Jumpers in Unisab III
The Unisab III is delivered with jumpers for digital inputs.
If you do not use the below mentioned digital inputs it is necessary to use these jumpers in
order to make the compressor start and run properly without any alarms or shutdowns.

From program version 1.1.0.5 the process out and process in temperature is not fixed at
approx. 25 °C by means of pt100 dummies anymore. Now you can activate/deactivate the
temperature inputs in below picture for Chiller / Heatpump.
When choosing chiller/Heatpump = Yes the proces out temperature is automatically chosen
as yes and if necessary you can also choose proces in temperature=Yes.
If no process temperature is used, just answer no to both options.
Note!
Some of the terminal rows are very small. Do not use wires bigger than 1.0 mm2 in
the double terminal rows; X1, X3, X4, X5 and X19. Do not use a screwdriver bigger
than with a width of maximum 2.5 mm when installing these wires.
In the single terminal rows X6, X8, X10, X12, X13 and X20 it is possible to connect
wires up to 2.5 mm2.
