CONTROLS

Introduction

The WeatherExpert ™ 50LC*H features the Carrier SmartVu
control system, which controls and monitors the unit operation.
This manual provides basic, step by step guidance on control setup
and unit operation for typical applications. For more detailed
information, refer to the Controls, Operation, and Troubleshooting
guide on HVACPartners (HVACPartners.com) or Carrier.com/
commercial.

Overview

The SmartVu control system includes multiple control boards and
a touchscreen interface, which can be found in the control box.
See Fig. 46 for control box location and Fig. 51 for typical control
box layout. The SmartVu controls include multiple standard and
optional factory-installed sensors. See Table 5 for sensor listing
and Fig. 47-49 for sensor locations.

Control Interface

TOUCHSCREEN DISPLAY

The SmartVu touchscreen display is the primary method of in-
™
terfacing with the controls for setup and equipment start-up. The
touchscreen is a capacitive 7 in. LCD that can be activated with a
finger, touch compatible gloves, or stylus. See Fig. 52 for display
layout and port locations.

WEB BROWSER

The SmartVu controls can be accessed using a hardwired ethernet
connection and a web browser. See Fig. 52 (SmartVu touchscreen
display) for internet port locations. See Table 4 for default IP
addresses.
Once the hardwired connection is established between the com-
puter and the control, open a web browser, and enter the default
address to access the control. The user interface should appear on
the web browser.
NOTE: The web UI connection may be detected as a non-secure
connection by your web browser. If so, use the advanced menu op-
tion on the web browser to acknowledge and accept the connec-
tion.

LEGACY CONTROL INTERFACES

The SmartVu controls are not compatible with legacy Carrier con-
trol interfaces, such as the Navigator
Touch ™ , or System Touch ™

NAVIGATION

The interface operation method is the same for both touchscreen
and web browser use and is typical of a touchscreen interface, like
a smartphone or tablet. Clicking on specific icons or buttons will
perform an action. See Table 6 for a list of the interface buttons re-
lated to navigation.
Screens can contain multiple pages of information. When addi-
tional pages are present, the page up/down button will be dis-
played at the bottom of the screen and the number after will show
as two or more. Pressing the page up/down button will scroll
through the available pages. See Fig. 50 for an example of a screen
with multiple pages.
