6. NETWORK CONNECTION

6.1 WIRING CONNECTION RINNAI NETWORKERS

The Rinnai Networker backing plate has 4 terminal points for the connection
of Thermostat wires. When connecting, use the top 2 terminal points marked
TW1 and TW2 or the bottom 2 terminal points also marked TW1 or TW2.
Never use a combination of terminals when connecting to a single appliance.
For example; A Rinnai Networker operating a cooler and a heater would
have the 2 bottom terminals connected to the heater and the 2 top terminals
connected to the cooler.
Run a twin wire cable (i.e. figure 8 cable - 0.75mm2) from the Cooler to the
Rinnai Networker.
•
Remove the backing plate from the Rinnai Networker by unclipping it at the
sides.
•
Draw the wires from the wall cavity and feed them through the opening in
the backing plate, connect the cable to the terminal connections on the
backing plate before mounting it on the wall and re-assembling the Rinnai
Networker.
•
Connect the cable to the Rinnai Networker connection lead terminal block
at the Cooler.

6.2 INSTALLING DUAL RINNAI NETWORKERS

It is possible to have two Rinnai Networkers connected together on a system.
The Rinnai Networkers should be wired in parallel, never in series (see
diagram of typical wiring). The two Rinnai Networkers are identified as either
Master or Slave. All Rinnai Networkers come set as Master by default, and the
slave Rinnai Networker will need to be configured upon installation.
Both Rinnai Networkers cannot be set as Master on a system
otherwise it will malfunction. Both Rinnai Networkers cannot
be set as Slave otherwise the system will lock out.
NOTE

6.3 DUAL RINNAI NETWORKERS

Adjustments to the cooler settings can be made from either Rinnai Networker; but the settings are common to
both Rinnai Networkers. If an adjustment is made on one Rinnai Networker it is immediately reflected on the other
Rinnai Networker.
When the cooler is operating in AUTO mode, the Master Rinnai Networker only will be sensing the inside comfort
level, unless the cooler has been designated to the Slave. This means the Master Rinnai Networker should be
located in the most appropriate location to control the inside comfort level.
Once the location for the Master and Slave controllers has been determined, the Rinnai Networker addresses
should be configured. All Rinnai Networkers come set as Master by default, which means only the Slave Rinnai
Networker needs to be configured.
A Master Rinnai Networker can be identified by the word "clock" beside Key 5 (while the Rinnai Networkers are in
the off position). Initially, both Rinnai Networkers upon power up will have the word "clock" beside key 5, because
they are both still Masters at this stage.
