: OUT OF RANGE message
This error message will be shown (see Fig.16) in case of temperature
sensor failure or in case if the temperature inside flow tube is outside
of the measurement range of the sensor (0-100°C). During the
winter time temperature could drops below 0°C.
Possible cause 5:
SHUTDOWN HIGH AMBIENT message (see fig.17)
The
heater is fitted with intelligence sensors not only monitoring water
temperature but also the temperature within the electrical enclosure. To
protect your components if the temperature inside the enclosure reaches
60°C, the controller will shut down and go to STAND BY mode. This could
be due to the product being exposed to direct sun light, operating in very
hot environment. As soon as the temperature drops down the heater will
come back on to heating mode automatically.
