Setting The Control Mode; Setting The Fan Mode - Fan Coil Only; Configuring The Zone Space Or Equipment Size - Johnson Controls TEC3000 Series Quick Start Manual

Setting the Control mode

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.

Setting the Fan mode - fan coil only

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 is dependent on the fan type. The following
options are provided for single- and variable-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 following Fan Mode options are provided for multi-speed fans:
• Low—Fan is continuously on low
• Medium—Fan is continuously on medium
• High—Fan is continuously on high
• 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- and variable-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.
The following Fan Override options are provided for multi-speed fans:
• Low—Fan is continuously on low
• Medium—Fan is continuously on medium
• High—Fan is continuously on high
• 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

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.
Changeover
Pressure-Dependent VAV systems and two-pipe fan coils require changeover detection in order to switch seasonal
operation between heating and cooling modes. The TEC supports the following methods for changeover:
automatic changeover using an analog sensor (thermistor), automatic changeover using a binary switch, or remote
changeover from a BAS and manual changeover.
