CAREL ASD100 PGD1AY0I00 User Interface Panel for HVAC Controllers

Product Overview

The CAREL ASD100 PGD1AY0I00 (also known as PGD1000I00 or PGD1000100) is a user interface terminal designed for use with CAREL programmable controllers, particularly in HVAC (heating, ventilation, air conditioning) and refrigeration applications. This operation panel provides a graphical display and keypad for local monitoring of system parameters, setpoint adjustment, alarm viewing, and configuration. It connects to the controller via a serial communication link (typically CAREL’s tLAN or pLAN protocol). The ASD100 series is known for its robustness and ease of use in commercial building automation and industrial climate control.

Key Features of PGD1AY0I00

The panel features a backlit LCD graphic display with 128 x 64 pixel resolution, capable of showing alphanumeric characters, bargraphs, and simple icons. It includes a 6-button membrane keypad (up, down, enter, escape, and two function keys) for menu navigation. The display can show real-time values of temperature, pressure, humidity, and status of connected equipment. The panel allows operators to view and edit setpoints, schedules, and alarm thresholds. The enclosure is rated IP65 for front panel protection against dust and water jets, suitable for washdown areas.

The PGD1AY0I00 communicates with CAREL controllers using a 4-wire RS-485 connection (tLAN protocol) at baud rates up to 19200. The panel is powered directly from the controller via the communication cable (24 V AC/DC). The maximum cable length is 300 meters. The panel includes configuration parameters for device address and contrast. It supports multiple languages (selectable). The unit has non-volatile memory for storing settings. The overall dimensions are standard for panel mounting (approx. 100 x 100 mm cutout).

Functional Description

The panel communicates with the CAREL controller via tLAN. When powered, it identifies itself and requests data from the controller. The user navigates through menus that are defined in the controller program; each menu item can display read-only values or allow write access to setpoints. The panel sends commands to the controller when the user changes a value. The controller can also push alarm messages to the panel, which shows an alarm icon and text. The backlight can be set to turn off after a period of inactivity to extend display life.

Applications

This operation panel is used in air handling units, chiller controls, rooftop units, refrigeration racks, and supermarket control systems. It serves as a local operator interface where access to a central BMS is not available.
