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.
