Exiting Configuration Mode — 

To exit the configu-

ration mode, press the 

fan

 button.

SYSTEM START-UP AND CHECKOUT

Installer Test Mode — 

This thermostat has a built-in in-

staller test capability. It allows easy operation of equipment

without delays or set point adjustments to force heating or

cooling. To enter installer test mode, press and hold the

 

fan

button for 15 seconds (after 10 seconds installer configuration

is entered; a continuous 15 seconds and installer test is

entered). At the start of installer test, the mode is Off, the fan is

"fan auto" and the set point displays “InS.”

The 

mode

 button is used to change the system operating

mode to test the heating and cooling equipment. Auto mode is

not available during installer test.   

When the mode is set to heat, heating is energized for

180 seconds. During the installer test operation, the "on" icon is

displayed.

At the end of the equipment test cycle the mode returns to

OFF. 

The LCD display counts down the time remaining (in sec-

onds, from 180 to 0) for each stage when the equipment is en-

ergized. See Fig. 5. 

 

The same procedure is repeated for the cool mode. "C" is

displayed when cooling is active.

The test of a heating or cooling cycle can be terminated be-

fore the timer counts down to zero by pressing the 

mode

button.

Pressing the 

fan

 button alternates the fan selection between

fan auto and fan on and the fan output follows accordingly.

There is no timer associated with the installer testing of the fan

operation.

Setting the mode to Em heat, if available, turns on the auxil-

iary heat for 180 seconds. The space temperature location dis-

plays an "E," the clock display counts down from 180 to 0 in

one-second increments and the "aux heat on" icon is displayed.

At the end of the 180 seconds, the mode returns to OFF.

Terminating Installer Test — 

After 15 minutes of no

button presses by the installer, installer test is terminated.

Pressing the up button, down button, or cycling thermostat

power at any time during installer test terminates the installer

test and returns the thermostat to normal operation.

Checklist — 

The following installer checklist should be

performed after completing installation:

1. Run equipment through several heating and cooling cy-

cles to ensure proper operation. To operate the thermostat

in its normal operating mode, consult the Owner's

Manual.

2. If the equipment is to be left in operation, the set points

and operating mode must be properly selected.

3. Put away tools and instruments and clean up debris.
4. Review and leave Owner's Manual with customer.

OPERATION

Mode Selection  — 

The 

mode

 button allows the user to

display the off, heat, cool, auto and emergency heat icons.

Pressing the 

mode

 button cycles through the available modes

based on the equipment selection from Option 01, the auto

availability setting from Option 15, and the electric heat avail-

ability from Option 35. Available choices are listed in Table 2.

Table 2 — Mode Selection

Fan Selection — 

Pressing the

 fan

 button toggles between

the Fan On and Fan Auto selections. When the “fan on” icon is

displayed, the fan operates continuously. When “fan auto” is

displayed, the fan will run only with the equipment.

Set Temperature Selection — 

If auto mode is not ac-

tive and off mode is not active, pressing the 

up 

or

 down

 button

causes the set point corresponding to the current system mode

to be updated. If the 

up 

or

 down

 button is held, the set point

value will be scrolled. The set point change also takes into ac-

count that Option 11 (deadband) is preserved along with ensur-

ing that Option 26 (minimum cooling set point) and Option 27

(maximum heating set point) are taken into account to enforce

set point limits.

If auto mode is active, pressing the 

up 

or

 down

 button

causes the set point corresponding to the current operating

mode to be updated. To move between the heat and cool set

points, press the 

mode

 button to toggle between set points.

Once the desired set point has been adjusted, press the 

mode

button to return to auto mode.

If off mode is active, the 

up 

and

 down

 buttons are ignored

for changing set point(s).

When changing the set points, the following restrictions are

in place. The cool set point cannot be increased above 90 de-

grees F (32 C) or decreased below Option 26, the minimum

cooling set point. The heat set point cannot be decreased below

50 F (10 C) or increased above Option 27, the maximum heat-

ing set point. 

When Option 39 is set to SP (set point), the set point adjust-

ment is displayed in the large space temperature digits.

Batteries — 

Battery operation is available for installations

where there is no common (C) wire available at the thermostat.

For battery operation, install two alkaline AA batteries. The
