installed in the
supply
Swap the inner components
of the “Unibox T RTL” with the
inner components of the “Uni-
box ET” (Item no. 1022632).
Problems with the heating
system/heat generator.
Increase the pump output (if
possible).
The Duo connection piece for
two heating circuits is being
used (see Illustr. 13 on page
36).
Check the resistances of the
heating circuits. All heating
circuits must have the same
resistance.
