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. Im-

proper wiring 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

CAUTION. These words are used with the safety alert sym-

bol. 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

result in minor personal injury or property damage.

GENERAL

The 7-day, commercial, programmable thermostats are wall-

mounted, low-voltage thermostats which maintain room tem-

perature by controlling the operation of an HVAC (heating,

cooling and ventilation) system. Separate heating and cool-

ing set points and auto-changeover capability allow occu-

pied and unoccupied programming for energy savings.

All thermostats allow up to 4 time/temperature settings to

be programmed per 24-hour period. Each thermostat stores

programs for 7 independent days. Batteries are not required.

During power interruption the internal NEVERLOST™

memory stores programmed schedules for an unlimited time

while the clock continues to run for at least 48 hours.

The thermostat can be conﬁgured to accept several dif-

ferent 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-

formed 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)
