Chapter 4: E2 Controller
4.5.2.10 EHGB Status
Displays the current operating position of the electronic hot gas bypass valve.
The current suction temperature appears below. The bar gauge next to the
valve icon provides a visual representation of the output signal controlling the
valve position.
4.5.2.11 Fan Status
The Fan Status screen displays symbols indicating the operating status of the
upper, middle, and lower fans. The symbols are animated when the fans are
running. If a fan is not running, the symbol will appear instead. The value
of the proportional output signal (0 to 100%) that controls each fan appears in
the field to the right of each symbol. The animated icons are linked together
indicating the three fans are being controlled to the same fan speed setting
(default). The controller also displays the temperature value for the sensor from
each fan zone. The fans may be linked or unlinked in any combination for
individual zone temperature control (see Section 4.5.4.1).
The message “Var from Avg” or “Temp Prop” appears indicating the speed
control configuration (see Section 4.4.4.1). The message in the field is replaced
with “Dehum” when the system is in the dehumidification mode. In the
dehumidification mode, the animated icons are always linked together
indicating that the three fans are being controlled to the same
(dehumidification) fan speed setting.
4.5.2.12 Group Information Menu Screens
The Group Information menu screens only appear if the controller is set up to
operate multiple A/C unit work groups. See Section 4.6.2.8 for a more detailed
description of these screens.
4.5.2.13 Software Version/Date
Displays the type of A/C system the controller is configured for (W/G, AR), and
the Black Box software version and its release date.
