Setting the over temperature control.
There are two methods of setting the over temperature cut out:
Option one. (Quick method)
Set the temperature to the required value and leave the bath to stabilise for a least 5
minutes after the set point has been reached. Turn the control slowly anticlockwise,
using a screwdriver, until the alarm lamp comes on. Press the reset and at the same
time turn the control slowly clockwise until the alarm lamp goes out. This gives an
over temperature trip point of approximately 10° to 30° C above set temperature.
Option two. (Precision method)
Set the temperature to the cut out level required and leave the bath to stabilise for a least
5 minutes after the set point has been reached. Turn the control slowly anticlockwise,
using a screwdriver, until the alarm lamp comes on. Allow the bath to cool, then press
the reset button and the unit will start. (Bath will have to cool by 15° to 30° before
the reset will work). This gives a over temperature trip point of the set value. Now
decrease the set temperature to the working set point.
