Configuring the thermostat controller
Use the Menu icon on the home screen to access and change the basic operating parameters of the thermostat
controller. During normal operation, press the Menu icon once to access the following parameters:
Installer configuration menu
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.
Screen reset
The current screen returns to the home screen and turns off if the current screen is not touched for 3 minutes.
Touch the screen to turn it on again. To disable the screensaving option, press Display Settings and set Enable
Display Timeout to No.
Selecting the unit type
There are three unit types. They are:
• 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.
By default, the thermostat controller is configured for four-pipe fan coil mode. To change to a two-pipe or
Pressure-Dependent VAV mode:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press General.
5. Press Unit Type and select 2-pipe, 4-pipe, or VAV.
6. Press
Save and the back arrow to return to the previous screen.
Note: Selecting VAV reboots the controller in order to apply the change.
Configuring the supply fan - fan coil only
On fan coil units (two-pipe or four-pipe), three different types of supply fans are supported. These are single-speed
fans, multi-speed fans (up to three discrete speeds), and VSF using a 0 to 10 V control signal and an optional
binary on/off command. Note that fan control is not available when in VAV mode. To select the fan type:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
