READ CAREFULLY – These instructions are written to help prevent difficulties that might arise during installation of thermostat. Studying the instructions first may save you considerable time and money later. Observing the following procedures will cut your installation time to a minimum. Save these instructions for future use.
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 wallbox.

Check the total load of the heaters you are connecting to the thermostat. The maximum wattage at 240 Volt is 5280 Watts (ESP230). If you have the 120 Volt version the maximum is 2640 Watts (ESP120). 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 circuit breaker panel and which pair lead to the heater.
With wire nuts attach the blue wire (white wire on 120 Volt model ESP120) into the pair of white wires in the junction box. (Option is red wires)
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, 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 wallbox, fasten screws at the top and bottom mounting holes attaching to wallbox. 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. The On / Off switch is located on the lower right corner to disable any operation. You have now verified the thermostat is in perfect working order.
Mounting tips: Make sure there is nothing 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 fingerprints 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 locations 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 internal battery program backup will hold all or your settings. These batteries are constantly charged and should never need to be replaced.
