The Relay Hysteresis will depend on how the relay is assigned. Units will either be in ppm for CO
°C/°F for temperature.
Use <UP> or <DOWN> to change the Relay Hysteresis within the limits as shown in the table.
Note that a high alarm resets when the measurement goes below (setpoint- hysteresis) and a low
alarm resets when the measurement goes above (setpoint + hysteresis). Note the value is somewhat
dependent on the setpoint (ie: if the CO

Use <UP> or <DOWN> to change the Relay Delay time within the limits. The delay time may be set
from 0 to 9 minutes in 1 minute increments to prevent false alarms. The default is 0 minutes (no
delay).
Press to advance to next menu item.
Use <UP> or <DOWN> to toggle the relay ON or OFF to test the relay operation. Press <MENU> to
reset to OFF and advance.

Use <UP> or <DOWN> to select the Setpoint Midpoint. Units are either C or F depending on the Temp
Units setting.
Note that the setpoint has + or - 10 steps from the midpoint.
For °C, the midpoint range is 18 to 25°C (resolution = 1°C, default = 21°C)
For °F, the midpoint range is 64 to 77°F (resolution = 1°F, default = 70°F)

Use <UP> or <DOWN> to set the Setpoint Action to either FWD (forward) or REV (reverse). FWD
means that as the setpoint value increases the output resistance increases. REV means that as the
setpoint value increases the output resistance decreases. Factory default is FWD.
Press to advance to next menu item
Use <UP> or <DOWN> to set the Setpoint Resolution to either 0.5° or 1.0° as required. The default
is 1.0° which means that the setpoint will increase or decrease by 1° for every button press. The
display will be 21.0, 22.0, 23.0, etc for example. For 0.5 resolution the display will be 21.0, 21.5, 22.0
for example. Factory default is 1.0. This applies to both °C and °F operation.
Press to advance to next menu item
The calibration reference screen allows user to set the calibration gas level used for calibrating the
sensor. Use <UP> and <DOWN> to adjust the ppm value of calibration gas. The minimum value is
400ppm, the maximum value is 2000ppm. Increment value is 50ppm for each step. Press <MENU>
to save and advance. If no calibration gas is available exposing the sensor to fresh outside can be
used and calibrate with 400PPM value. Another method is to determine the CO
a calibrated unit as a reference and adjust calibration setting to desired value.

This item is used to calibrate the CO
sensor. Consult the calibration instructions for the detailed procedure.
After applying the gas for several minutes, hold either the <UP> or <DOWN> key for 5 seconds to
start the gas calibration. The display will blink during the calibration time (approximately 10 seconds).
The display will change to "Calibrat / Done" when the calibration is complete. The display may indicate
"Calibrat / Fail" if the calibration fails.
Press to exit the menu and return to normal operation.
