7.3 Engineering Settings
The options available in the Engineering settings are usually only required during factory assembly
and are mainly related to the functionality of the multi-temp software control.
In the instance where some install locations differ wildly from normal (eg extremely hot or cold
incoming mains water), or if a component such as a PCB or inlet solenoid has been changed, this
set of options will allow for corrections to be made so that the control software functions
properly.

Setting Option
Dispense Calibration Pressing ‘ Go! ’ – Initiates the calibration procedure for PB or UC versions.
Cal weight User measured amount of water dispensed during calibration process.
Default values (depend on machine type):
PB3 = 600
PB8 = 1050
UC3 (3 button) = 600
UC3 (1 button) = 600
Inlet Flow The software calculated amount of water through the inlet solenoid into
the boiler tank during the calibration process. NOTE: should not be
edited once calibration process completed.
Default value = 1200
Tank Factor Is a constant used in the software calculations related to the size of the
tank and whether the water is pumped or fed by gravity – default
settings are:
Default values (depend on machine type):
PB3 = 5.0
PB8 = 8.8
UC3 (3 button) = 1.5
UC3 (1 button) = 1.5
Cold Temp The temperature of the incoming mains water supply as seen at the
boiler.
Default Value = 15.0
Cold Flow The measured amount of water dispensed through the inlet solenoid fed
to the cold water dispense nozzle in 60 seconds for PB or UC versions.
Default value = 1200.
