TEMPERATURE CALIBRATION
It is possible to calibrate the temperature of your chiller to match another piece of equipment, such as a high
precision thermometer/temperature controller/aquarium computer, or to create an offset to match the water
temperature in the aquarium if the chiller is remotely positioned.
Press the
and
together and hold for 6 seconds. It is then possible to adjust the reading up or down
through 1.5 degrees in 0.1 degree steps.
If this function is not specifically required, then we suggest that you leave the reading at factory setting.
CHILLER PROTECTION SYSTEM
A protection system is built into the chiller which prevents the refrigeration compressor from starting for three
minutes between cooling cycles during normal operation or after a reset or when in use for the first time. If used
with a third-party external temperature controller then the chiller will see this as a reset and delay for 3 minutes
before starting the compressor.
AUTOMATIC ON & OFF SWITCHING OF THE REFRIGERATION COMPRESSOR
When the refrigeration compressor has not been running for over three minutes and the water temperature is
1 ºC above the set temperature, the compressor will start to work again automatically.
The compressor will continue to run and cool the water then stop working automatically when the aquarium
water temperature reaches or falls below the set temperature.
The indicator light (7) shows that the chiller is working. The light turns off when the aquarium water temperature
reaches the set temperature & the compressor stops running, the light twinkles to show that the protection
device is delaying the compressor from restarting for three minutes.
FAULT DISPLAY SYSTEM
Some breakdowns will automatically show on the display. When the water temperature sensor is broken the
letter. P1/(E1 – DC4000 model) will appear on the display and the protection device will respond to stop the
chiller. E2 – DC4000 MODEL will be shown if the defrost circuit is not working.
