Thank you for buying this King
Window Watcher ™ thermostat. It should provide years of service and comfort to your home. Inspect the package.
Enclosed should be the thermostat with its cover and two screws.
1. Check the total load of the heaters being connecting to the thermostat. The maximum wattage at 240 Volt is 3840 Watts, 208 Volt is 3328 Watts,
and 16 Amps. It is important to stay below this total wattage when connecting the thermostat. Lower wattage prolongs the the life of the contacts
in the relay.
2. To wire the thermostat determine which pair of wires are coming from the breaker panel and which pair lead to the heater. See Wiring Instructions.
3. Remove cover of thermostat by placing thumb on LCD display and fingers on top edge of cover. Pull towards you. This will expose the top
mounting screw.
4. There may be a pair of white wires connected in your junction box. If so, leave them alone and, at this time, work with the black wires.
5. Take a black lead and attach it to the black lead on the thermostat.
6. Take the other black heater lead and attach it to the red lead on the thermostat. This will provide power to the heater when the thermostat calls
for heat. Add blue wire to both white wires to provide power to electronics.
7. Push the wires carefully into the junction box making sure no wires are pinched or will obstruct the screws mounting the thermostat. Now attach
the thermostat to the wall using the #6-32 Phillips head screws provided. Replace cover. Do not over tighten screws.
8. Replace cover after setting time and programming.
9. Turn on power. Test by increasing 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. You will hear a small click and “Heater On” will appear in the LCD; the heater should be on now. Turn the thermostat down
by tapping on the Down arrow.
10. You have now verified the thermostat is in perfect working order and ready for years of trouble-free operation.
11. Mounting tips: Make sure nothing is nearby (a.g. plumbing pipes in the wall, a lamp close by, direct sunlight, a T.V. set, and/or cold
drafts from a door opening) that could affect the average room temperature sensing of the thermostat. Typically the best, most convenient
location is on inside walls above the light switch for that room.
12. Cleaning: Canned compressed air works great to clear any dust accumulation, while a damp cloth will additionally clean the plastic case surface
of finger prints. Strong spray cleaners may damage the plastic case or remove writing or arrows screen-printed on case. Blow out any dust that
may accumulate on top or bottom air vents. Good air circulation is key to long life and accurate operation.
13. Humid locations: Mildly humid location like bathrooms may reduce life due to corrosion on the contact and lint from towels getting into
thermostat air vents. To extend life blow out vent regularly and mount thermostat away from shower locations.
