1.3 Accessories
1.3.1 Chiller user terminal
For DIN rail mounted models (built-in on the panel model). The user terminal includes the display and keypad, comprising four
buttons that, when pressed alone or combined with other buttons, access the operations available for the “User” and “Service”
profi les (see the paragraph on “Commissioning”). Connectivity - NFC or NFC + Bluetooth (BLE) based on the model - allows inter-
action with mobile devices and simplifi es unit commissioning (after having installed the CAREL “Applica” APP for the Android
operating system, see chapters “Commissioning” and “User interface”). For assembly, see the technical leafl et +0500146IE.

1.3.2 pGDx Touch user terminal
The 4.3” pGDx graphic terminal is part of the touch screen family designed to make the user interface simple and intuitive. The
electronic technology used and the 65K colour display enable management of high quality images and advanced features to
ensure a high aesthetic standard. The touch screen display guarantees simple human-machine interaction, making it easier to
browse between the various screens. See the technical leafl et +050001895.
Code Description
PGR04****B*** pGDx, 1 x RS485 port, 1 x 24 Vdc power connector, 1 optional
keypad connector
PGR04****C*** pGDx, 1 x opto-isolated RS485 port, 1 x 24 Vdc power connector, 1
optional keypad connector, 1 Ethernet port

1.3.3 EVD Evolution/EVD Evolution twin valve driver
The Enhanced and High Effi ciency models have the driver built-into the controller, able to drive unipolar valves (up to Carel
model E3V, with a cooling capacity less than 90-100kW); all versions can be connected to the external EVD Evolution driver to
drive bipolar valves (with a higher cooling capacity).
