Calling up code 1
Note
On weather‐compensated control
units, codes are displayed as plain
text. Codes which are irrelevant (due
to the system equipment level or the
setting of other codes) will not be dis-
played.
For heating systems with one heating
circuit without mixer and one heating
circuit with mixer, initially the possible
coding addresses A0 to d4 are
scrolled for the heating circuit without
mixer A1, then those for the heating
circuit with mixer M2.
Press the following keys:
1. K + L simultaneously for
approx. 2s.
