The 284 requires a closed switch or short for proof of flow. Up to 24 V (ac) can be passed through the
switch. If a flow proof device is being used, ensure the External Flow Proof / Off DIP switch on the front
of the control is set to the External Flow Proof position.
Connect the Flow Proof Call terminals 1 & 2 to the flow proof device.
If a flow sensor is being used as the flow proving device, a jumper must be placed across the
flow proof call terminals.
