GENERAL
The 7-day, commercial, programmable thermostats maintain 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 programs for 7 independent days. Batteries are required for operation. During power interruption (batteries removed) the
internal NEVERLOST™ memory stores configuration programs 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 signal 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 programmed schedule or be configured. All configuration parameters are taken from the transmitter with Unit ID Number 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 Number 1 has a schedule and is in Program On mode, the receiver will revert back to following the programmed schedule 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 functions. Call the installer to reconfigure the security level.
