IMPORTANT!
Please read all instructions carefully before

Before removing any wiring from your existing thermostat, its wires
must be labeled with their terminal designations.
Ignore the color of the wires since they may not comply with any standard.
Thank you for your confidence in our product. To obtain the best results from
your investment, please read this manual and acquaint yourself with your
purchase before installing your new thermostat. Then follow the installation
procedures, one step at a time. This will save you time and minimize the chance
of damaging the thermostat and the systems it controls. These instructions may
contain information beyond that required for your particular installation. Please
save for future reference.

THERMOSTAT LOCATION
On replacement installations, mount the new thermostat in place of the old
one unless the conditions listed below suggest otherwise. On new installations,
follow the guidelines listed below.
●
Remember that your PSD111 may be mounted vertically or horizontally when
determining the optimal location.
●
Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor,
and in a room that is used often.
●
Do not install it where there are unusual heating conditions, such as: in
direct sunlight; near a lamp, radio, television, radiator, register, or fireplace;
near hot water pipes in a wall; near a stove on the other side of a wall.
●
Do not locate in unusual cooling conditions, such as: on a wall separating an
unheated room; or in a draft from a stairwell, door, or window.
●
Do not locate in a damp area. This can lead to corrosion that will shorten
thermostat life.
●
Do not locate where air circulation is poor, such as: in a corner or an alcove;
or behind an open door.
●
Do not install the unit until all construction work and painting has been
completed.
