When the digital input (DI) closes, all outputs follow the DI option value (Disable, Setback, or Ignore):

•DISABLE disables the outputs; relays return to de- energized state and Mod outputs return to 0% output.

•SETBACK enables a setback temperature value to be programmed for each output.

—To program the Setback temperature, see Fig. 32 on page 16.

•IGNORE causes the digital input to have no effect on the Relay or Mod outputs.
