ROTATIONAL CONTROL CONNECTED TO HSS BUFFER TANK
If your using the Rotational Control Panel (BDCB-RC4HP) with the B&D HSS Buffer Tank Controls, the main HSS Control
Box Board (B3-6CR) XY,XR,XY terminals will need to communicate to the Rotational Control Board (BDCB-RC) demand
signal contacts.
See below for the location of the 3 wires that need to be run from the main HSS Control Box Board (B3-6CR)
XY,XR,XY terminals to the Rotational Control Board (BDCB-RC) demand signal contacts.
The main HSS Control Box Board (B3-6CR) requests demand for hot/cold water based on its current controls method. XY
terminal closes on HSS B3-6CR Main Board sending the power it receives from the Rotational Board (BDCB-RC) XR
terminal back to the Rotational Board (BDCB-RC) XY terminal.
This will start a water device. The water device that is started depends on where it left off in its rotational control
program. The device that is on has a light designating that it is actively running. This then starts the Rotational Controls
functionality.
