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 haz-
ard 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 fan coil programmable thermostats are wall-mounted

or unit-mounted, low-voltage thermostats which maintain
room temperature by controlling the operation of a fan coil
unit. Separate heating and cooling set points, auto-changeover
capability, 2 or 4-pipe configurability, and single or dual set
point options allow for greater flexibility.

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™ mem-
ory stores configuration settings for an unlimited time while
the clock continues to run for at least 48 hours.

The thermostat can be configured to accept several different

equipment configurations, including 2 or 4 pipe operation.

The temperature display range of the thermostat is 35 to

99 F (2 to 36 C).
NOTE: The thermostat is factory-configured for use in 4-pipe
applications. The advanced setup must be performed to config-
ure the thermostat for use with 2-pipe applications.

OPERATION

Thermostat Display — 

 

The thermostat display is locat-

ed in the center of the thermostat. See Fig. 1. The following
information can be displayed on the screen:

time

mode (OFF, HEAT, COOL, Program On, or AUTO)

fan setting (auto, low, medium, or high)

room temperature

desired temperature

setup indicator

lock indicator

programming indicators

schedule indicators

outside sensor indicator

Heat or Cool Indicator — 

A Heat or Cool indicator is

located on the bottom middle cover of the thermostat. See
Fig. 2. The light will be red if the thermostat is in Heating
mode. The light will be green if the thermostat is in Cooling
mode.

Thermostat Front Panel Buttons — 

The thermo-

stat has buttons on the front cover which are used to raise or
lower the desired set point and change the current mode. See
Fig. 2.
