The V Output value controls the analog output voltage span if the PCB switch is set to VOLT. V Output
can be set to either 0-5 Vdc or 0-10 Vdc using <UP> or <DOWN>. This setting has no effect if the
PCB switch is set to mA. Factory default is 0-5 Vdc.
Press to advance to next menu item.
The Output value controls the analog output signal direction. Use <UP> or<DOWN> to change the
setting from Direct (4-20 mA, 0-5 Vdc or 0-10 Vdc) to Reverse (20-4 mA, 5-0 Vdc or 10-0 Vdc) if
reverse action is required. Factory default is Direct.
Press to advance to next menu item.
The Output Test value controls the analog output signal for testing purposes. Use <UP> or <DOWN>
to toggle the output signal to OFF (normal operation), MIN (minimum output) or MAX (maximum
output). The actual output signal will depend on the PCB switch position (mA or VOLT) and the V
Output setting (for voltage operation). Press <MENU> to set it back to OFF and advance. Factory
default is OFF.
Press to advance to next menu item.
The Temp Units setting is used to select °C or °F display of temperature. Use <UP> or <DOWN> to
select. The selection will also control available setpoint ranges if the setpoint option is installed.
Factory default is °C.
Press to advance to next menu item.
Display is used to control what information is displayed on the LCD. The selections depend on the
installed options. Use <UP> or <DOWN> to select either CO
None. Factory default is CO
or None.

The BackLite setting is used to control how the LCD backlight functions. Use <UP> or <DOWN> to
select either Auto, Off or On. Auto means the backlight only lights when a menu is accessed or when
the setpoint is activated (ie: when a key is pressed), Off means the backlight is always off and On
means it is always on. Factory default is Auto.
The T Offset value allows calibration of the temperature value displayed on the LCD. Units (°C/°F)
follow the Temp Units setting. Use <UP> or <DOWN> to add or subtract an offset from the
temperature value. The range is -5.0 to 5.0 °C or -9.0 to 9.0 °F in 0.1° increments. Factory default is
0.0 °C.
Press to advance to next menu item.
The Relay setting allows the relay alarm to be assigned to either CO
Temp Low as applicable. Use <UP> or <DOWN> to select. Factory default is CO
temperature sensor is not installed then the options will not be available.
Press to advance to next menu item.
The relay setpoint depends on the relay assignment set previously. Use <UP> or <DOWN> to change
the setting within the limits as shown in the table. Note that only the one previous selection will be
available. Note that a high alarm activates when the measurement exceeds the setpoint and a low
alarm activates when the measurement goes below the setpoint. Use <MENU> to save and advance.
