Power: 24VAC ± 10%, 50 or 60Hz, 15VA max. power consumption.
Size: 5-1/16” [129mm] width x 5-11/16” [144mm] height x 1-1/2” [38mm] (minimum panel depth).
Housing: Rugged GE C2905HG Cycoloy plastic housing (complies with UL 94 V-O).
Environmental: 0-130°F (-17.8 to 54.4 °C), 10% to 95% non-condensing.
Protection: Surge & transient protection circuitry for the power and I/O. Optical isolation for
communications port.
Processor/Memory: High speed 16-bit Hitachi Processor with 1024kB RAM and 4096kB Flash Memory.
LED Indicators: Individual LEDs for digital outputs, power, run, error, transmit, and receive.
Compliance: UL916; FCC Part 15, Subpart B, Class A; ICES, Class A; EN55022, Class A;
IEC61000-6-1; RoHS complaint, WEEE Complaint; BTL listed
I/O Point Count: 5 digital outputs (on-board relays rated for 1A resistive at 24VAC).
6 universal inputs (IN-1 and IN-2 are jumper selectable for dry contact or 0-5VDC).
1 analog wall sensor port for non-communicating (Lstat) wall sensors.
1 digital wall sensor port for communicating (Rnet) wall sensors.
Communications: EIA-485 communications port using twisted pair. A two position DIP switch allows for manual
selection of desired protocol. Available protocols are BACnet MS/TP, Johnson Controls N2,
Modbus and LonWorks (requires Loc daughter card. Another 2 position DIP switch allows
for manual selection of desired baud rate. Available baud rates are 9600, 19.2k, 38.4k,
and 76.8k.
Addressing: 2 rotary switches are provided for setting the individual controller’s primary network address
(for more information on network addressing, see Addressing & Power Up).
Wall Sensor: The wall sensors provide room temperature sensing with digital display, local setpoint adjust,
local override, LED for alarm status and fault type indication, and heat pump reset. The wall
sensors require a 4 wire connection for communication or 5 wire connection for non-
communicating.
Mounting Hole Two mounting holes center line as below with 5-9/16” [141mm] height spacing.
Dimensions: Factory mounted.
