INSTALLATION

Battery Location

WARNING

2 "AA" alkaline batteries are included in the thermostat at

the factory with a battery tag to prevent power drainage.

Remove the battery tag to engage the batteries.

To replace batteries, set system to OFF, remove thermostat

from wall and install the batteries in the rear along the top of

the thermostat (see Figure 1). For best results, use a

premium brand "AA" alkaline battery such as Duracell^®or

Energizer^®.

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.

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 snug-

ly, use plastic screw anchors to secure the base.

4. Fasten base snugly to wall using mounting holes shown

in Figure 1 and two mounting screws. Leveling is for

appearance only and will not affect thermostat operation.

5. Connect wires to terminal block on base using

appropriate wiring schematic (see diagram sheet

37-6808).

6. Push excess wire into wall and plug hole with a fire re-

sistant 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.

WIRINGCONNECTIONS

Refer to equipment manufacturers' instructions for specific

system wiring information. After wiring, see CONFIGURA-

TION section for proper thermostat configuration.

touch keys to select the feature, OFF.

17 & 18) Select Automatic Schedule – This feature allows

programming a “Comfort Temperature” into all program

periods with the Auto Schedule key. When Heat AS (for

Heat mode) or Cool AS (for Cool mode) is selected On,

the Auto Schedule feature is ready to be set. Off

indicates that the feature is not ready to be used or a

“Comfort Temperature is already set. See Auto Schedule

in Programming section.

When the control is in heat pump configuration (HP1/

HP2), the system switch configuration will have an

additional mode available namely, Emer for Emergency

Mode.

6) Energy Management Recovery (EMR) – (this step is

skipped if configured as non-programmable).

When set to "On" causes the thermostat to start heating

or cooling early to make the building temperature reach

the program setpoint at the time you specify.

19) Select Cool Savings™: With Cool Savings™ enabled,

the thermostat will make small adjustments to the

setpoint temperature during periods of high demand to

reduce AC system running time and save energy. When

the cooling system has been running for more than 20

minutes, humidity in the home will be lower and a higher

temperature will feel comfortable. After 20 minutes of run

time, the thermostat will start increasing the setpoint

temperature in steps of less than one degree as the

system continues to run. These adjustments will eventu-

ally cause the system to satisfy the thermostat to turn the

system off and reduce the energy consumption. When

the Cool Savings™ feature is active and making adjust-

ments, the display will flash “Cool Savings”. The amount

of the adjustments to the setpoint temperature is depen-

dent on the Cool Savings™ value that is set, 1 being the

least adjustment and 6 being the most adjustment. With

this feature set to OFF, no change will occur when the AC

system is continuously running during the periods of high

demand. Periods of high demand will normally occur

during the late afternoon and early evening on the hottest

days of the summer. As demand lessens the adjustments

to setpoint temperature are reversed until setpoint

temperature returns to normal and “Cool Savings” no

longer flashes.

Example: Let us say, the heating program is 65°F at

night and 70° at 7 AM. If the building temperature is 65°F,

the difference is 5°F. Allowing 5 minutes per °F rise, the

thermostat setpoint will change to 70° at 6:35 AM.

Cooling allows more time per °F, because it takes

longer to reach temperature.

7, 8 & 9) Cycle Rate Selection – The factory default setting

is fast cycle (FA Cr) in all modes (Heat, Cool, Emer). To

slow cycling (SL, Cr), press touch keys

toggle

between FA & SL. The cycle rates are as below different

10) Select Compressor Lockout (CL) – Selecting 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 of the newer

compressors have already got a time delay built in and

do not require this feature to be activated in the thermo-

stat. Your compressor manufacturer can tell you if

this lockout feature is already present in their system.

When the thermostat compressor time delay is activated,

it will flash the set point for up to five minutes.

Planning Your Program – Important

The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.

The 1F95-1277 comes configured for 7 day programming and can also be configured for 5+1+1 programming (see configura-

tion section).

Factory settings are listed on Monday, Saturday and Sunday. If you are re-programming a 5+1+1 day schedule, pencil in your

own times and temperatures directly below the factory times and temperatures.

If you are re-programming a 7 day fill in all lines with the times and temperatures you want.

Keep the following guidelines in mind when planning your program.

• In Heating, lower temperatures will save energy.

• In Cooling, higher temperatures will save energy.

• If you plan on using Auto Changeover, do not program the heating higher than the cooling.

Wired Remote Temperature Sensing

One remote temperature sensor can be installed indoor or

outdoor and connected to the thermostat by a maximum

cable length of 100 meters (300 feet). Terminals +, S and -

on the terminal block allow connection of the remote sensor.

The thermostat must have 24 VAC Common connection to

terminal C for the remote sensor to operate. The remote

sensor can be enabled or disabled in the Installer/Configura-

tion menu, item 25.

Example: Local sensor temperature is 80° and the remote

sensor is 70°.

