CAREL IR33+ CONTROLLER
Programming Instructions
The Carel IR33+ controller has a two-level menu system for programming the operation of the case; Level 1 and Level 2 program settings.
Unlike IR33, the IR33+ control system is easier to use with a password.
HOW TO CHANGE LEVEL 1 AND 2 CONTROL SETTINGS
1.
Press and hold the [PRG] button down until the display shows a flashing "0".
2.
Use the [UP] arrow until the display reads "22" (this is the password), then press the [SET] button. The display will read "/A2".
Use the [UP] and [DOWN] arrows to move up or down the menu until you reach the parameter you intend to view or change. When the
3.
proper code is displayed, press the [SET] button to view the current setting for that parameter. (You will notice the Level 1 program codes
are also found in this menu.)
4.
Use the [UP] and [DOWN] arrows to change the value. Then press the [SET] button again to return to the menu.
5.
The exceptions to Step #4 are the program codes "tc", "td1", and "td2". In these cases, you must press the [SET] button in order to
access the submenu of available settings for these parameters. Once changes are made in this submenu, press the [PRG] button to get
back to the main menu.
6.
When finished making all necessary changes, you MUST press and hold the [PRG] button for 10 seconds to save them. Alternatively, if
you decide you do NOT want to save changes you've just made, simply stop pressing buttons for 30 seconds and the control will return to
normal operation, discarding any changes made.
Note: Zero Zone should be contacted before working on changing settings. To be completed by a trained person only.
