• If the Relay Output was set to Pump, the System relay will energize whenever the outdoor
temperature is below the outdoor Cutoff in heating or above it in cooling. See "Relay
Output" on page 12. When the outdoor temperature increases 2°F above the outdoor Cutoff
or when the EXT+ and EXT- terminal inputs are opened, the output relay will stay on for
the Run-On period. This allows the system to dissipate the residual energy within its units
back into the system.
• The Run-On time should be set based on the size and type of the equipment controlled.
