7.2 Switching program 2
Switching program 2 can be used for one or several of the following functions:
• As a time switch program for the circulating pump
• As a time switch program for the release of d.h.w. heating
• As a time switch program for the multi-functional relay
Switching program 2 of the RVL471 affords a maximum of three ON periods per day.
Also, every day of week may have different ON periods.
As with the heating program, it is not the "switching times" that are to be entered, but
the periods of time during which the program or the controlled function shall be active.
Using setting "1-7" on operating line 31, it is possible to enter a switching program that
applies to all weekdays. This simplifies the settings: if the weekend times are different,
first enter the times for the entire week, then change days 6 and 7 as required.
The entries are sorted and overlapping ON periods combined.
7.3 Time of day and date
The RVL471 has a yearly clock to enter the time of day, weekday and date.
The changeover from summer- to wintertime, and vice versa, takes place automatically.
Should the respective standards change, the changeover dates can be adjusted (refer
to chapter "25 Function block "Service functions and general settings"
