Heating
To set the thermostat to control your heating system, press the
Heat/Cool Mode button so the word “Heat” displays. Press again
to turn off. The word “Heat” will flash when the thermostat is
calling for heat.
Cooling
To set the thermostat to control your cooling system, press the
Heat/Cool Mode button so the word “Cool” displays. Press again to
turn off. The word “Cool” will flash when the thermostat is calling
for cooling.
Configuration switch
The Gas/Elec configuration switch for heat control is located
under the top cover.
Fan
Press the Fan button to Auto to automatically run the system’s fan
during heating and cooling. Press the Fan button to On to run the
fan continuously, even without heating and cooling.
The Fan icon comes on when the manual button turns the fan on
in Auto (there is no Fan icon with the mode in Off).
If the Gas/Elec configuration switch is set to Elec, the thermostat
controls the fan with heat. The Fan icon comes on when the
thermostat turns on the fan in heat.
If the Gas/Elec configuration switch is set to Gas, the thermostat
does not control the fan in heat. The Fan icon does not come on
because the HVAC is controlling the fan.
The thermostat always controls the fan with cool. The Fan icon
comes on when the thermostat turns on the fan in cool.
When the thermostat is controlling the fan, it runs 1 minute after
shutting off the heat or cool (purging).
Displaying Fahrenheit or Celsius
To set the temperature display to Fahrenheit or Celsius, use the
F/C switch located under the top cover. Set the switch to F for
Fahrenheit or C for Celsius.
Reset
The Reset button (located under the top cover) defaults all
programming to target temperatures (heat 70
°
F, cool 75
°
F)
Using the Save Energy button
The Normal and Save Energy buttons allow you to quickly switch
from the normal programmed target temperature to a
predetermined setback temperature, called the Save Energy
temperature.
In heat mode:
1. Press the Save Energy button.
The words “Save” and “Target” appear.
2. Press the Temp Up (+) or Temp Down (-) buttons to set the
Save Energy temperature for heating (default temperature is
70
°
F).
After 5 seconds, the display shows the room temperature and
the words “Save Heat”.
In cool mode:
1. Press the Save Energy button.
The words “Save” and “Target” appear.
2. Press the Temp Up (+) or Temp Down (-) buttons to set the
Save Energy temperature for cooling (default temperature is
75
°
F).
After 5 seconds, the display shows the room temperature and
the words “Save Cool”.
To return to the programmed target heat or cool temperature
(depending on which mode you are in), press the Temp Up (+) or
Temp Down (-) buttons to change the target temperature. After 5
seconds, the display shows the room temperature. Alternatively, to
cancel save energy mode, press the Save Energy button to go
back to your previous non-setback temperature.
The Save Energy button sets back the temperature up to 4
degrees.
Joining a Z-Wave network
To join a Z-Wave network, remove the top cover and press and
release the Mate button. You will also use the Mate button when
excluding the thermostat from a Z-Wave network.
Battery operation
The thermostat batteries are not for operation, but provide battery
backup for your settings. The thermostat requires 24 VAC for
operation, and the HVAC system will stop functioning if the
thermostat loses power. Replace the batteries once per year.
To replace the batteries:
1. Change the Heat/Cool Mode button to Off and change the
Fan button to Auto.
2. Remove the bottom cover section to access the battery
compartment.
3. Remove the old batteries and insert three new AA Alkaline
batteries according to the polarity noted in the battery
compartment. (Do not use rechargeable batteries).
4. Replace the bottom cover section.
