2.3.3.3. DI 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
selections.
2. Use the
and
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, see Fig. 34
on page 16.
• ENABLE energizes all relays and MOD outputs to
100%. Use this option carefully.
• IGNORE causes the digital input to have no effect on
the Relay or Mod outputs.
2.3.3.4. SHOW RT
1. Press the
button to display the Show RT values.
2. Use the and
Default: YES
3. Press the
button to accept the value and return
to the Options menu.
Selecting YES shows the RT (run time) hours for each
relay on the home screen displays.
NOTE: Run times can be reset to zero for each
individual relay. You must do this for each
relay that you want to reset to zero. See
"2.3.4.3. RESET RT (run time hours)" on
page 29.
2.3.3.5. SYNC
(synchronize setpoint changes)
1. Press the
button to display the Sync values.
2. Use the and
Default: NO
3. Press the button to accept the value and return
to the Options menu.
Depending on the model, selecting YES causes all
setpoints for all relays and MODs to sync to any change
to:
• Relay 1 for models without MOD outputs
• MOD1 for models with MOD outputs
For example, assume the MOD1 setpoint is 110°F, MOD2
is 115°F, and Relay 1 is 120°F. With SYNC=YES, when
the MOD1 setpoint is adjusted to 112°F (increase 2°F),
then MOD2 and all other relay setpoints increase by 2°F.
Thus the MOD2 setpoint is now 117°F and the relay 1
setpoint is 122°F.
