(System Pump operation ONLY)
• If the display shows dno then the BCP-6/12 will not have a DHW priority.

DOWN button to toggle between the displays of dno and d_P.

can not compute a calculated water temperature below this setting, and can not have
a set point value below this.

McLain representative.

pushing either the UP button to increase the value, or the DOWN button to decrease
the value.

wait approximately 5 seconds.
