GENERAL INFORMATION:
This thermostat is designed to reinforce positive energy habits while limiting landlord energy expenses. For use on 208 / 240 Volt AC and a total of 16 Amps
load inductive continuous.
Almost all residential application electric heaters installed as original equipment by an electrician 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 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:
The Window Watcher ™ is a precision electronic thermostat and 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.
The Window Watcher ™ thermostat has an extra contact terminal block for remote set back to 40°F. Intended for window or door open contacts. The
40°F temperature is a fixed setting and not adjustable. The maximum operating temperature is stopped at 75°F, helping to change human behaviors that
increase energy costs. 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.
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. 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
