Please read all instructions carefully before beginning
installation and save for future reference. 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.
COMPATIBILITY
The unit can be used with
most 24 volt gas, oil or electric
heating and air conditioning
systems, gas millivolt heating
systems, and single stage heat
pumps. It cannot be used with
120 volt heating systems or two
stage heat pumps. Ask your
dealer for other LUXPRO
thermostats to control those
systems.

OFF
Turn off electricity to the appliance before installing or
servicing thermostat or any part of the system. Do not turn
electricity back on until work is completed.
Do not short (jumper) across electric terminals at control on furnace or
air conditioner to test the system. This will damage the thermostat and
void your warranty.
● All wiring must conform to local codes and ordinances.
● This thermostat is designed for use with 24 volt and millivolt systems.
The thermostat should be limited to a maximum of 1.5 amps; higher
current may cause damage to the thermostat. If you are in doubt, call
your HVAC contractor.
● Your thermostat is a precision instrument. Please handle it with care.

FEATURES
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.
●
