SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow
all local electrical codes during installation. All wiring must
conform to local and national electrical codes. Improper wir-
ing or installation may damage thermostat.
Recognize safety information. This is the safety alert sym-
bol
. When the safety alert symbol is present on equip-
ment or in the instruction manual, be alert to the potential
for personal injury.
Understand the signal words DANGER, WARNING, and CAU-
TION. 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 signi-
fies a hazard which could result in personal injury or death.
CAUTION is used to identify unsafe practices which would

TEMPSURE COMMERCIAL THERMOSTAT
(P/N TSTATBBP220-LA)
Page
Cancels: New
The 7-day, commercial, programmable thermostats are wall-
mounted, low-voltage thermostats which maintain room tem-
1
perature by controlling the operation of an HVAC (heating,
1
ventilation, and air-conditioning) system. Separate heating
and cooling set points and auto-changeover capability allow
1
occupied and unoccupied programming for energy savings.
2
All thermostats allow up to 4 time/temperature settings to
3
be programmed per 24-hour period. Each thermostat stores
3
programs for 7 independent days. Batteries are not required.
3
During power interruption the internal NEVERLOST™
4
memory stores programmed schedules for an unlimited time
4
while the clock continues to run for at least 48 hours.
6
The thermostat can be configured to accept several different
6
equipment configurations, including heat pump operation.

NOTE: The thermostat is not factory-configured for use in
heat pump applications. The advanced setup must be per-
7
formed to configure the thermostat for use with heat pump
7
units.

A light sensor is provided on the thermostat for light
7
activation. When the sensor detects light (the space is
7
occupied), the thermostat will enter Occupied 1 mode. If
7
the room is dark, the thermostat will follow its programmed
7
schedule.

I. 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 in-
side 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)
