Convert "Unibox E RTL" from
a return flow temperature
limiter to an individual room
temperature control ("Unibox
T"). For this purpose, use the
"Unibox T" conversion kit.
Problems at the heating sys-
tem/heat source.
Increase the pump output (if
possible).
Use the duo connector for two
heating circuits (see Illustr. 11
on page 35).
Check the resistance values of
the heating circuits. All heating
circuits must have the same
resistance.
