7.4 Operation under ambient temperature (only DIGITERM
models)
The unit allows to operate at temperatures under ambient (to a minimum of +25°C)
Coolant liquid circulation is needed, through the coolant coil (See figure 7.3).
For instance, to get the bath at 25ºC, made circulate tap water through the coolant coil,
so you can get an operation temperature on 25ºC.
If tap water is under 18ºC the unit could be set the water tank to 25ºC.
7.5 External probe (only DIGITERM models)
Connect a Pt100 type probe to control the process from an external probe. The equipment
automatically detects the probe change.
NOTE: the external probe must be located at a point where the heating element takes
effect, otherwise the equipment will heat without control.
7.6 Bulb clamp change
If you are going to work at high temperatures (between 120°C and 150°C) with oils or
other liquids with a higher density than water, it is recommended to change the position
of the safety thermostat bulb to prevent the thermostat from jumping unnecessarily.
Use the attached clamping flange to modify the position of the bulb, as indicated in
figure 7.6b.
a) Remove the bulb from the retaining clips.
b) Screw it to the resistance using the attached flange.
