14.7 Potentiometer (Adjusting the Setpoint)
The PIM Ignition Control will continue to operate the Heatstation boiler at a 140 degree internal factory setpoint should
the touch screen control fail, or communication between the two devices is interrupted. This internal setpoint can be
adjusted using the potentiometer to maintain a different operating temperature under these circumstances if desired.
If this scenario occurs, the PIM will revert to the supply sensor (outlet sensor) for temperature regulation.
