Further Information; Configuration Parameters - The Password - Carel IR32M Manual

Configuration parameters
As already mentioned, (see chapter 'How to change the operating parameters'), there are two types of
parameter:
•
parameters used frequently (indicated by 'F' in the following tables)
•
configuration parameters (type C) which are protected by a password to prevent unwanted modification.
Categorisation of parameters
Besides being divided into TYPES, the parameters are grouped into logical categories labelled by letters
indicating their function. The categories and their identifying letters are given below:
Category
Flashing 00
/
r
C
d
A
F
H
The instruments with serial number greater than 100,000 have a new software release − compatible with the
previous one − offering new functionalities described in detail in the following chapter.
The password
Flashing 00: PASSWORD
This is a protective device which intentionally "complicates" access to Configuration parameters in order to
prevent accidental changes or any that might be made by unauthorised persons. Type C parameters are in
fact those which alter the control configuration. Once the configuration parameters have been entered by use
of the password, the system allows the user to alter type F parameters as requested.
The password request (flashing 00) appears when the two buttons
time. Access to type C parameters is gained as follows:
•
press or
•
confirm with ;
•
the code of the first modifiable parameter is displayed, that is '/C'. (On controls with serial number
less than 5,000, '/O' is displayed instead of '/C' . See the relative note on page 49).
In the following paragraphs all the parameters will be described, indicating in which versions they are
available and what values can be assigned to them. (Remember that on version IR32M the parameters are
modifiable only through the remote controller and the serial input).
There will also be indicated the default value (Def.), which is the value given to the parameter in the factory.
Furthermore it will be stated whether the parameter is modifiable through the remote controller with "direct
access", that is, whether there is a specific button for modifying it on the remote controller. It should be
remembered that ALL the parameters are modifiable through the remote controller; the 16 most frequent
parameters can however be modified directly by means of a dedicated button ("direct access").
