During the air bleed program, the circulation pump will be alternately switched ON
and OFF for 30 sec. at a time over a period of 20 min. The burner is switched
OFF during the air bleed program. The program is activated via code "2F:1" and
automatically disabled after 20 min. Coding address "2F" is reset to "0".
If the system is to be filled with the control unit switched ON, code "2F:2"
starts the pump. The burner shuts down if this function is enabled via coding
address "2F". The program is automatically disabled after 20 min., and coding
address "2F" is reset to "0".

Additional Information
During operation with reduced room
temperature, the reduced room
setpoint temperature can be
automatically raised based on the
outdoor temperature.
The temperature is raised in
accordance with the selected heating
curve, but no higher than the standard
room temperature setpoint. The
outdoor temperature limits for the start
and end of the temperature raising can
be adjusted via coding addresses "F8"
and "F9".
