The four modes of setpoint operation are described in Figure 5.
Configuring Occupancy
The TEC3000 controller supports a wide variety of occupancy sources to adapt to nearly any application.
•
Local stand-alone weekly scheduler
•
Remote schedule from BAS
•
Occupancy sensor (internal or remote)
•
Occupancy binary input (configurable)
•
Manual occupancy override
•
Temporary occupancy (by interacting with the screen while in unoccupied mode)
•
Temporary occupancy binary input
Occupancy is determined using a top-down decision matrix as shown in Table 6.

Details
Occ Setpoint Select =
Setpoint Offset and
Heat Cool Setpoint Mode =
Individual Setpoints
This is the default mode and the original mode of operation that the TEC was released with
(the next three modes are new). In this mode, the TEC has a heating setpoint 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 Select = Min
and Max Setpoints and
Heat Cool Setpoint Mode =
Individual Setpoints
In this mode, the TEC has a heating setpoint and a cooling setpoint. Each setpoint has a
configurable range (
Setpoints > Min Cooling Setpoint, Max Cooling Setpoint, Min
Heating Setpoint,
and
Max Heating Setpoint
). The configurable 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 Select =
Setpoint Offset and
Heat Cool Setpoint Mode =
Common Setpoint
In this mode, the TEC has one setpoint, Common Setpoint, for heating and cooling. There is
also a common Setpoint Offset (warmer/cooler adjust) that is only applied to Common
Setpoint. Otherwise, this setting works the same as when Occ Setpoint Select = Setpoint
Offset and Heat Cool Setpoint Mode = Individual Setpoints.
Occ Setpoint Select = Min
and Max Setpoints and
Heat Cool Setpoint Mode =
Common Setpoint
In this mode, the TEC has one setpoint, Common Setpoint, for heating and cooling. There is
a configurable range for Common Setpoint, Min Setpoint, and Max Setpoint.
