Service plans
A number of service operations are grouped in plans, called
Service plans A, B or C. Each plan has a programmed time
interval at which all service actions belonging to that plan are
to be carried out.
When reaching the interval, a message will appear on the
screen indicating which Service plans are to be carried out.
See "User manual for Elektronikon regulator", section "Status

After servicing, the intervals are to be reset. See "User manual
