MOUNTING OMEGA
Wall Mounting
1. Attach the mounting
bracket to the wall using
two screws
2. Position the Omega
controller onto the
bracket
3. Verify the bracket
is fully inserted into the
controller slot

12 13
Valve Mounting
1. Remove the bolt and
nut from the valve
2. Attach the bracket adapter plate to
the valve using the bolt and nut which
were removed
NOTE: The bracket adapter
plate provided by BERMAD
is designed for horizontal
installations, and is suitable
for the BERMAD 200 series
valves without further need for
adjustments


14 15
3. Insert the mounting
bracket into the Omega
controller
4. Verify the bracket
is fully inserted into
the controller slot
6. Verify the bracket
adapter plate clicks in place
and is securely fastened to
the mounting bracket
5. Position the mounting
bracket onto the bracket
adapter plate

16 17
Pole Mounting
1. Attach the bracket adapter plate to the
U-clamp using a bolt and nut
NOTE: The U-clamp is an
optional accessory that must
be ordered separately. The
U-clamp provided by BERMAD
fits 1” (DN25) to 2” (DN50) pole
diameters

2. Attach the U-clamp
to the pole using two nuts

18 19
5. Position the mounting
bracket onto the bracket adapter
plate
6. Verify the bracket adapter
plate clicks in place and is
securely fastened to the
mounting bracket
3. Insert the mounting
bracket into the Omega
controller
4. Verify the bracket
is fully inserted into
the controller slot

POWERING OMEGA
Battery Power Supply
The Omega controller is powered by four LR-14
(C-size) alkaline batteries (see battery datasheet in
full manual)
Insert four batteries according
to the orientation shown in the
battery compartment
CAUTION: Running the Omega
controller on battery power in
online mode shortens battery
life significantly
NOTE: In offline mode, the
controller can run on battery
power for up to five years

Tip: For best performance
in outdoor installation, use
batteries with an operating
temperature range of
-18° to 55° C or greater

22 23
External Power Source
The Omega controller can be powered by electrical
grid power, external high-capacity batteries, or
solar panels
CAUTION:
• Connect the power cable to
the Omega power connectors
before turning on the power
source
• The Omega controller must
first be unplugged from the
external power source before
disconnecting the power
supply cables from the power
connectors
NOTE: An external power
supply is necessary if operating
the Omega controller in online
mode for an extended amount
of time

Verify the power supply
provides 9-24 VDC/1 A
Verify the external power source
polarity matches the polarity marked on
the connector board

CONNECTING PERIPHERALS
Latch Output Connections
Up to five devices (such as valves and water
pumps) can be connected to the Omega controller
latch outputs
NOTE: The Omega RS model
features up to four latch
outputs and one RS-485
MODBUS

Pump
Latch
relay

Activated via 25
ms pulses
Latch solenoid valve
A relay must be
connected between the
latch output and the
pump

26 27
Digital Input Connections
Up to four devices (such as water meters and
digital sensors) can be connected to the Omega
controller digital inputs.
NOTE: Digital inputs can be
connected to devices with
one of the following outputs:
- Dry contact
- Open collector

CAUTION: Ensure the open
collector connects according to
the input polarity marked on
the connector board.

28 29
Analog Input Connections
Up to two devices (such as the following types of
analog sensors) can be connected to the Omega
controller analog inputs.
NOTE: The controller supports
both analog voltage (0-10 V)
and analog current (4-20 mA)
sensor

CAUTION: Ensure setting the
correct analog protocol before
connecting the sensor
