pump. Outdoor temperature sensor must be attached. Selection
allows lockout of any W (Electric Heat) when outdoor temperature
is above a selected value. Temperatures of 15 to 55°F (or
equivalent values in °C) can be selected. Feature can be enabled or

feature off.

4. During the selection process, the CLEAN FILTER icon will

remain on, even if OF (off) is chosen.

’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 4
equipment cycles per hour, regardless of setting. Values can range
from 1 to 9. Default 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 deter-
mined 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 4 cycles per hour.
TO ADJUST:

1. Enter configuration mode.

2. Press MODE button to display value between 1 and 9. Factory

default is 3.

3. Use up and down buttons to move between values.

Step 5—Hold, Fan, Mode Button Operation

1. Pressing HOLD button disables the time/temperature schedule

and

holds

the current desired temperature. When active, the

HOLD annunciator is turned on. A second press of the HOLD
button releases the hold feature and turns off the annunciator.

2. Pressing the FAN button alternately selects AUTO or ON fan

operation. Fan annunciator displays the current selection.

3. Pressing the MODE button will select OFF, HEAT, COOL,
