Thermostat Setting
The thermostat is adjustable from 60°C to 75°C. Turning the adjustment knob anticlockwise decreases the
temperature setting and turning it clockwise increases the temperature setting. Rinnai advice that the thermostat
be set at 65°C, this temperature is sufficient for most users. Ensure the power supply is switched OFF before
removing the access cover to the element and thermostat.
• The access cover to the element and thermostat must only be removed by an Electrician or
other suitably qualified trades person.
• The thermostat setting must only be adjusted by an electrician or other suitably qualified
trades person.
• After adjustment, press the (red) ‘Reset’ Button on the thermostats to ensure the over-
temperature and energy cut-out is set.
