3.3.5.3. 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  button to display the DI Option selec-
tions.
2. Use the  and  buttons to highlight DISABLE,
SETBACK, or IGNORE.
Default: DISABLE
3. Press the  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 and forces the control to
the setback temperature.
— To program the Setback temperature with Reset,
Refer to Fig. 34 on page 15.
— To program the Setback temperature without
Reset, Refer to Fig. 43 on page 18.
• ENABLE energizes all relays and MOD outputs to
100%. Use this option carefully.
•DHW: If a reset curve is being used, then the
controlled setpoint becomes the maximum setpoint
(either SP MAX A1 or BOILR MAX). If a reset curve is
not being used, then DI closure for DHW has no effect.
• IGNORE causes the digital input to have no effect on
the Relay or Mod outputs.
