Configuration Parameters Default Value
UI19 Config (Universal Input Configuration

Default Value: Motion
Smart Recovery (Enable Smart Recovery)
Default Value: Off
Prop. Band (Proportional Band Setting)
Default Value: 3.0
• None: No function associated with input though input can be used for remote network
monitoring.
• COC/NH: Change over dry contact normally heat. Used to automatically change the Zone
Mode between heat/cool based on temperature of incoming air.
• COC/NC: Change over dry contact normally cool. Used to automatically change the Zone
Mode between heat/cool based on temperature of incoming air.
• COS: Change over sensor. Used to automatically change the Zone Mode between heat/
cool based on temperature of incoming air.
• Choices: None, COC/NH, COC/NC and COS.
• Motion: Occupancy status received from motion sensor.
• Schedule: Occupancy status configured in the Setup/Schedule menu. Refer to "Configu-
ration 7 / 9" on page 39.
• Mot. Occ: Occupied when scheduled occupied AND when motion is detected.
• Mot. Unoc: Occupied when scheduled occupied OR when motion is detected.
• Choices: Motion, Schedule, Mot. Occ., Mot. Unoc.
• Off: No smart recovery. The occupied schedule time is the time at which the occupancy
change will be applied, therefore the desired occupied temperature will not be attained
until some minutes after the scheduled time.
• On: Smart recovery active. The occupied schedule time is the time at which the desired
occupied temperature will be attained. The Room Controller automatically optimizes the
equipment start time. In any case, the latest a system will restart is ten (10) minutes prior
to the occupied period time.
• Smart recovery is automatically disabled if UI16 is configured to remote NSB.
• Choices: Off or On.
Adjusts proportional band used by Room Controller PI control loop.
Default value of 3 gives satisfactory operation in most normal installation cases.The use of a
superior proportional band different than the factory value is normally needed in applications
where Room Controller location is problematic and leads to unwanted cycling of the unit. A typi-
cal example is a wall-mounted Controller installed between return and supply air feeds and is
directly influenced by the supply air stream of unit.
Range: 3 to 10.
