Determine Primary Pump Type
The heat pump may be installed with a PWM pump (variable
speed) or a standard pump (xed speed).
To determine which type of pump has been installed, check
for connections to the control board at B1 and B6.
If the primary pump is connected at B1 and B6, it is a PWM
pump and no further action is required.
If there are no connections on B1 and B6 and the primary
pump is connected at B7 and B8, it is a xed-speed pump
and the supplied relay must be installed with the heating
pump as shown opposite.
The order in which you connect the wiring is not important.
The 2-core cable used to connect the relay to B6 and B7 on
the Samsung control board is provided.
Add a wire link between B20 and B22.
