3.3. Second Modulating Output and
Relays
For the second Modulating Output and the two Relays (if
they are configured for Reset), the Offset parameter
displays on the Program menu as shown in Fig. 75.
3.3.1. SETPOINT OFFSET
F
This value is the number of degrees plus (+) or minus (-)
that you want the temperature to be offset from the
MOD 1 setpoint. See Fig. 76. For example, If you want the
MOD 2 setpoint to be 10°F less than the MOD 1 setpoint,
enter -10°F.
1. From the menu, use the p and q buttons to highlight
OFFSET.
2. Press the u button to display the value.
3. Use the p and q buttons to increase/decrease the
desired temperature.
OFFSET Default: 0°F
OFFSET Range: -150°F to 150°F (-101°C to
66°C)
4. Press the u button to accept the value and display
the next option.
3.3.2. Second Modulating Output and
Relays Programming
To complete the programming of MOD 2 or a Relay,
perform the procedures in "3.2.5. THROTTLING RANGE
or DIFFERENTIAL" through "3.2.7. SETBACK OFFSET (if
80
°F
configured)" beginning on page 31.
3.4. Exit Programming with Reset
M24569
When you finish programming the Modulating outputs and
the Relays, press the HOME button to leave programming
mode and return to the home screen.
This completes the programming procedure for controllers
that use Reset.
