MAR7000

INTERFACE AND FUNCTION

• User-friendly English-language menus (no obscure numeric codes) on a 64 x 128 pixel, dot-matrix LCD display with 5 buttons for data selection and entry

• Built-in, factory-tested libraries of configurable application control sequences

• Integral energy management control with deadband heating and cooling setpoints and other advanced features

• Schedules can easily be set uniquely by entire week (Mon.–Sun.), weekdays (Mon.–Fri.), weekend (Sat.–Sun.), individual days, and/or holidays—or “learned” automatically via motion sensing

• Six On/Off and independent heating and cooling setpoint periods are available per day

• Three levels of password-protected access (user/operator/administrator) prevent disruption of operation and configuration

• Integral temperature, humidity, motion, and CO2 sensor options

• A 72-hour power (capacitor) backup and a real-time clock for network time synchronization or full stand-alone operation

BACNET STANDARDS

• Meets or exceeds BACnet AAC specifications in the ANSI/ASHRAE BACnet Standard 135-2008

INPUTS AND OUTPUTS

• Three or six analog inputs for use with external devices such as mixed air temperature, fan status, outside air, and remote CO2

• Analog inputs accept industry-standard 10K ohm thermistor sensors or dry contacts

• Inputs can be configured via a switch for 10K ohm pull-up resistors (for unpowered contacts or devices) or 0–12 VDC

• Input overvoltage protection (24 VAC, continuous)

• 12-bit analog-to-digital conversion on inputs

• Seven NO, SPST (Form “A”) relays carry 1 A max. per relay or 1.5 A per bank of 3 relays (relays 1–3 and 4–6) @ 24 VAC/VDC

CONNECTIONS

• Screw terminal blocks, wire size 14–22 AWG, for inputs, outputs, power, and BACnet network

• Integral peer-to-peer BACnet MS/TP LAN network communications on all devices (with configurable baud rate from 9600 to 76.8K baud)

• A four-pin EIA-485 data port on the underside of the case enables easy temporary computer connection to the BACnet network

• “E” versions add an RJ-45 jack
