Display Description

Standard display (Parameters UP08, UP09, UP10)
• Active when no key has been pressed for 30 seconds.
• Contents may be chosen with parameters.
Loop display
• Active when changing set points.
• Large digits show input value if 1L 27 or 2L 27 = OFF. Small digits show set point.
If 1L 27 or 2L 27 = ON, only the setpoint is shown in the large digits.
• Vertical bars show analog output value. Arrows in position 1, 2 and/or 3 show active binary (digital) output stages
Display in OFF mode
• When the device is switched off, all enabled input values and the clock are displayed each for 4 seconds on the large
LCD digits in a continuous cycle while OFF is displayed in the small digits. To prevent this, make sure that in idle
mode no input values are shown on either small or large digits by setting UP09 and UP11 to something else than 1.
Override of secondary set point in cascade control
• If cascade control is active, with variable air volume (VAV) for example, the user can override the primary loop and
manually select the set point of the secondary loop-the loop is now changed to constant air volume (CAV). Typically
for tuning the VAV system. This feature may be disabled with UP02.
• While the secondary loop is displayed change the set point with UP/DOWN

. Override Cascade symbol appears.
• Press OPTION to move back to the temperature loop and cancel cascade override.
Power Failure
• All parameters and set points are automatically saved and do not need to be re-entered.
• Upon return of power: Set Parameter UP05 to keep the unit off, switch on, or operation mode before power failure.
• Clock and time schedule settings retained for 48 hours (after powered for at least 10 hours).
