WARNING! – USE THE SAME PHASE WHEN CONNECTING TO 3 PHASE POWER
If 3-phase power is being used, care must be taken to ensure the same phase is used to power both the heater and the filtration
controller. Failure to connect both power supplies to the same phase will result in damage to the heater and tripping of the
electrical circuit breakers.
MOTORISED VALVE ACTUATORS
Models 200, 280, 350, 430 Only
Up to two 24V AC motorised diverter valves may be wired to the terminal strip included with the above heater models. This must
be completed by a licensed electrician. A relay switches supply between the Red and White wires connected to the terminal strip
when the MODE button is pressed. In Pool mode the Red wire terminals will be provided with 24V and the White wire terminals 0V.
Following connection of the valves to the terminal strip, the valves will be activated each time the MODE button is selected (See
Motorised Valves
).
Motorised Valve Connection Details
1. Isolate the heater from all power sources.
Caution:
Two 240V power connections may be present. Ensure both are disconnected before continuing.
2. Remove the heater front door.
3. Thread the 24VAC motorised valve actuator wires through the side of the heater via opening provided.
4. Connect the wires into the terminal strip as required (See diagram).
Note:
With “Jandy” valves and most other brands a Red, White and Black wire will be present. In most cases colours should be
matched with the factory terminal connections. Any pin
type connector at the actuator wire end will need to be removed to enable
direct connection to the terminal strip.
5. Once all connections are made and the door has been replaced, the heater should be reconnected to the electrical supply and
the motorised actuators checked for correct positioning when the MODE button is selected. If necessary direction of valve
actuation may be varied by swapping Red and White wires at the
terminal strip.
