3. Press MODE button once. The SET icon will come on. The
display now shows Option 01 setting.

Option 01 values of 1 to 9. Factory default is 3.

hours by selecting numbers 1 through 9. (Time is 400 X number
selected.) Factory default is 2 (800 hours). Recommended
selections are: disposable filter 800 hr, media filter 1200 to 1600
hr, or electronic air cleaner 1600 to 2400 hr of blower operation.

OFF when any W (furnace or strip heat) output is ON. Most
furnaces and fan coils manage their own blowers and do not
require a separate G signal. For these applications, select OFF.
Some auxiliary heaters require a separate G signal to turn on the
blower. In this case, select On. Factory default is OF (off).

the compressor timeguard. (See Operational Information for
details.) These timers MUST be enabled (zoning OFF) for normal
operation and disabled (zoning ON) for zoning applications.
In zoning applications, the zone control center performs these
timing functions. Factory default is OF.
To Select:
1. Enter configuration mode (if not already there).
