Mode of Details
setpoint
operation
Occ Setpoint This is the default mode and the
Select = Setpoint original mode of operation that
Offset andHeat the TEC was released with (the
Cool Setpoint next three modes are new). In this
Mode = Individual mode, the TEC has a heating setpoint
Setpoints and a cooling setpoint. There is a
common Setpoint Offset (warmer/
cooler adjust) that is applied to each
setpoint simultaneously. The range
of setpoint adjustment is two-fold:
• There are large constant ranges
bounding the individual heating
and cooling setpoints.
• There is also a smaller
configurable range limit set to
the Setpoint Offset point (Control
Setup > General > Max Setpoint
Offset).
Occ Setpoint In this mode, the TEC has a heating
Select = Min and setpoint and a cooling setpoint.
Max Setpoints Each setpoint has a configurable
range (Setpoints > Min Cooling
andHeat Cool
Setpoint Mode Setpoint, Max Cooling Setpoint,
= Individual Min Heating Setpoint, and Max
Heating Setpoint). The configurable
Setpoints
range values are bounded by the
larger constant bounds used in
Setpoint Offset mode and are
constrained in the following manner:
Min must be below Max and Heating
must be below Cooling, so in order
from least to greatest, the values are:
Min Heating Setpoint, Max Heating
Setpoint, Min Cooling Setpoint, and
Max Cooling Setpoint.
Occ Setpoint In this mode, the TEC has one
Select = Setpoint setpoint, Common Setpoint, for
Offset andHeat heating and cooling. There is also a
Cool Setpoint common Setpoint Offset (warmer/
Mode = Common cooler adjust) that is only applied to
Setpoint Common Setpoint. Otherwise, this
setting works the same as when Occ
Setpoint Select = Setpoint Offset and
Heat Cool Setpoint Mode = Individual
Setpoints.
Occ Setpoint In this mode, the TEC has one
Select = Min and setpoint, Common Setpoint, for
Max Setpoints heating and cooling. There is a
andHeat Cool configurable range for Common
Setpoint Mode Setpoint, Min Setpoint, and Max
= Common Setpoint.

Scheduling (for all models)
The occupancy schedule comes from either the weekly
scheduler built into the TEC or as an input from the
BAS. The Schedule Source must be selected to tell the
controller where to read the occupancy source from.

Setting the local schedule

A weekly occupancy schedule with up to four occupancy
events for each day can be set locally on the TEC and
operate independently of a supervisor. See
(for all models)
Local.
Important: Internally, the TEC3000 uses a BACnet
schedule where daily schedules are independent of
the previous and next days. The default occupancy
of the TEC3000 from the factory is set to Occupied.
As a result, a daily event at 12:00 AM must be
scheduled if you do not want the controller to
transition to Occupied Mode at midnight.

Overriding the occupancy mode

The TEC supports a manual override of all other schedule
sources (for example, Schedule, Occupancy BI, and
temporary occupancy).

Enabling optimal start

The TEC supports an advanced optimal start algorithm.
The algorithm works in conjunction with a local schedule
to pre-heat or pre-cool the zone before scheduled
occupancy periods begin, in order to bring the zone
to the required occupied setpoint when the scheduled
occupancy period begins. Occupant comfort is ensured
while automatically minimizing energy usage. This
algorithm creates a model of the zone being controlled
and automatically determines when to start the
equipment before the scheduled transition to Occupied.
The start time automatically adjusts daily to minimize the
time between reaching setpoint and entering Occupied
state.
Note: Optimal Start does not work when the
schedule source is set to External.
Enabling the motion sensor (TEC3xx3
Models)
On models with integral motion sensing capability, the
motion sensor is enabled with a default timeout of 15
minutes from the last detection of motion in the zone.
On models without an integrated sensor, the default
timeout is still 15 minutes, but it only is applied when one
of the two configurable binary inputs is set to be a motion
sensor (see TEC3000 Series On/Off or Floating Fan Coil
Thermostats Installation Guide LIT-12013161 for information
about configuring the binary inputs). To disable motion
sensing capabilities, set the Motion Sensor Timeout to 0
minutes.
Scheduled circulation
You can schedule to run your fan for a minimum duration
per hour in order to maintain circulation in a space. If
the minimum hourly fan runtime is not exceeded as part
of normal HVAC operation, the fan turns on at the end
of the hour for the length of time required to fulfill the
minimum hourly run time. The fan runtime calculation
includes runtime initiated when the Fan Mode is set to
On and other overrides. The fan does not turn on if the
