General information:
This thermostat is designed to provide the highest level of accurate temperature
control for residential line voltage electric heating in 120 or 208/240 volt. Almost
all electric heaters installed as original equipment in a residential application will
be 208 or 240 volt. It is very rare that a home, apartment or condominium would
be wired with all 120 volt heaters. Check your voltage to make sure you have the
right thermostat for your heater voltage. A 2 pole or double wide circuit breaker at
the panel would indicate that you should use the 240 volt model. A single pole or
single wide breaker would indicate a 120 volt circuit. There are some exceptions
to this rule so checking with a voltmeter is the only way to know for sure. Be safe
and smart, electricity can cause severe injury or death.
The thermostat will provide years of comfort control for your family for small fan
driven electric heaters, baseboards, radiant ceiling, wall panel heaters, cove
heaters, or any line voltage resistance heating systems that do not have an
electric motor over 1/3 hp. The thermostat will be warm to the touch on top. This
the electronics operating, it also provides air currents across the face of the
thermostat that help it sense room temperature better.
Operation:
This precision electronic thermostat will sense the room air at the bottom of the thermostat by a thermistor. This very sensitive sensor will send
information to the microprocessor. As the temperature drops, the information it sends will indicate if heat is needed. To reduce any undesirable fast
on/off cycles, the processor has a built in 1 to 3 minute delay. This will save energy and provide the best control of a space. This thermostat dose not
require batteries and will have a default setting of 68°F when powered up. It is easily changed by tapping the arrow keys on the front of the
thermostat. Up arrow increases temperature and down arrow reduces temperature. Backlighting is provided on some models and can be turned off
or on by a small switch under the left corner of the thermostat. This will allow you to see the thermostat in low light or at night.
Installation:
This line voltage device should be installed and serviced by a qualified electrician. The thermostat has been designed to mount to a standard 2” x 4”
electrical outlet box. Leveling of the thermostat is not required. Mounting screws are provided. Mount the thermostat about five feet above the floor
in an open area in the living room. A good rule of thumb is to place the thermostat above the wall switch for that room. This works well for most
bedroom and makes it very convenient to turn the heat lower when leaving the room. Avoid mounting the thermostat where there may be plumbing
pipes in the wall or placing a lamp or TV too close to the thermostat. The heat from these items affects the thermostats performance.

Thank you for buying this King Thermostat. It should provide years of service and comfort to your home. Inspect the package. You
should have received the thermostat with its cover and two screws to attach it to a wall box.
Check the total load of the heaters that you are connecting to the thermostat. The maximum wattage at 240 Volt is 5280 Watts. If you have the 120
Volt version maximum is 2640 Watts. You need to stay below this total wattage connected to the thermostat. The lower the wattage the longer the
life of the contacts in the relay.
To wire the thermostat determine which pair of wires are coming from the breaker panel and which pair lead to the heater.
Attach, with a wire nut, the blue wire (white wire on 120 Volt model ES120) into the pair of white wires in the junction box.
Use black lead from the Circuit Breaker panel and attach it to the black lead on the thermostat. This will provide power to the thermostat and LCD
display and backlight.
Attach black lead going to the heater to the red lead on the thermostat. This will provide power to the heater when the thermostat calls for heat.
Remove thermostat cover by holding back of thermostat with one hand and grasp the top and bottom of the cover with the other hand, pulling
towards you evenly.
Push the wires carefully into the junction box making sure no wires will be pinched when attaching to the wall using #6-32 screws provided.
Holding thermostat into wall box, fasten screws at the top and bottom mounting holes attaching to wall box. (Do not over tighten screws)
Turn on power to test. Increase set point to higher than current room temperature by tapping the up button. There will be up to a 3 minute delay in
turning on. The red indicator will turn on and you will here a small click as the heater energizes. Turn the thermostat down by tapping on the down
arrow.
To turn on backlighting: Under the bottom left of the thermostat, you will feel a small switch. Moving one way will turn on the light and the other
will turn off the backlight. You have now verified that the thermostat is in perfect working order and ready for years of trouble free operation.
Mounting tips: Make sure there is not anything that could affect the average room temperature sensing of the thermostat such as plumbing pipes
in the wall, a lamp close by, direct sunlight, a T.V. set, and/or cold drafts from a door opening.
Cleaning: A damp cloth will clean the plastic case surface of finger prints and dust. Strong spray cleaners may damage plastic case, remove
writing or arrows printed on case. Blow out any dust that may accumulate on air vents on top or bottom. Good air circulation is key to long life and
accurate operation.
Humid locations: Mildly humid location like bathrooms may see a reduced life due to corrosion on the contact and lint from towels getting into air
vents on thermostat. Blow out vent regularly and mount thermostat away from shower locations for longer life.
Power outages: The thermostat will default to the 68 degree factory setting.

Fahrenheit to Celsius:
On the bottom edge of the thermstat, there are air
vents. In one of the vents on the left side, just
behind the illumination switch, there is a larger
opening with a pin collector attached. With needle
nose pliers, pull the connector off. This will put
the thermostat into the metric Celsius mode.
