GENERAL
The 7-day, commercial, programmable thermostats main-
tain room temperature by controlling the operation of your
heating, cooling, and ventilation system. Separate heating and
cooling set points and auto-changeover capability allow you
to program schedules for energy savings.
All thermostats allow up to 4 time/temperature settings to
be programmed per 24-hr period. Each thermostat stores pro-
grams for 7 independent days. Batteries are required for op-
eration. During power interruption (batteries removed) the
internal NEVERLOST™ memory stores configuration pro-
grams for an unlimited time. The clock will need to be reset
every time power is lost (batteries removed).
The wall mounted or hand-held transmitter sends its sig-
nal to a receiver installed near the HVAC unit. Each paired
transmitter and receiver can be given a separate house code
for multiple thermostat applications. Up to 4 transmitters can
send information to 1 receiver device.
If more than one transmitter is used with a single receiver,
the transmitters must be given different Unit ID Numbers.
Only the transmitter with Unit ID Number 1 may have a pro-
grammed schedule or be configured. All configuration pa-
rameters are taken from the transmitter with Unit ID Num-
ber 1. Transmitters with Unit ID Numbers 2, 3, and 4 cannot
be programmed or configured (except for set points).
When more than one transmitter is used, the receiver will
only accept commands from the transmitter that was last used
(button pressed). All other set points and modes from other
transmitters are ignored. If the transmitter with Unit ID Num-
ber 1 has a schedule and is in Program On mode, the re-
ceiver will revert back to following the programmed sched-
ule when a time period change occurs, even if the transmitter
with Unit ID Number 1 is not the current commanding
transmitter.
IMPORTANT: The transmitter has a configurable security
level. If certain functions are not available (changing set
points, changing programming schedules), the transmitter
security level may be configured to exclude those func-
tions. Call the installer to reconfigure the security level.
