GENERAL INFORMATION:
This thermostat is designed to provide the best temperature control for residential line voltage electric heating. For use on 120 / 208 / 240 Volt AC and a total of
16 Amps load inductive continuous. This is a single pole thermostat with a double pole switch to disconnect both legs of power to the heater.
Almost all residential application electric heaters installed as original equipment by an electrician will be 208 or 240 Volt. It is very rare and uprofessional that a
home, apartment or condominium would be wired with all 120 Volt heaters. Check the voltage to make sure you have the right thermostat for your heater
voltage. A 2-pole or double-wide circuit breaker at the panel indicates a 240 Volt circuit; A 1-pole or single-wide breaker indicates a 120 Volt circuit. There are
some exceptions to this rule; Check with a voltmeter to determine accurate phase to phase voltage.
Be safe and smart! Electricity can cause severe injury or death if not treated with respect and caution.
This thermostat will provide years of comfort control for your family in use with small fan-driven electric heaters, baseboards, radiant ceiling or wall panel
heaters, cove heaters, or any line voltage resistance heating systems that do not have an electric motor over 1/3 hp.
OPERATION:
This precision electronic thermostat uses a very sensitive thermistor near the bottom to sense room air temperature, sending the information on to the
microprocessor. As the temperature drops, the information sent will indicate if heat is needed. To reduce any undesirable fast on/off cycles, the processor has a
built-in delay, up to 3 minutes. This saves energy and provides the best temperature control of an area.
This thermostat requires batteries and will have a one minute back-up when replacing old batteries. ECP only: The default program setting is 62°F set back,
70°F set up and a standard work week timing when powered up. The day and time of day can be adjusted by selecting the TIME position and using the
arrow keys. For an override, the UP arrow increases temperature and the DOWN arrow reduces temperature without any need to readjust the
programming. When “OFF” button is pressed the backlight will go off indicating both hot leads are disconnected.
The thermostat may take a few hours to stabilize the room temperature; Do not be alarmed when the thermostat does not show the correct temperature
immediately after installation.
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. King recommends a 21 cubic inch junction box for new installation. Leveling of the thermostat is not required. #6-32 Phillips head mounting screws
are provided.
Mount the thermostat in an open area about 5 feet above the floor, avoiding outside walls as they are too cold and will inhibit the thermostat’s performance. A
good rule of thumb is to place the thermostat above the wall switch for that room. This works well for most bedrooms, making it very convenient to turn the heat
lower upon leaving. Avoid mounting the thermostat where there may be plumbing pipes in the wall, or placing a lamp or TV too close to the thermostat. Heat
from such items negatively affects the thermostat’s performance.
