Caution:
Temperature setting 41 degrees F to 90 degrees F (5C to 30C)
The thermostat can be adjusted between 41 degrees F and 90 degrees F
by simply rotating the soft dial clockwise to raise the set point or
counterclockwise to lower the set point, The selected set point appears
on the right side of the display. The room temperature is the larger
readout that appears in the middle of the display. (fig. 3)
High/Low Limits
The ES100 will automatically cutoff in the heat mode if the temperature
rises above 90 degrees F, and automatically cutoff in cool mode if the
temperature drops below 41 degrees.
Low Temperature Hazard.
Operating at too low of an outdoor temperature may
cause compressor damage.
Do not operate cooling if outdoor temperature is
below 50F(10F). Refer to manufacture's
recommendations.
Compressor Protection
If a call for cooling is made before the compressor has been off for five
minutes, or if a power interruption occurs while the compressor is
running, the thermostat will go into a five (5) minute delay before the
compressor can be restarted. This feature will prevent damage to the
compressor caused by rapid cycling.
Set system running cycles
Use the switch marked with "CY5M" & "CY2M" (fig.2 )
in the middle of Setting pin switches to set system running cycles.
At CY2M side: maximum 'I cycle per 2 minutes.
At CY5M side: maximum 1 cycle per 5 minutes.
Backlight and battery warning
The backlight activates when the backlight button is depressed or when the dial is
rotated.
The two fresh AM Alkaline batteries should provide well over one year of service.
However, when the batteries become drained, the low battery indicator will appear on
the lower right display. When this message occurs, install new batteries. Once the
batteries have become too low to ensure proper operation, the system will be turned
off, and the display will be cleared except for the low battery indicator on the display.
Caution:
When only the low battery icon is displayed, the thermostat will shut down,
and the system will no longer operate. In this condition, there is no
temperature control of the dwelling
Note: If the homeowner plans to be away from the premises over 30 days, we
recommend that the batteries be replaced prior to leaving.
To replace batteries: The batteries are located in the back of the thermostat body. (fig. 4)
Follow the instructions below under "Mounting the Thermostat" to remove the
thermostat body from the subbase. Remove the old batteries and replace with two (2)
new AM Alkaline batteries. Gently replace the thermostat body to the subbase by
positioning the bottom clips on the thermostat into the subbase. Then align and push
together the black pin receptacle on the back of the thermostat body with the white
pin receptacle on the subbase. Then press and latch the top of the thermostat into the
top of the subbase.
Remove old thermostat
Caution: Do not remove any wiring from the existing thermostat before reading the
instructions. Wiring must be labeled prior to removal.
Important: Turn off the power to the furnace at the main power panel or at the
furnace.
Wiring labeling
Each wire coming from the wall to the existing thermostat is connected to a terminal
point on the thermostat. Each terminal point is usually marked with an alpha letter.
The number of wires in the system can be as few as two (2) (for heat only systems.
There is often no terminal marking on the existing thermostat of two (2) wire, heat
only systems. Just conned either stills wires to the Rh terminal, then connect the
other wire to the W terminal to complete the circuit).
Important: Before disconnecting any wires, apply the self-adhesive labels provided,
to the wires, since the wire colors cio not always comply with the standard alpha letter
terminal designations.
Separating and attaching switching subbase with thermostat body
Hold the thermostat body and depress the top center of the thermostat with your thumb or use
a screwdriver to depress the indent. Gently pull down and outward to separate the thermostat
from the subbase. Determine the desired meathod of installation from Fig.1 or Fig.2
Typical system wiring diagrams
Important:
Use only 18-gauge thermostat wire. All wiring must comply with local electrical
codes and ordinances. Disconnect the power supply to prevent electrical shock or
damage to the thermostat or equipment.
