1.3.3.3. DI OPTIONS (digital input options)

The DI Option you select applies to all outputs. This
option overrides any Setpoint/Setback values entered in
the Schedule.

1. Press the X button to display the DI Option selec-

tions.

2. Use the S and T buttons to highlight DISABLE,

SETBACK, or IGNORE.

Default: DISABLE

3. Press the X button to accept the value and display

the SHOW RT option.

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.

SETPOINT forces the control to the setpoint

temperature.

SETBACK enables a setback temperature value to be

programmed for each output.
— To program the Setback temperature with Reset,

see Fig. 73 on page 31.

— To program the Setback temperature without

Reset, see Fig. 60 on page 26.

ENABLE energizes all relays to 100%. Use this option

carefully.

IGNORE causes the digital input to have no effect on

the Relay or Mod outputs.
