Before starting, to avoid damage to electrical components, switch off
and remove the power plug of the water heater.
Do not fix or permanently attach either the transceiver or controller
until you have tested that both are working correctly.
Rinnai Wireless Transceivers can be connected to the water heater models listed by the end
user in accordance with these instructions. A licensed tradesperson is not required. A licensed
tradesperson is only required if connecting more than 2 cables. This installation would normally
be a wired/wireless installation, where more than 1 wired controller is fitted in combination
