WARNING: The fan controllers contain high voltage capacitors that take time to discharge after removal of mains supply.
Before working on the fan controller, ensure isolation of mains supply from line inputs at the fan controller’s disconnect
if installed. Wait three (3) minutes for capacitors to discharge to safe voltage levels. Darkened display LEDs are not an
indication of safe voltage levels.
The following parameter changes are required for proper operation:

Fans recommends making the parameter changes listed above prior to remote wiring or jumper wire installation. Jumpers
should be installed between terminals 1 and 17, terminals 13B and 13C, and terminals 12V and 16. If an ESFR pilot relay is already
installed on terminals 12V and 13A, remove the N.O. relay common lead from terminal 12V and relocate to terminal 16. This will
prevent three wires from being landed under a single terminal. In this control arrangement, terminals 12V and 16 are both +12 VDC for
digital supply.
Both jumpers (1 to 12V, 1 to 13B) must be removed if present!
