Heating zone controller E8
The R600 can be extended with an E8
controller for extended control of two
heating zones and sanitary hot water
operation. The E8 combines weather
compensated operation with control of
two heating zones and the control of a
secundary hot water circulation pump.

Further details about the electrical connections can be found on the wiring diagram.
In case of heating systems with more
than two heating zones, an additonal kit
with E8 in a wall hung box is available.
These kits can be used in a modular
way up to a maximum of 15 heating
zones. For room temperature optimisation of
each heating zone, an additional roo-
munit BM8 can be connected via bus
connection. The values for the specific
heating zone can then be displayed
and changed on the room unit.
