Completing Installation
Thermostat Location
Turn off power to HVAC system.The Limit
Stat™ should be installed in a location that
represents the ambient space temperature.
Do not install the thermostat in an area where
drafts are present, near the floor, behind
doors or on an external wall. Avoid placing the
thermostat in areas where the air movement
is limited, affected by direct sunlight or other
areas not typical of the temperature in the
space.
1
Mounting the Subbase
When mounting the subbase, be aware that
drafts may travel down wall cavities and enter
the back of the thermostat through the control
wire hole in the wall. It is important to seal the
hole to prevent any drafts that might affect the
internal temperature sensor.
Pull the control wires through the large
opening in the thermostat subbase then level
and mount the subbase on the wall using the
supplied anchors and screws. Do not over
tighten the mounting screws as the
subbase may warp causing improper
seating of the thermostat connecting pins
to the terminal block.

Once all optional jumper settings have been
made, replace the batteries. Install the
thermostat on its subbase with the bottom tilted
out. Line up the two holes at the top with the two
hooks on the subbase. Slowly pivot the bottom
of the thermostat towards the subbase and push
firmly until it is securely latched.
Do not attempt to force the two halves
together.
Remove the plastic film (if present) that is
protecting the LCD display.
Turn power back on to HVAC system.
Mode Switch
The MODE switch has three positions: HEAT
and OFF. Set the MODE switch to HEAT to
control the heating system. When the MODE
switch is set to OFF, no heating or cooling will
take place.
Fan Switch
The FAN switch is not used on the LSL-HCW.
Temperature Change Buttons
When the Limit Stat™ is in the HEAT mode, a
single press on either the UP or DOWN button
will cause the LCD to display the word SET.
Once SET is displayed, the setpoint value will
start flashing. The setpoint can now be
changed by pressing or holding the UP or
DOWN button. Pressing the UP or DOWN
button will also illuminate the display for
easier viewing in dim light conditions. The
light will remain on for approximately 12
seconds.
Under normal use, the Limit Stat™ requires
no special maintenance. The LSL-HOB,
battery powered model requires that the
batteries be replaced at least once per year or
whenever the “LO BAT” symbol appears on
the LCD.
To replace the batteries, release the
thermostat from the subbase by pressing the
thumb latch located at the bottom of the unit
and swinging the thermostat up and away
from the subbase. Remove the used batteries
from the battery tray and discard
appropriately.

Maintenance
Install two new AA Alkaline batteries into the
battery tray. Match the battery direction with the
polarity markings on the battery compartment
to ensure proper operation. When finished,
replace the thermostat on the subbase by
lining up the two holes in the top of the
thermostat with the two hooks on the top of the
subbase. Slowly pivot the bottom of the
thermostat towards the subbase and push
firmly until the thermostat is securely latched to
the subbase. Do not attempt to force the two
halves together.
This thermostat must be wired in accordance

This manual is to be used by the installer only and contains
information on setting the heating setpoint limit. Avoid leaving this
installation manual with anyone who could compromise the settings.
To set the Heating setpoint limit, place the MODE switch in the OFF
position. Press and hold the UP button while sliding the MODE switch to
Heat. The LCD will display “Ht LIM”. Adjust the maximum heating setpoint

normal operation, confirm that the setpoint can not be raised above the
limit and then allow the thermostat to return to normal operation.
