Heaters
The controller has a high level of logic built in to control all the hardware you have connected. So you can run 3 water heaters
independently and safely.
Controlling Three Water Heaters Independently
From the Home screen press: Settings > Hardware
> Heaters, and you will see the HEATER SETTINGS
screen, at left, where you can manage the 3 water
heaters independently. These options only show up
if you have the heaters assigned to an AC power
outlet in the Customize Outlets screen.
These settings tell the controller when to turn the
heaters on or off, when the heater is turned off the
AC power is cut to the heater so you’ll never
overheat your aquarium.
The power schedules for the heater outlets still
function however these settings override it.
*NOTE: The blue text is bright and clear on the display
Temperature Sensors
Calibrating Temperature Sensors – Water, Air & Light
** COMING SOON!
When you first connect up a temperature sensor, it will not be perfectly accurate, “out of the box”, and as such you will
need to ‘calibrate or compensate’ for the variation.
It is strongly advised that you do this as soon as you have added the sensor. You can do this by using a standard spirit
thermometer, (if you have a mercury one, please dispose of it with your local ‘hazardous waste’ facility, and replace it with
a spirit one, as mercury is a neurotoxin). The longer the thermometer, the better, (easier to read), or for more accuracy, a
NIST compliant, (12” / 30cm), spirit thermometer.
Set up the thermometer next to your temperature sensor, leave for 10 minutes, then observer the reading, the difference
between it and the reading you are seeing from the sensor, is the amount of compen/- you need to apply.
Be aware that over time, the sensor will oxidize and form a deposit on the sensor, (this will happen faster for sensors
immersed in water, than those in air), so you need to regularly check the accuracy of your reading, and every 6 months is a
good interval to check and, if necessary, adjust the amount of compensation.
Eventually, especially for those immersed in water, no amount of compensation will work, and in fact you are most likely to
start seeing ‘abnormal readings’ from your temperature sensor. When this happens, it’s time to replace the sensor.
