Specifications
User Interface
The user interface is a color display and has five push buttons.
Through the menu driven display, an operator can do the following.
• Add or change user passwords
• Change setpoints
• Set BACnet addressing
• Set up and commission the installation
• Configure any available options
Security
Separate passwords for users and controls technicians.
Display Type
• 128 × 128 pixels
• Active color LCD with LED back lighting
• 1.00 × 1.04 inches (25 × 26 mm)
Inputs and Outputs
All inputs and outputs are pre-programmed and application specific.
No field configuration is required for most installations. For details
on input and output connections see the section Application
Drawings on page 31.
Analog Inputs
Analog inputs represent BACnet analog input objects and are
configured for discharge air temperature, remote temperature
sensor, water temperature sensor, and fan status. Not all input
sensors are applicable or required for all models.
• Sensors are automatically detected
• Inputs accept industry-standard 10,000Ω, Type II
thermistor sensors
• Input overvoltage protection up to 24 volts AC, continuous
• 12-bit analog-to-digital conversion
• Short-circuit protected
• Loads up to 10 mA at 0-12 volts DC
• 8-bit PWM digital-to-analog conversion
IO-DAPPS
Relay Outputs
Relay outputs are configured to represent BACnet binary objects.
The outputs control ON/OFF valves, speeds for three-speed fans, fan
start circuits, or other equipment that requires an on or off input signal.
• All relay outputs are normally open, SPST, Form "A" relays
• 1 Ampere maximum per relay at 24 volts AC or DC for each output.
Maximum for all relay outputs is 3 amperes (72VA)
Connectors
• Screw terminal block mounted to backplate
• Wire size 14-22 AWG
Communications – BACnet™ MS/TP
• Integral peer-to-peer BACnet MS/TP network communications
• Network speeds from 9600 to 76,800 baud
• Front panel configurable device instance, MAC address, and baud
• Automatic baud detection

Regulatory
• UL 916 Energy Management Equipment
• FCC Class A, Part 15, Subpart B and complies with
Canadian ICES-003 Class B
• SASO PCP Registration KSA R-103263
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
• This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his
own expense.
