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.
See previous page 10 for the 1st and 2nd stage lighting identification of the Rotational Board (BDCB
