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.
