SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Fol-
low all local electrical codes during installation. All wiring
must conform to local and national electrical codes. Improper
wiring or installation may damage thermostat.
Recognize safety information. This is the safety alert sym-
bol . When the safety alert symbol is present on equipment
or in the instruction manual, be alert to the potential for person-
al injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies a
hazard which could result in personal injury or death. CAU-
TION is used to identify unsafe practices which would result in
minor personal injury or property damage.
GENERAL
The commercial, non-programmable thermostats are wall-
mounted, low-voltage thermostats which maintain room tem-
perature by controlling the operation of an HVAC (Heating,
Ventilation, and Air Conditioning) system. Separate heating
and cooling set points and auto-changeover capability allow
flexibility. Dry contacts are available to control the thermostat
to occupied and unoccupied set points from an external device
for energy savings.
Batteries are not required. During power interruption the in-
ternal NEVERLOST™ memory stores the thermostat configu-
ration for an unlimited amount of time.
The thermostat can be configured to accept several different
equipment configurations, including heat pump operation.
NOTE: The thermostat is not factory-configured for use in heat
pump applications. The advanced setup must be performed to
configure the thermostat for use with heat pump units.
INSTALLATION
Select Thermostat Location —
The thermostat should
be mounted:
approximately 5 ft from the floor
close to or in a frequently used room, preferably on an
inside partitioning wall
on a section of wall without pipes or ductwork
where temperature operating limits are within 41 to 104 F
(5 to 40 C)
where humidity operating range is within 0 to 95% rela-
tive humidity, non-condensing
The thermostat should NOT be mounted:
close to a window, on an outside wall, or next to a door
leading to the outside
where exposed to direct light and heat from a lamp, the
sun, a fireplace, or any other temperature-radiating
object which may cause a false reading
close to or in direct airflow from supply registers or
return air grilles
in areas with poor air circulation (such as behind a door
or in an alcove)
IMPORTANT: Read entire instructions before starting the
installation.
