MAR7000 

1/2013, P/N 01757 Rev. B

Overview

The MAR7000 is a 

controller and sensors

 in a 

single, attractive package that creates a flexible 

solution to stand-alone control challenges or 

BACnet network challenges. Temperature, 

humidity, and motion sensing are standard. 

Flexible input and output configurations 

and built-in programming ensure that a 

variety of application needs can be met:

  Heat pump unit, with up to two 

compressor stages, and with op-

tional auxiliary heat, emergency 

heat, dehumidification, and/or 

fan status

  A/C, with up to two H/C stages, 

and with optional economizer, 

dehumidification, and/or fan 

status

Features

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 set-

points and other advanced features

  Schedules can easily be set uniquely by entire week (Mon.–Sun.), week-

days (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) pre-

vent disruption of operation and configuration

  Integral temperature, humidity, motion, and CO

2

 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
