The Energysaver remote switching kit is a remote switching relay
that allows an external control to switch the unit on and off. Ideal for
commercial applications such as schools, community halls, churches etc.
This kit is for AC 24 V use only. Please ensure that the
connection to the terminal from outside is AC 24 V input. If it
is not AC 24 V the PCB will not work and you risk damaging the
sub-PCB.
Before starting ensure the power and gas supplies are
disconnected.
Kit suitability and contents
The R1349 kit is suitable for Rinnai’s current range of Energysavers
(309FT, 559FT, 561FT, 1005FT) and also some older models (556FTR,
557FTR). Only information for our current range is included with this
guide. Please adapt the information as necessary if you are fitting the
kit to an older model. The steps will be the same, only the attachment
positions will differ (refer wiring diagrams inside appliance).

WARNING
1. Disconnect the power supply from the wall.
2. Remove louvre and front panel.
3. Attach the circuit board spacers to the sub-PCB, then attach to the
rear panel. For the 1005FT you will also need to relocate the main
PCB (two screws) to allow access to the rear panel.
4. Using the screws provided, attach the terminal to the rear panel.
5. Connect the sub-PCB and main PCB with the sub-PCB lead wire.
6. Connect the central timer harness to the sub-PCB, feeding it
through a hole* in the rear panel.
7. Connect the central timer harness to the terminal by pressing the
lever down, inserting the end of the harness into the connection
point of the terminal, and switching the lever back to its original
position.
8. Connect the outside signalling wire as in step 6 and reconnect the
power supply.
9. Test the PCB by turning it on at the on/off switch (ensure central
timer is also in an ‘on’ cycle) to check that the heater starts. Turn
24 V signal off to check that the heater stops.
10. Re-attach the louvre and front panel.
* Hole has rounded edges so a bush or protection is not required. Bush provided in the kit
does not fit any of the current models.

Each Energysaver has a specific position to attach the sub-PCB and
spare port to attach the sub-PCB lead wire. Refer overleaf for images
for each model. You can also refer to the wiring diagrams—folded
inside a pouch in each unit.
Removing the louvre and front panel—the 1005FT has seven screws.