If weight is selected H4, the averaged temperature of 72° will

be displayed.

(1 x 80) + (4 x 70) / 5 = 72°

If weight is selected A2, the average temperature of 73° will

be displayed.

(1 x 80) + (2 x 70) / 3 = 73.3°

When remote sensor, Remote, is selected Off (factory

default), no remote sensor is enabled. When remote sensor

is selected On, the next step is to select the remote as

indoor, Remote In, or outdoor, Remote Outdoor. If the

remote is selected as Remote In, an additional step will be to

select if the temperature shown on the display will be from

the thermostat, LS On, or the remote sensor Ls Off.

If weight is selected L1, the average temperature of 75° will

be displayed.

(1 x 80) + (1 x 70) / 2 = 75°

The example shows that the weight selected would prioritize

the overall averaged temperature between the two sensors.

The high weight selection caused the remote sensor to have

a higher influence in the calculated temperature average

than the local sensor and the low weight selection caused

the remote sensor to have less influence.

In normal operation, when a remote sensor is enabled the

time digits of the display will alternate between the time and

the remote temperature for three seconds each. Above the

remote temperature will be Remote, for indoor sensor or

Outdoor Remote, for outdoor sensor. If the remote sensor is

an indoor sensor and the local display has been disabled,

the temperature displayed as the room temperature will be

the remote sensor temperature.

Dual Fuel Temperature Setpoint

When the thermostat is configured for Heat Pump mode and

an outside remote sensor is installed, the thermostat can

monitor the outside temperature. When the outside tempera-

ture falls below a user selectable temperature, the thermostat

will switch to gas heat and shut down the compressor. This

eliminates the need for a fossil fuel kit.

Sensing Range:

Outdoor temperature range is -40 to 140^oF

Indoor temperature range is 32 ^oF to 99^oF

The user selectable temperature is called the dual fuel

temperature setpoint, dF and is set in the Installer/Configura-

tion menu, item 26. The dual fuel temperature setpoint can

be set to a temperature of 5 through 50. A selection of 5

(default setting) disables this feature and menu selection of

Cd will not be available.

Weight of Remote Reading:

The thermostat is designed to receive the temperature of the

indoor remote sensor and average, or weight, it with the local

sensor in the thermostat for each program period. The

averaging will be active only when the local sensor and the

indoor remote sensor are both functional and enabled in the

Installer/Configuration menu.

After the dual fuel temperature setpoint is set above 5 and

is pressed, a delay, Cd, can be set for compressor shutdown

after the auxiliary stage is energized. This delay can be set

from 0 seconds to 99 seconds to minimize the time that the

system may blow cooler air until the alternate source of heat

comes on. Default setting for delay is 60. When setting the

When the thermostat is in the Set Schedule mode, the weight

of the indoor sensor will be shown in the current temperature

digits of the display. The weight will show as A2 (average

and default), H4 (high) or L1 (low). Pressing the

and

delay if the

keys are held depressed, the setpoint

keys at the same time will change the weight for the program

period. The weight of the local sensor is fixed.

will increase or decrease at the rate of one degree every half

second for the first three seconds and double the speed after

three seconds.

In normal operation of the thermostat, the current tempera-

ture displayed will be the weighted average of the local

sensor and the remote sensor using the formula (local

sensor weight x local sensor temperature) + (remote sensor

weight x remote sensor temperature) / (local sensor weight +

remote sensor weight).

TROUBLESHOOTING

Reset Operation

Note: When thermostat is reset, installer configuration menu settings and programming will reset to factory settings.

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by removing

the wires from terminals R and C (do not short them together) and removing batteries for 2 minutes. After resetting the thermostat, replace

the wires and batteries. If the thermostat has been reset and still does not function correctly contact your heating/cooling service person or

place of purchase.

Note: Be sure to review the installer configuration menu settings.

To reset the programming, clock and configuration settings, press

should go blank and then all segments will be displayed momentarily.

Possible Cause

Corrective Action

Symptom

1. Blown fuse or tripped circuit breaker.

2. Furnace power switch to OFF.

Replace fuse or reset breaker.

Turn switch to ON.

No Heat/No Cool/No Fan

(common problems)

3. Furnace blower compartment door or

panel loose or not properly installed.

Replace door panel in proper position to engage safety

interlock or door switch.

4. Loose connection to thermostat or system. Tighten connections.

1. Pilot light not lit.

Re-light pilot.

No Heat

2. Furnace Lock-Out Condition. Heat

may also be intermittent.

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.

3. Heating system requires service or

thermostat requires replacement.

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.

1. Cooling system requires service or

thermostat requires replacement.

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.

No Cool

1. Possible short in wiring.

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.

be influencing the cycle rate.

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 7 (heat) or 8 (cool). If an acceptable cycle rate

is not achieved, contact a local HVAC service person for

additional suggestions.
