Swap the inner components
of the “Unibox T RTL” with the

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

Check the resistances of the
heating circuits. All heating
circuits must have the same
resistance.
