WARNING

Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

Remove Old Thermostat

A standard heat/cool thermostat consists of three basic parts:

1) The cover, which may be either a snap-on or hinge type.

2) The base, which is removed by loosening all captive screws.

3) The switching subbase, which is removed by unscrewing

the mounting screws that hold it on the wall or adapter plate. Before removing wires from old thermostat, label each wire with the terminal designation from

which it was attached. Disconnect the wires from the old thermostat one at a time. Do not let wires fall back

into the wall.

Installing New Thermostat

1) Pull the thermostat body off the thermostat base. Forcing

or prying on the thermostat will cause damage to the unit.

2) Place base over hole in wall and mark mounting hole

locations on wall using base as a template.

3) Move base out of the way. Drill mounting holes. If you

are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snugly,

use plastic screw anchors to secure the base.

4) Fasten base snugly to wall using mounting holes shown

in Figure 2 and two mounting screws. Leveling is for appearance only and will not affect thermostat operation.

5) Connect wires to terminal block on base.

6) Push excess wire into wall and plug hole with a ﬁre resistant material (such as ﬁberglass insulation) to prevent

drafts from affecting thermostat operation.

7) Carefully line the thermostat up with the base and snap

into place.

4) GAS or Electric (ELE) fan operation. If the heating system requires the thermostat to energize the fan, select ELE. Select GAS if the heating system energizes the fan on a call for heat.

5) Select Cool Savings™ value – Selects the amount of adjustment for the Cool Savings™ feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. Default value is 0 which disables this feature. Cool Savings is an optional energy saving feature that can reduce your cooling costs. It is based on the principal that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when a cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower the indoor humidity. Cool Savings, very slowly, adjusts the setpoint temperature to make the setpoint closer to the displayed room temperature, to a maximum of the number of degrees you select. Adjusting the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will actually be higher than the thermostat displays but the reduction in humidity will allow comfort at the slightly higher temperature.

To turn this feature on in the Cool mode press Cool

Savings. The display will show “Save” next to the setpoint temperature. When Cool Savings is making adjustments to the room temperature display “Save” will be ﬂashing and the displayed room temperature may vary within the adjustment range you selected.

If “Save” is not displayed and this feature is OFF, no

change will occur when the cooling system is continuously running during periods of high demand.

6) Energy Management Recovery: (this step is skipped if

conﬁgured to be non-programmable). Energy Manage-

or keys are

ment Recovery (E) On enables the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.

Example: E On is selected and your heating is pro-

grammed to 65° at night and 70° at 7 AM. If the building temperature is 65°, the difference between 65° and 70° is 5°. Allowing 5 minutes per degree, the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree, because it takes longer to reach set temperature.

7, 8, 9 & 10) Cycle Rate Selection – The factory default set-

ting for Heat and Cool modes, SS1 and MS2 is medium cycle (ME). For Heat Pump and HP1, the default setting is medium (ME). For Emer (Aux) the default setting is fast cycle (FA). To change cycle rate, press the

key. Cycle rate differentials for different settings are: Fast Medium Slow

MODE FA ME SL Heat (SS1, MS2) 0.4°F 0.6°F 1.7°F Cool (SS1, MS2) 0.9°F 1.2°F 1.7°F Heat Pump (HP1) 0.9°F 1.2°F 1.7°F Emer (HP1) 0.6°F - 1.7°F

11) Select Compressor Lockout CL OFF or ON – Select-

ing CL ON will cause the thermostat to wait 5 minutes

between cooling cycles. This is intended to help protect

the compressor from short cycling. Some newer com-

pressors already have a time delay built in and do not

require this feature. Your compressor manufacturer can

tell you if the lockout feature is already present in their

system. When the thermostat compressor time delay oc-

curs, it will ﬂash the setpoint for up to ﬁve minutes.

12) System Mode Conﬁguration – This thermostat is con-

ﬁgured for Heat and Cool with Auto Changeover (SYS-

TEM switch with Heat, Auto, Cool, Off). It can also be

conﬁgured for Heat and Cool (Heat, Cool, Off), Heat only with Fan (Heat, Off, FAN Switch) Heat only without Fan

(Heat, Off) Auto only (Auto, Off) and Cool only (Cool,

Off).

13) Select Backlight Display – The display backlight im-

proves display contrast in low lighting conditions. When

the “C” terminal is powered, selecting backlight CdL ON

will keep the light on continuously. Select backlight OFF

will turn the light on momentarily after any key is pressed.

When the “C” terminal is not powered, the light will be on

momentarily after any key is pressed no matter whether

the backlight is selected ON or OFF.

14) Select Temperature Display Adjustment 4 LO to 4 HI

– Allows you to adjust the room temperature display up

to 4° higher or lower. Your thermostat was accurately cali-

brated at the factory, but you have the option to change

the display temperature to match your previous thermo-

stat. The current or adjusted room temperature will be

displayed.

15) Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.

