Initial Operation:
1. Fill the water heater with water
before turning on the electrical
supply.
2. Turn on the electrical supply.
3. The Hotlogic
®
controller will initialise.
During this period LED 1 and LED 2
will blink alternately red/green.
(The Hotlogic
®
controller is visible
through the grill on the top of the
water heater).
4. Once initialisation is complete,
LED 1 and LED 2 should be a
steady green.
5. The Hotlogic
®
controller will
check the temperature of the
water in the tank and the ambient
air temperature. The Hotlogic
®
controller is self-regulating. No
adjustments are required.
6. If conditions are suitable, the
compressor and fan will start. This
will take approximately 30 seconds
from the time the electrical supply is
turned on.
7. If the compressor and fan do not
start, check if LED 2 is flashing red
or LED 3 is a steady red. Contact
Dux After Sales and Service if
required.
Conditioning Cycle:
When the water heater is operated
for the first time, it runs through a
conditioning cycle.
It will not reach full temperature until
approximately 60 litres of water is drawn
off and the water heater completes a
second heat-up cycle.
