External Flow Proof / Off External Flow Proof / Off
Use this DIP switch to select whether or not the Flow Proof Feature is to be
used.
If the Flow Proof feature is being used, set the DIP switch to the External
Flow Proof position. The control must receive an external Flow Proof Call
within a period of time once a primary pump is turned on.
If the Flow Proof feature is not being used, set the DIP switch to the Off
position.
The flow proof call feature can only be used when the control is
configured to operate the primary pump for all loads. If there are
multiple loads (e.g. Heat Call and DHW Call) and the primary pump
is disabled for DHW operation, then the control cannot provide flow
proving and the feature must be disabled. In this case, the flow proof
feature must be obtained through another control such as the Pump
Sequencer 132. •
