Emergency Mode: If the Transducer fails the WPC will stop. This is done to prevent possible over pres-
surising of the system. Because a Transducer isn’t a device which is readily available in all parts of the world an
Emergency Mode has been provided to enable the unit to run from a pressure switch.
To acvate Emergency Mode:
1. Turn o the power and wait unl the screen is dark .
2. Connect a Pressure Switch between terminals 1 & 2 (It doesn’t maer whether you leave the pre-installed
white wire in terminal 2 or not.)
3. Turn on the power and the unit will now detect the Pressure Switch, it will respond by acvang its emergen-
cy mode and act as an on/o controller in response to the input from the pressure switch.
