Low Voltage Wiring - Hayward OnCommand Installation Manual

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.
Generic Heaters
1. Wire heater to 120/240V power source per the instructions in the heater manual. The OnCommand does
NOT control the power going to the heater.
2. Wire the OnCommand dry contact heater output per the diagram below. Many internal parts of the heater can
get very hot--see the heater manufacturer's recommendations on the minimum temperature rating for wires. If
no guidance is given, use 105°C rated wire.
3. Set any ON/OFF switch on the heater to ON.
4. Set the thermostat(s) on the heater to the maximum (hottest) setting.
