Setpoint Slide-Pot: When the temperature setpoint is active (see technician adjustments), moving the slide pot enough to change the
setpoint by one degree will display the setpoint on display units.
Override Button: When pressed, the override icon
will display on display units. A dry resistance of less than 15 ohms appears
across the override output (OVR1 to OVR2). Latching the Icon to show that the system is in override requires that a digital output on
your controller be used to connect terminal EXT-OVR to power supply ground.
