•
On—Fan is continuously on
•
Auto—Fan cycles on demand with the controller entering cooling, heating, or dehumidification modes
•
Smart—Fan cycles on demand with the controller entering cooling or heating modes during unoccupied
periods but is continuously running during occupied and standby periods
The Fan Override icon on the home screen is dependent on the fan type. The following options are provided for
single-speed fans:
•
On—Overrides the fan to be continuously on
•
Auto—Follows the behavior set as Fan Mode
•
Quiet—Follows the behavior set as Fan Mode, but prevents the fan from ever going above minimum speed.
The Quiet option has no effect on equipment with single-speed fans.
Configuring the zone space or equipment size
With non-binary outputs, the TEC3000 is configured by default to have a slower temperature response for larger
zones with normal-sized equipment. In installations with small zones and oversized equipment, set the Equipment
Size parameter to Oversized.
Temperature setpoints
The thermostat controller provides a flexible setpoint configuration to give power to the building owner while being
easy to use by the occupant. In addition to a simple up/down offset adjustment on the home screen for the
occupant, there are six temperature setpoints on the TEC. The six temperature setpoints are Cooling and Heating
setpoints for Occupied, Unoccupied, and Standby modes.
Note: The TEC enforces a 2-degree deadband between heating and cooling setpoints. If a setpoint violates this
standard (for example, cooling setpoint is set to 70 with a heating setpoint already set to 70), the opposing setpoint
is modified to comply with this deadband (in the previous example, the heating setpoint would automatically
change to 68).
The four modes of setpoint operation are described in Table 5.

Details
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).
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.
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.
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.
