Parameter Tables
Not all parameters apply to all controller types. For example P-08 is the Superheat reference which only applies to the EEV variant of
controllers (available types on the E are 3, 4, 5 & 6). This parameter will not appear if the controller is a Mechanical variant. In the
following table, the type columns on the right hand side will be greyed out if that parameter does not apply to that controller type.
