System Pump operation
• Dip switch 1 must be ON.
• If an outdoor sensor is not connected or registers a fault condition:
- The SYSTEM output will be energized when any OUTPUT stage is energized.
- After the last OUTPUT is turned off, the SYSTEM output will remain ener-
gized for the period of time set by the System Delay and then turn off.
• When the control is set for “no DHW priority” (see pg. 9) and there is a call for
DHW:
- With the outdoor temperature below the Outdoor Starter, the SYSTEM
output will be active.
- Otherwise, the SYSTEM output will be off (after the System Delay has
expired).
• When the control is set for “DHW priority” (see pg. 9):
- For the first hour of a DHW call, the SYSTEM output will be off.
- After the first hour, when the outdoor temperature is below the Outdoor
Starter setting, the SYSTEM output will be active.
- When the outdoor temperature is above the Outdoor Starter, the SYSTEM
output will be off at all times.
• The SYSTEM contact has a single pole double throw (SPDT) output.
• The SPDT output is capable of switching 6A resistive at 120VAC.
• If the System Pump output has not been activated for 7 days (as might occur in the
summer), the SYSTEM relay will be energized for 15 seconds to exercise the pump.
INITIAL FRONT PANEL SETTINGS
Set before Power Up
• Each stage which is to be active (and has a relay installed) should have its OFF/
AUTO/ON switch in the AUTO position.
• Any stage which is not to be active (or any stages without output relays) should
have its OFF/AUTO/ON switch in the OFF position.
• Set the LEAD STAGE switch in the AUTO position for automatic rotation.
SETTING THE OPERATING PARAMETERS
On Power Up
• Whenever the BCP-6/12 is powered up, it displays the software version number and
then the operating parameters. Each display will remain on the screen approximately
5 seconds. If the parameters are correct, there is no need to make any adjustments.
• There are no adjustable parameters when using the BCP-6/12 to control pressure.
• Once the parameters have been set for a particular application, they will be retained
in memory and will not need to be reset.
• Note that if you do change a parameter, you will need to reset all the settings.
• A parameter can only be changed in the start-up sequence. To restart, it is neces-
sary to remove and reapply power.
• Set the parameters as described in sequence below:
°F or °C - Fahrenheit or Celsius Temperature Operation
• If the display shows °F then the BCP-6/12 will operate in Fahrenheit degrees.
• If the display shows °C then the BCP-6/12 will operate in Celsius degrees.
• To change the operating parameter, hold down the center button while pushing
either the UP or DOWN button to toggle between the displays of °F and °C.
• When the correct temperature display parameter is selected, release the buttons and
wait approximately 5 seconds.
