Htr.SpareFigure 15. PCB with firmware REV N or higherDo not connect more than two (2) wires to any of theterminals in the Control System when connectingperipheral devices. If connecting the heater to the controlsystem creates this situation, then a Multiplex PCB Kit,which includes the Multiplex Board (part # 6584) must beused. Call Jandy Technical Support at 800.822.7933 withany questions.NOTE: Only an AquaLink® RS System with firmware revision “N”,or higher, will support the heater interface. Refer to Table 5 alongwith Figure 14 and Figure 15 to determine the REV of your system’sfirmware. If it is “N” or higher, continue with these procedures. If it isMMM or lower, follow the procedures in Section 7.2 for connectingto a remote TSTAT.NOTE: Only a PDA System with firmware revision 4.1, or higher,will support the heater interface.• Use 22 gauge 4-conductor wire to run between theheater and the RS control and match the wire colororder. See Figure 13.• The wires coming from the heater can be “doubledup” on the red terminal bar with the four wires fromthe indoor controller.• Check all wiring, then apply power to both the heaterand the control system. Verify operation in eitherService or Auto mode. Refer to your Control Systemmanual for operating instructions.When the heater is connected to an external controller,all functionality of the heater control panel is disabled,therefore heater functions can be controlled only from thecontroller. |
