B4 Outputs for Heating, Dosing equipment and Backwash
The B4 connector allows for the ControlPro to be connected to:

The ProValve automatic backwash Valve, connect the 'backwash' terminals to the pilot valve and a 230V
power source.

A heater or heat pump can be connected on the 'heater' terminals. Most heaters will have a contact to
connect an external control system. If this is not the case, interrupt the flow switch on the heater and
connect it to the 'heater' terminals on ControlPro

The 'dosing' output can be used to activate water treatment equipment (UV lights, dosing pumps, Salt
Chlorinator) while the filtration is running. Output is interrupted during backwash and at low temperatures.
(see the 'Configuration' chapter in this manual)
Make sure not to apply more than 8 amps over any of the ControlPro contacts. Failure to do so will damage
the system and is not taken under warranty. Use a contactor if the application requires higher current.
