T775M2030 Honeywell Temperature Controller

Overview

The Honeywell T775M2030 is a Series 2000 electronic stand-alone temperature controller designed for sophisticated commercial and agricultural HVAC applications. This versatile, multi-loop device provides precise on-off or analog (modulating) control for heating and cooling systems. It features two temperature sensor inputs, four SPDT relay outputs, and two analog outputs, allowing for complex staging and proportional control of various loads such as motors, dampers, and valves.

Features

• Easy-to-use graphical interface with a large backlit LCD display
• Intuitive menu-driven programming that reduces installation time
• Internal 7-day time clock scheduler for energy-saving night setback or shutdown
• Four SPDT relay outputs for multi-stage on/off control
• Two analog (modulating) outputs configurable for 0-10 Vdc, 2-10 Vdc, 4-20 mA, or Series 90
• Two temperature sensor inputs (one 1097 Ohms PTC sensor included)
• Configurable minimum off time to protect equipment from short-cycling
• Non-volatile memory to retain all programmed settings during power loss
• Modulating high or low limit control for equipment protection
