dno or d_P - NO DHW Priority or DHW Priority
(System Pump operation ONLY)
If the display shows dno then the BCP-6/12 will not have a DHW priority.
If the display shows d_P then the BCP-6/12 will disable the SYSTEM output for the
first hour of a DHW call.
To change the priority, hold down the center button while pushing either the UP or
DOWN button to toggle between the displays of dno and d_P.
When the correct priority is selected, release the buttons and wait approximately 5
seconds.
Minimum Water Temperature
The display will next show the minimum water temperature setting. The BCP-6/12
can not compute a calculated water temperature below this setting, and can not have
a set point value below this.
DO NOT lower this below the default setting of 140°F without contacting your Weil-
McLain representative.
To change the minimum water temperature, hold down the center button while
pushing either the UP button to increase the value, or the DOWN button to decrease
the value.
When the desired minimum water temperature is selected, release the buttons and
wait approximately 5 seconds.
SETTING THE CONTROL PARAMETERS
After the Startup Sequence
Settings shown have been selected by Weil-McLain and will provide
proper operation for most installations.
After the startup routine has completed, the display will show the system water
temperature or the system steam pressure.
To display the other control parameters, repeatedly press the center SELECT
SETTING button.
Check the appropriate chart on the next two pages to find the list of control param-
eters for each application.
A parameter can only be adjusted when it is being displayed.
Use the UP and DOWN buttons to adjust the setting.
The display will always revert back to the actual system temperature or pressure
after 30 seconds.
