INTRODUCTION
Can-ier residential thermostats are waft-mounted, low-voltage
thermostats which maintain room temperatnse by controlling the
operation of an HVAC (heating, ventilation and air conditioning)
system. Separate heating and cooling set points and auto-
changeover capability provides maximum comfort and flexibility.
Some applications may require the addition of a jumper from RC
to RH (see wiring diagrams). The thermostat comes factory
configured for air conditioner operation. See Fig. 1 for thermostat
dimensions. During power interruption the internal memory stores
settings indefinitely. Batteries are not required. The thermostat
requires 24 vac (both R and C terminals) to be connected for
proper operation. The thermostat will not operate without the
required connections. (See Table 1).This AC Model (1-stage cool
1-stage heat) thermostat is to be used for single-stage heating
and/or cooling applications only. This thermostat has separate heat
and cool circuits. Some applications require the addition of a
jumper from RC to RH. See applicable wiring diagram for more
information, This thermostat can be used with optional outdoor
temperature' sensor.

difioner
Step 3--Set Thermostat Configuration
Configuration options are intended to be selected at installation
and are not normaily modified by the user. These options are not
available in the owner's manual and must be done as part of the
installation.
To enter Confi_wation mode, press and hold the FAN button for
approximately 10 sec until the room temperature disappears and
display reads "01". The thermostat is now in Configuration mode.
If a button is not pressed for 3 minutes, the thermostat will
automatically exit this mode.
The display is used to show both the option number and the
selection choice within that option.
CONFIGURATION OPTIONS -- Several different configura-
tions can be set while in Configuration mode.
Anticipator Adjustment
This adjustment eonh'ols sensitivity and cycle rate of thermostat.
Higher numbers decrease sensitivity and slow cycle rate. Lower
numbers increase sensitivity and cycle rate. However, alimiting
feature will not allow more than 4 cycles per hour, regardless of
setting. Anticipator values can range from 01 to 09. Factory default
is 03, This default setting will provide optimum performance in
nearly all installations.
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 thermostat.
Regardless of setting and number of stages, both beating and
cooling will control to their respective set points.
1. Enter Configuration mode ff not already there. See above. The
upper small display will indicate 01. IfOl is not displayed, use
UP and DOWN arrows to move to 01.
2. Press MODE button once to display the Set icon.
3. Use UP or DOWN arrows to move between available choices
of 01 through 09, Factory default is 03.
4. Press MODE button again and Set will appear. Use the UP or
DOWN arrows to select another option or press FAN to exit
Configuration mode.
Clean Filter Timer
Select hours of blower operation (heating, cooling, or fan) before
CLEAN FILTER icon is displayed. With OF (off) selected, icon
will never come on, disabling this feature. Time selection can
range from 400 to 3600 hr by selecting numbers ill through 09.
(Time is 400 Xnumber selected.) Factory default is 02 (800 hr).
Recommended selections are: disposable filter -- 400 to 800 hr,
media filter -- 1200 to 1600 hr, or electronic air cleaner -- 1600

owners may want to have displayed temperature adjusted to a
higher or lower value. The selected number is number of degrees,
plus or minus, which will be added to actual temperature. The
numbers can range between -5 and +5. Factory default is 0. This
adjusted value will be used as actual temperature for both display
and control action. For example, if 2 is selected, 72 F actual will
read 74 F. If set point is 72 F, the room will control to an actual
temperature of 70 Fwhich will be displayed and acted upon as if
it were 72 F. This thermostat is factory calibrated within an
accuracy of plus or minus 1° F. This adjustment will provide the
best accuracy when set to 0.

OPERA.ON
Five-Minute Compressor Time Guard -- This timer prevents
the compressor from starting unless it has been off for at least 5
minutes. It can be defeated for one cycle by simultaneously
pressing the FAN mode button and the UP arrow.
Fifteen-Minute Cycle Timer -- This timer prevents the start of a
heating or cooling cycle until at least 15 minutes after the last start
of the same cycle. Its function is to assure that equipment is not
cycled more than 4times per hour. This timer is defeated for one
cycle when the desired temperature is manually changed. It can
also be defeated for one cycle by simultaneously pressing the FAN
mode button and the UP button.
Fifteen-Minute Staging Timer -- In multistage heating or
cooling, this timer prevents any higher stage from turning on until
the preceding stage has been on for 15 minutes. This timer is
defeated if the temperature difference is greater than 5° F (usually
due to a large change in desired temperature).
Three-Minute Minimmla On Time -- In normal operation when
a stage is operating it will stay on for three minutes before turning
off.

SYMPTOM WHAT TO CHECK
Check for 24 vac between R and C at terminal connections.
Blank LCD Both R and C must be connected for proper operation.
Temperature sensor (inside thermostat) reading out of
range. Check sensor for damage. The outdoor temperature
"-" (2 dashes) On Temperature Display sensor (if installed) is open, not connected, or shorted (both
buttons pushed simultaneously). If recycling power does not
clear display, thermostat should be replaced.
Brownout condition or voltage too low to thermostat. Double
"E2" On Temperature Display check winng and check for 24 vac between R and C. E2
will clear 15 sec after proper voltage is restored.
After the selected number of hours of blower operation =FIL-
TER" will display on LCD, This is to remind the homeowner
"RLTER" On Temperature Display to "check" the filter. Press RESET FILTER button to clear
display and reset timer to 0.
Select COOL mode. Set desired temperature to 10° F be-
low room temperature. Simultaneously press FAN and UP
arrow buttons to defeat timers. Check for COOL ON icon
Cooling Will Not Come On and 24 vac at Y (first-stage) terminal. If present, thermostat
is OK and problem is with equipment or widng. If not
present, replace thermostat.
Selact HEAT mode. Set desired temperature to 10° F
above room temperature. Simultaneously press FAN and
Heating Will Not Come On UP arrow buttons to defeat timers. Check for HEAT ON and
24 vac at W. If present, thermostat is OK and problem is
with equipment or widng. If not present, replace thermostat.
Heat/Cool Set Points (Desired Temperatures) -- A minimum
difference of 2_is enforced between heating and cooling set points.
This is done by allowing one setting to "push" the other, to
maintain this difference.
Auto Changeover-- When the auto changeover mode is selected,
a change from heat to cool (or vice versa) will not occur until an
opposite mode demand has existed for 20 minutes. If the set point
is changed, the 20 minute requirement is ignored.
Power On Check-- When AC power is first applied, all segments
of the display are turned on for a few seconds, and the temperatme
display indicates the 2<ligit code: "AC" for single-speed air
conditioner.
Outdoor Temperature --When artoutdoor temperature sensor is
attached, outdoor temperature can be read by pressing UP and
DOWN arrows at the same time.
