Batteries  
WARNING  
!
2 "AA" alkaline batteries are included in the thermostat. To in-  
stall the batteries, pull the battery door as shown by the arrow  
and lift open. Using the polarity indicated inside the battery  
door, insert the batteries. To close the battery door, swing the  
door down while pulling in the direction of arrow. Once fully  
down, snap the door back into position.  
Thermostat installation and all components of the control  
system shall conform to Class II circuits per the NEC  
code.  
Remove Old Thermostat  
To replace the batteries, set system to OFF, following the  
instructions above.  
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.  
Figure 1 – Battery door shown open  
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.

SS/HP Switch  
(Conventional or Heat Pump Selection)  
The SS/HP switch is factory set to the SS position. In this posi-  
tion, thermostat is configured as conventional single stage. If  
you have a single stage heat pump system, switch SS/HP to  
HP position (see figure 2).

Gas/Elec Switch (Fan Option)  
The GAS/ELEC switch is factory set to the GAS position. In  
this position, the thermostat will not power the circulator fan on  
a call for heat, but will power the circulator on a call for cool.  
If your system requires that the thermostat power the circula-  
tor fan on a call for heat, this switch should be set to the ELEC  
position. Typically, gas and oil heating systems do not require  
the thermostat to power the circulator fan during a call for heat.  
If your heat is gas or oil, the switch should be set to the GAS  
position.

"Ahorro" will appear under "Vent"  
1. Select Reversing Valve Output (SS/HP switch must  
be set at HP, omitted if SS/HP switch is SS Position)  
– 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  
FRIO. 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 CALOR, the O/B  
option should be set at "B" position.  
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. Frio Ahorro operates  
during periods of high demand which normally occur  
on the hottest summer days when the cooling system  
may run for hours to reach the thermostat setting. Long  
cooling run times also lower the indoor humidity. Frio  
Ahorro very slowly adjusts the setpoint temperature to  
make the setpoint closer to the displayed temperature, to  
a maximum number of degrees selected. 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. When Frio  
Ahorro is making adjustments, "Save" will show next to  
the setpoint temperature and the room temperature may  
vary within the adjustment range selected.  
2. Program Options 1F80 only – This control can be  
configured for 5/2 day or 5/1/1 day programming or non-  
programming mode. The default setting is P2, indicating  
5/2 day programming. The programs per week can be  
toggled to P3 or P0 by pressing the  
or  
keys. A  
selection of 0 Days for non-programmable will eliminate  
the need for EMR, and that step in the menu will be  
skipped.  
3. Select Frio Ahorro (Cool Savings™) and value  
– Selects the Frio Ahorro feature On or OFF. If selected  
On, press MENU to select the amount of adjustment  
for the feature in Frio mode with 1 (1°) being the least  
amount of adjustment and 6 (6°) being the most amount  
If this feature is selected OFF, no change will occur when  
the cooling system is continually running during periods of  
high demand.

configured to be non-programmable).  
Energy Management 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.  
10.Select Backlight Display – The display backlight  
improves display contrast in low lighting conditions. When  
the "C" terminal is powered, selecting backlight L ON will  
keep the light on continuously. Select backlight OFF will  
keep 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.  
Example: If E On is selected and have your heating  
programmed 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.  
11.SelectTemperature 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  
calibrated 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 on the left side of the display.  
5, 6 & 7. Cycle Rate Selection – The factory default settings  
with SS/HP switch in SS position for Heat is medium

8. Select Compressor Lockout CL OFF or ON – 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 newer  
compressors 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 occurs, it  
will flash the setpoint for up to five minutes.

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 thermo-  
stat 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  
and  
and the VENT button simultaneously. The  
thermostat should go blank and then all segments will be displayed momentarily.  
Symptom  
Possible Cause  
Corrective Action  
No Heat/No Cool/No 1. Blown fuse or tripped circuit breaker.  
Replace fuse or reset breaker.  
Turn switch to ON.  
Replace door panel in proper position to engage safety interlock  
or door switch.  
2. Furnace power switch to OFF.  
Fan (common  
problems)  
3. Furnace blower compartment door or  
panel loose or not properly installed.  
4. Loose connection to thermostat or system.  
Tighten connections.  
No Heat  
1. Pilot light not lit.  
Re-light pilot.  
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 assis-  
tance.  
Diagnostic: Set SISTEMA Switch to Calor and raise the set-  
point above room temperature. Within a few seconds the thermo-  
stat 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.  
3. Heating system requires service or  
thermostat requires replacement.  
No Cool  
1. Cooling system requires service or  
thermostat requires replacement.  
Same as diagnostic for No Heat condition except set the thermo-  
stat to Frio and lower the setpoint below the room temperature.  
There may be up to a five minute delay before the thermostat  
clicks in Cooling.  
Heat, Cool or Fan  
Runs Constantly  
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 ter-  
minal 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.  
2. Possible short in thermostat.  
3. Possible short in heat/cool/fan system.  
4. VENT Switch set to VENT ON.  
Thermostat Setting &  
ThermostatThermometer  
Disagree  
1. Thermostat thermometer setting  
requires adjustment.  
The thermometer can be adjusted +/- 4 degrees. See Tempera-  
ture Display Adjustment in the Configuration Menu section.  
Furnace  
1. The location of the thermostat and/or  
the size of the Heating System may  
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 in-  
creased cycle time, choose bA for slow cycle in the Con-  
figuration menu, step 6 (heat), 7 (cool) or 8 (heat pump).  
If an acceptable cycle rate is not achieved, contact a local  
service person for additional suggestions.  
(Air Conditioner)  
Cycles Too Fast or Too  
Slow (narrow or wide  
temperature swing)
