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.
