Setting the Control mode
About this task:
The Control Mode informs the controller to run in Cooling
only, Heating only, or Automatic mode, based on the
temperature in the zone relative to the heating and
cooling setpoints. Control Mode does not override
equipment lockouts or changeover. To set the Control
Mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Control Mode and select Cooling, Heating,
or Auto as preferred.
5. Press Save and the back arrow to return to the
previous screen.
Setting the Fan mode
About this task:
The Fan Mode informs the controller how to handle
the fan. There are two options for fan configuration: a
Fan Mode available to the installer through the menu
system, and a fan override available as an option to the
end user from the Fan icon on the home screen. See
Customizing the home screen for information on enabling
and disabling end-user controls. The Fan Mode available
to the installer depends on the fan type. The following
options are provided for single-speed fans:
• 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 depends
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.
To set the Fan Mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Fan Mode and select On, Auto, or Smart.
5. Press Save and the back arrow to return to the
previous screen.
Configuring the zone space or
equipment size
About this task:
With non-binary outputs, the TEC3000 default
configuration is 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.
To set the Equipment Size parameter, complete the
following steps:
1. Press the Menu icon.
2. Press Control Setup.
3. Press Tuning.
4. Use the up and down arrows to navigate to
Equipment Size.
5. Press Equipment Setup and select Oversized.
6. Press Save and the back arrow to return to the
previous screen.
Temperature setpoints
About this task:
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.
To set these setpoints, complete the following steps:
1. Press the Menu icon.
2. Press Setpoints and then Temperature.
3. Select the setpoint to adjust and change as
preferred.
4. Press Save and the back arrow to return to the
previous screen.
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).
Result
The occupant has access to an up/down adjustment from
the home screen. This adjustment applies a fixed offset
(+/-) to the currently active setpoint, and this offset holds
until the occupancy state of the controller changes. If
the user taps the setpoint on the home screen, the icon
inverts and displays white text on a black icon. The offset
is held throughout all occupancy periods. For example,
if the TEC is cooling in Occupied mode to an occupied
cooling setpoint of 72 and you raise the setpoint 2
degrees to 74 from the home screen and then select hold,
then the +2 degree offset persists through an occupancy
change. If the occupancy then changes to unoccupied,
