Adjustment of parameters
Using the programming menu, you will be able to configure the various parameters in order
to adapt the controller's operation to the needs of its installation.
In order to access the programming menu, press the PRG key for 5 seconds, or until the
message ''PwD'' is displayed. Using the N and Q keys enter the password (programmed
into the PSS parameter) and press SET. Once entered correctly, the password will not be
requested again for 30 minutes.

*The default value of the password is 5. This may be changed using the PSS parameter.
Table of parameters
The equipment's operation functions are divided into 3 different groups.
The Def. column indicates the default parameters set in the factory. Temperature values are
expressed in ºC. (Equivalent temperature in ºF) and the pressure values in bar (equivalent
pressure in psi).
