Connections
Warning:
Disconnect the power before
installing or changing the device wiring.
Additional Base Units
• For an installation with more than one manifold or
more than 12 channels, install additional base units
(up to three).
• A single interface drives all three base units.
• Each base unit must be fitted with an antenna.
Connections Between Base Units
STOP
The connections between the base units
are polarized.
• Base unit #1 is the controller connected to
the interface.
• Connect terminal 5 and 6 of base unit #2 to terminal
5 and 6 of base unit #1.
• Connect terminal 7 and 8 of base unit #3 to terminal
7 and 8 of base unit #1 or base unit #2.
Circulation Pump Relay
If separate pumps are used for each manifold, each pump
relay can be connected to its own base unit.
See:
Section 3: Base Unit Installation.
For a System with Several Base Units
Attention:
If a common pump supports
multiple manifolds, a pump relay can be
connected to the closest base unit. See the
circulation pump supplier documentation
before performing the connection.