19 & 20) Select Automatic Schedule – 1F85 only, with just

one touch of the Auto Schedule key this feature allows you to program a desired comfort temperature into all the program periods along with a 6° set back for night peri-

ods of both Heat and Cool programs. Factory default is

“On” for both. When Heat AS On and Cool AS On are

activated while in Heat or Cool mode, select desired

setpoint temperature and press Auto Schedule. This

value will be copied into all the morning, day and evening

program periods. The night program periods will have a

6°F set back. 21 & 22) Select Fast Second Stage ON or OFF – Heat

pump or Multi-stage only, in the run mode, with the fast

Heat feature enabled (FA Heat On), if the Heat setpoint

temperature is manually raised by 3°F (2°C) or more

above the actual temperature using

stage will energize immediately. With FA OFF, second

stage will not energize until the setpoint temperature is

1°F or more above actual temperature for more than ten

minutes. The Fast Cool feature (FA Cool) provides the

same controls when the setpoint temperature is lowered.

23) Comfort Alert with Active Protection – Turn this

feature ON to enable active protection. This allows the

thermostat to identify fault codes sent by the Comfort

Alert module when compressor damage is possible and

react to those codes by turning the compressor off. Fault

codes from the Comfort Alert module will ﬂash on the

thermostat. (Refer to Comfort Alert Yellow Alert Codes

or keys. A selection of 0 Days for

in Troubleshooting section.) If a Comfort Alert module is not connected, or to disable active protection, turn this feature OFF. If a Comfort Alert module is connected and this feature is turned OFF, the thermostat will still receive and ﬂash the fault codes from the Comfort Alert module, but the active protection will not be enabled to protect the compressor.

24) Select Daylight Saving Time Calculation – 1F85 only, this feature will allow the thermostat to calculate the DST automatically and apply it to the Real Time Clock display. Default On. Use feature OFF.

25 & 26) Select Filter Replacement Reminder and Set

Run Time – Select the “Change Filter” reminder On or OFF. If selected On, press MENU to select the time period from 25 to 1975 hours in 25 hours increments. In a typical system, 200 hours (default) of run time is approximately 30 days. After the selected time of blower operation, the thermostat will display “Change Filter” as a reminder to change or clean your air ﬁlter. When “Change Filter” is displayed, press MENU or RUN SCHED button to clear the display and restart the time to the next ﬁlter change.

27) Select Reversing Valve Output – The O/B option is factory set at “O” position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the

thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B option should be set at “B” position.

OPERATING YOUR THERMOSTAT IMPORTANT!

Second Stage Time Delay

Your thermostat is designed to determine the optimum time to activate the second stage. Simply raising the temperature in heating or lowering it in cooling will not always force the thermostat to bring the second stage on quickly. There is a time delay from 0-30 minutes depending on the performance of the ﬁrst stage of the system.

EXAMPLE: For the last 2 hours the thermostat is set on 70° and the room temperature is 70° with the equipment using only the ﬁrst stage of heat. Since the equipment is keeping the temperature within 1° of setpoint, the thermostat will

delay second stage for a longer time if you manually raise the temperature or if the room temperature quickly changes. Once the second stage comes on, it will come on sooner the next time there is a difference between the setpoint and the room temperature. The net effect of the staging program is that when the ﬁrst stage is capable of making temperature the second stage will delay longer. When the thermostat calculates that ﬁrst stage cannot make temperature in a reasonable time, the second stage will come on sooner. This built in function automatically optimizes the use of additional stages of heat or cool.

Comfort Alert Codes

The Comfort Alert diagnostics product monitors the air conditioning outdoor systems with single phase Copeland Scroll compressors. Abnormal system and electrical conditions are indicated by ﬂashing ALERT codes on the yellow LED on the Comfort Alert module. The ﬂash codes are transmitted to the thermostat by the Comfort Alert Thermostat interface module. The Comfort Alert compatible thermostat displays “Call For Service” that ﬂashes at the same rate as the yellow LED on the Comfort Alert module.

Replace fuse or reset breaker. Turn switch to ON. Replace door panel in proper position to engage safety interlock or door switch. Tighten connections.

Re-light pilot. Many furnaces have safety devices that shut down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local HVAC service person for assistance. Diagnostic: Set SYSTEM Switch to HEAT and raise the setpoint above room temperature. Within a few seconds the thermostat should make a soft click sound. This sound usually indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed above. If the thermostat does not click after being reset contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a HVAC service person to verify the heating is operating correctly.

Same as diagnostic for No Heat condition except set the thermostat to COOL and lower the setpoint below the room temperature. There may be up to a ﬁve minute delay before the thermostat clicks in Cooling.

Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal block. Try resetting the thermostat as described above. If the condition persists the manufacturer of your system or service person can instruct you on how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat.

The thermometer can be adjusted +/- 4 degrees. See Temperature Display Adjustment in the Conﬁguration Menu section.

Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently but runs for a shorter time so there is no increase in energy use. If you would like an increased cycle time, choose SL for slow cycle in the Conﬁguration menu, step 6 (heat), 7 (cool) or 8 (heat pump). If an acceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions.

Hold MENU key for 20 seconds and the lockout will reset.
