Carrier R32 User manual

  • Hello! I've reviewed the installation and operation manual for the Carrier R32 Air-to-water Monobloc Wired controller. This document provides instructions on how to use this controller to manage your air-to-water system. It covers setting the clock, adjusting operating modes, scheduling DHW operation, and checking system parameters. I'm ready to assist you with any questions you have about the device, its configuration, and operation.
  • How do I change the operating mode?
    How do I set the clock?
    How can I set the DHW schedule?
    How do I lock the buttons on the controller?

the system running parameter and display the status of system via the LCD screen.
The wired controller communicates with the IDU (Indoor unit) board with certain protocols and detect the communication
status in real time. The IDU board will activate the communication fault alarm once it loses communication. However, it will
not send the alarm if you do not connect the wired controller to the IDU board with the system power on. Hence, if the wired
controller is not necessary, please do not connect it before the system is powered on.
The wired controller will shut down its screen for saving energy without needing to press for 35s (except the technical
parameterconguration),andwillwakeupifyoupressanybutton.
Application of the wired controller:
j Power supply: Take power supply from IDU board (12V power supply);
k Working temperature range: -300~500
l Working humidity range: RH10%~95%
Wired controller can be installed inside your home or on the unit itself for split types. This manual provides guidelines
onhowtousethisinterfaceeectively.
Ifyouhaveanyquestionsregardingthedisplayanditsconguration,pleasecontactyourinstallerformoreinformation.
Caution:
• Do not press the button of wired controller for 5s after power on.
