Outputs.

1.2.9. Subsequent Outputs

For the subsequent outputs (MOD 2, Relay 2, Relay 3,

etc. (if they are configured for Reset), the Offset

parameter displays on the Program menu as shown in

Fig. 35.

1.2.9.1 SETPOINT OFFSET (subsequent outputs only)

This value is the number of degrees plus (+) or minus (-)

that you want the temperature to be offset from the first

output’s setpoint. For example (as shown in Fig. 36), If

you want the MOD 2 setpoint to be 10° F (-12° C) less

than the MOD 1 setpoint, enter -10° F (-12° C).

1. From the menu, use the S and T buttons to

highlight OFFSET.

2. Press the X button to display the value.

3. Use the S and T buttons to increase/decrease the

desired temperature.

OFFSET Default: 0°F (-18° C)

OFFSET Range: -150° to 150° F (-101° to 66° C)

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

the next option.

1.2.9.2 Subsequent Outputs Programming

To complete the programming an output, perform the

procedures in “1.2.6. DIFFERENTIAL or THROTTLING

RANGE” through “1.2.8. SETBACK OFFSET

(if configured)” beginning on page 15

1.3. Exit Programming with Reset

When you finish programming all the outputs, press the

HOME button to leave programming mode and return to

the home screen.

This completes the programming procedure for

controllers that use Reset.
