Low Voltage Wiring - Hayward OnCommand® Installation Manual

Hayward Variable Speed Filter Pump: Proper installation of the Hayward TriStar Variable Speed Control
(VSC) includes high voltage input wiring, communication wiring, and menu configuration/settings. Refer to the
following diagram for proper input wiring to the VSC. Wiring from a 240V breaker must connect through the
OnCommand's Filter relay. The Filter relay is used to supply input power to the VSC pump control. The relay will
be on when the filter pump output is on. When the filter pump output is off, the relay will be off. Note that when
the filter pump relay is off (power off to the VSC), the OnCommand will not display errors or diagnostics for the
pump. The filter pump relay must be on for diagnostic function.

Low Voltage Wiring

Valve Actuators
The OnCommand can control up to three automatic valve actuators. Two of the valve outputs are dedicated to the
pool/spa suction (Valve2) and return (Valve1) valves. Valve3 is for general purpose use (solar, water feature, in-
floor cleaner, etc.).
For installations with solar heating, Goldline offers the AQ-SOL-KIT-xx solar kit that contains a valve, actuator,
and extra temperature sensor. The "xx" indicates the valve type from the choices below:
-1P 1.5" Positive Seal
-2P 2" Positive Seal
The OnCommand is compatible with standard valve actuators manufactured by Hayward, Pentair/Compool, and
Jandy. See diagram on page 5 for the location of valve connectors.
Heater Control
The OnCommand provides a set of low voltage dry contacts that can be connected to most gas heaters or heat
pumps with 24V control circuits. Refer to the diagram on the following page for a generic 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 Goldline Tech
support, 908-355-7995. Refer to the diagrams and the information on the following pages for more details on the
connection to several popular heaters.
