4a. To connect a 2-Wire Control (such as Pentair’s IntelliTouch® or EasyTouch® Control
Systems) or a timer:
- Remove the factory installed jumper from the Fireman’s Switch terminals.
- Connect wires between the Fireman’s Switch terminals on the heater and the relay.
Connect wires from the controller or timer to the Fireman’s Switch.
Controller, timer or relay should be sized to handle 24VAC at 0.5 Amp (because it will be completing the 24VAC control board circuit on the heater as shown in Figure 22).
DO NOT apply line voltage to the Fireman’s Switch terminals.
Use 18 gauge wire with a minimum 3/64” (1.2mm) thick insulation rated for a temperature rise of at least 105°C.
- Knock-outs are provided to route the wires through the bottom of the control box and past the junction box.
4b. To connect a 3-Wire Control:
- Connect wires between the control board terminals on the heater and the external relays, as shown in Figure 23.
Use at least 2 relays per heater, to allow for an “OFF setting” on each heater mode.
Select relays that can handle logic level switching.
DO NOT apply line voltage to control board terminals.
- Move jumper (as shown on Figure 23) to enable external control and to disable the heater membrane pad’s “Pool ON” and “Spa ON” buttons (the “OFF” key on the membrane pad remains functional).
- Knock-outs are provided to route the wires through the bottom and the top of the control box and past the junction box.
5. Close control box cover.
