Error Code
CFEWH Digital operation
The unit will automatically begin operating when you turn on a hot
water tap, and water is flowing faster than 1.5 litres a minute. The
heated water temperature can be varied or set manually by using the
Decrease & Increase Push Buttons.
Temperature can be set between a
minimum of 20°C and the maximum factory set temperature of either
45°C, 50°C
OR
other Specified Maximum Setting that may be <50°C or
>50°C.
The display also shows water flow rate in litres per minute (LPM). The
minimum flow rate that can be displayed is 0.1 LPM.
When the flow rate display flashes, this indicates that the flow rate
through the unit exceeds the rated power of the unit. This can be
resolved by reducing the flow rate until it stops flashing.
