3.1 Using the automatic summer/winter
changeover
Due to non-use in the summer months, circulati-
on pumps may become stuck. An included pump
protection program activates the circulation
pump daily at 12.00 for the duration of 1 minute.
The pump protection program is activated by
interrupting the blue wire connection within the
device. Changing the pump protection program is
not possible.
If no settings are made, the device will regulate a
constant temperature of 21° C.
The basic program and the basic regulation set-
tings will not be deleted from the memory.
Warning:
All data stored will be deleted after RESET!
If the device is in the inquiry or programming
mode and no button is pressed, the display will
automatically return to the automatic mode and
adjust to the correct switching mode after
approx. 40 sec.
