Heater Control
The OmniPL provides a set of 4 low voltage dry contacts that can be connected to most gas heaters
or heat pumps with 24V control circuits. Refer to the diagram below for a generic heater connection.
The manuals supplied with most heaters also include specific wiring instructions for connecting
the heater to an external control (usually identified as “2-wire” remote control). For millivolt or line
voltage heaters, contact Hayward Tech support, 908-355-7995. Refer to the diagram on page 14
for the location of heater connections on the OmniPL Main Board. Record all connections in the
Connection Table.
External Input Interlock
The External Input Interlock provides a means to turn the filter pump or other component on/off
when certain conditions exists. A normally open or normally closed on/off external device must be
connected to the OmniPL as shown below. After properly configuring the OmniPL (see Configuration
Wizard), the filter pump and/or desired pool component(s) will be forced on or off when the device is
active.
Record all connections using the table on page 16.
