Remote Controller Connection
Remote controls operate at extra low voltage (12 Volts DC) which is supplied from the appliance.
Controllers are supplied with 15 m of electrical cable. The cable wires for connection to the
appliance are fitted with spade terminals.
Extension cables are available from Rinnai. Alternatively, a two core sheathed (double insulated)
flex with minimum cross-sectional area of 0.5 mm² can be used. Maximum cable length is 50 m.
For connection refer to the "CONNECTING REMOTE CONTROL CABLES" section.
Water Heater and Controller installation configurations
If there is a label on the appliance casing that contains the text "This appliance delivers water
not exceeding 50°C", local regulations may permit it's installation without a Temperature
Limiting Device. Installations without a Temperature Limiting Device are shown in Diagram 1.
If you are unsure about your local regulations contact your regulating authority or Rinnai.
If the appliance does not have this label, or your local regulations require installation with a
Temperature Limiting Device then install the appliance in accordance with Diagram 2.
IMPORTANT: If the appliance is to deliver water primarily for the purposes of personal hygiene
in an early childhood centre, primary or secondary school, nursing home or similar facility for
young, aged, sick or disabled persons as defined in AS/NZ3500.4 a Temperature Limiting Device
(TLD), such as a Tempering Valve, may be required even if the appliance is set to 50º C or less.
For these types of applications contact Rinnai.
