If the system capacity requires more than one
control valve; up to three valves can be
controlled simultaneously in a Master/Slave
configuration, where the master and each slave
controls one valve respectively.
The configuration is programmed in the master
EKE 347 IO config menu - Multiple valve
setup - with one of these options:
• 2 valves with same capacity
• 2 valves with different capacity
• 3 valves with same capacity
• 3 valves with different capacity
Two identical valves (Parallel)
Valve B
The default display of the master EKE will show
the standard information together with a symbol
of multiple valves and the actual total opening
degree (see below).

Additionally the master must be programmed
in IO config menu - Multiple valve pattern - for
either:
• Valves in parallel
• Valves sequential
See principle below.
The slave EKE's only need identification of Slave
and valve CAN ID (communication menu).
Valve A
Opening degree
The default display of the slave EKE will show the
actual liquid level (as the master), symbol of
multiple valves, actual total opening degree and
the opening degree of the individual valves
involved (see below).

When more controllers are
connected via CAN bus each
end of the bus must be
terminated with a jumper
between 15 and 16.
