There is a small magnet in the flow cell that is held in place with a piece of tape. Remove the tape and
make sure the magnet remains in the hole above the filter / strainer. If using a digital flow sensor the
magnet will not be needed.
IMPORTANT NOTE:
There needs to be enough flow (0.5 gpm) through the flow cell to raise the flow
magnet inside the flow cell to make contact with the flow sensor. To test this, turn the “input” shut-off valve
to the off position and watch the flow magnet drop from the flow sensor. Next, turn the input shut-off valve
back on and watch the flow magnet rise to the flow
sensor. If the flow magnet rises abruptly and
pings/knocks the flow cell acrylic then the flow is
too high. To reduce flow, perform the same
exercise, but now open the shut-off valve slowly
and stop when you see the magnet “slowly” rise to
make connection with the flow sensor. Leave the
shut-off valve in that position.
Sensor Wire Connection
If not pre-mounted, route the pH (Blue Sensor
Wires), ORP (Red Sensor Wires), flow sensor and
temp sensor wires through the cable grips at the
bottom of controller and connect as labeled inside
the controller.
Note: Black wires are always
negative (-) and the Clear or Red wires are
always positive (+).
REQUIRED
Flow Sensor Connections:
Connect flow sensor wires for pool #1 to flow
�
Optional Flow Sensor Connections: Flow switch
2 & 4 are auxiliary switches for Pool #1 and Pool
#2 respectively. For powered 3 wire digital flow
meters or water level indicators use the 18VDC
connection on the left of the main board, note
that it has a 1 amp fuse.
Supply 110/240 Vac Input Selection
The PoolWarden supports both 110 VAC and 240 VAC. For 110 VAC the power cord includes a GFCI on
the end of the cord that plugs in. For 240 VAC the cord should be removed and the PoolWarden should be
hardwired to a circuit breaker with a GFCI by a licensed electrician. The cord can be returned to
ControlOMatic for a credit.
�
VAC Selector:
The red switch in the center of the bottom circuit board must have the switch notch up
for 110 VAC, and down for 240 VAC. Incorrect selection will damage the PoolWarden.
�
A good solid earth ground is required for PoolWarden to work properly. Without a solid ground
connection the sensors may drift.
�
The ORP and pH relay are directly connected to the input VAC. If you have the PoolWarden set for 240
VAC then the loads must also be 240 VAC.
For 240 VAC operation, the neutral line will be connected to the Red 240 VAC wire and the Line
connection will be to the Black 240 VAC wire. The Neutral connection for pH and ORP relays switches
the Neutral input VAC wire. The relays are double pole double throw and break both lines.
