Master And Slave Addressing; Wiring The Manual Wall Control; Setting Up Multiple Coolers On The Network - Rinnai A20 Installation Manual

6.4 MASTER AND SLAVE ADDRESSING

•
Press the clock Key 5, and across the top a scrolling message should
say "Clock setting mode", and after the message has finished the time
will begin flashing.
•
Push and hold Keys 2 & 4, until the screen displays this message "Installer
parameter access"
•
After the message has finished, push the Mode key until the screen
displays - n01 ID00:1 at the top (see diagram).
•
Rotate the circular dial to change the parameter value displayed at the
top right of screen to the number required for the Slave e.g. Slave=2.
•
Once this parameter value has been set, push the ON/OFF button to exit
this Installer set-up program.
This Rinnai Networker will now become the Slave Rinnai Networker, and the installer parameters can no longer
be accessed from this Rinnai Networker. The Master Rinnai Networker MUST now be used to access the installer
parameters.

WIRING THE MANUAL WALL CONTROL

After the Cooler's power supply and pre-wired wall control leads are fed
down from the base into the roof cavity, connect the 20-metre wall control
loom plug to the cooler's lead plug.
•
Ensure the wall control is positioned so that it is within reach of the cooler
using the 20-metre wire loom assembly supplied.
•
Wall Controls accept the polarised plug connection. The Manual wall
control has a small loom to connect the polarised plug to.

6.6 SETTING UP MULTIPLE COOLERS ON THE NETWORK

To ensure each Cooler is configured correctly to the Rinnai Networker
see the instructions below and refer to the Rinnai Networker Advanced
Programming Manual No. 400 (Available on request from Rinnai Customer
Service).
As the Rinnai Networker is polarity sensitive when more than one Cooler is
installed on a Rinnai Networker all the Coolers should be wired in parallel
(see diagrams above).
To ensure each Cooler is configured correctly to the Rinnai Networker, each
Cooler MUST BE:
•
Given a different specific identification number, starting at No. 1.
•
Designated to a zone (refer to the Rinnai Networker Advanced
Programming Manual No. 404).
Each Cooler comes with the ID number set at number 1. To give it a new
number, first complete the installation and wiring of all the units, as described
previously and follow the instructions on the next page. (Changing an
Identification Number)
