Temperature required / alarms
Temperature is difficult to maintain at a
constant level using on and off times, so the
Bluelab Pro Controller manages it differently to
conductivity and pH.
It is normal practice to set the temperature on
time to ‘continuous’, which allows the
heater/cooler to operate until the ‘temperature
off’ value is reached.
For example, if you are heating a tank or
reservoir, when the “temperature on” value is
reached, heating will be turned on. When the
“temperature off” value is reached, it will be
turned off.
Use the Quick-set features to quickly set the “required”, “alarm high” and “alarm low”
values for all three measurements. The alarm values are taken from the actual
readings, so ensure your system is stable before using the Quick-set function.
In ‘Required / Alarms’ mode
select the measurement you
want to ‘quick-set’.
2. Press the alarm button.
3. Quick-set only sets the required
and alarm vales for the selected
measurement, so repeat steps 1
& 2 for the other measurements
required.
This table shows the values that are
applied when ‘quick-set’ is used.
