all ’variomat’ controllers. If you want to make changes beyond the scope of the customer
menu, please contact Reflex Service (tel. +49 (0) 23 82 / 70 69-550 or -512). You will find
a partial overview of the parameters stored in the service menu in the following table.
The following default values are set in the ’variomat’ on delivery. The values marked with an ’x’ under “Customer menu” can
be changed. A vessel size of 800 l is set if no VG basic vessel size was specified when ordering.
