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.

is used to identify unsafe practices which would result in minor

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.
