2.4| Pre-defined applications
The purpose of the Predefined applications is to give the user an easy and fast way to configure the controller to a specific
application based on
storage temperature
(LT, MT, HT),
defrost type
(none, natural, electrical) and
defrost method
(terminated on time or temperature).
When user select specific application based on their requirements, the controller will load a specific set of parameter values
and will hide parameters that are not relevant for the selected application.
Adjustment of the set of parameters value will be still possible at any time.
In addition to pre-defined applications, all controller versions have two standard applications, one with full list of parameters
and another with simplified list of parameters, that allows the user to make their own customized parameter settings
(AP0 and AP5 in case of ERC211 and AP0 and AP6 in case of ERC213 / ERC214).
