The thermostat controller comes from the factory with default settings for all configuration
parameters. The UI menu navigation and default settings are shown in Table 13. Before any
outputs turn on, the controller must be configured for the equipment connected. You need to start
from the home screen to perform any of the following tasks.

Selecting the unit type
About this task:
The following three unit types are available:
• Four-pipe—This unit type has both heating and cooling coils plus a supply fan. This configuration
can also be used on configurations that are heating or cooling only.
• Two-pipe—This unit type has a single set of pipes that can serve hot or chilled water plus a
supply fan. The Supply Temp Type allows for the connection of an analog sensor or an aquastat
to a binary input. Based on the water temperature or aquastat state, the unit controls heating or
cooling.
• VAV—This unit type is designed for a pressure-dependent zone damper and the supply fan
outputs are disabled. The TEC senses the supply air temperature coming from the unit.
The Supply Temp Type setting allows for the connection of an analog sensor or binary duct
thermostat. Based on the air temperature or duct thermostat state, the zone damper controls for
heating or cooling. The TEC does not control the unit delivering the air. The logic needs to be part
of another controller.
