C2001011100 Compact HVAC Programmable Controller

Description

C2001011100

The C2001011100 is a compact programmable HVAC controller designed as an entry-level solution in Schneider Electric’s EcoStruxure Building Operation portfolio. As part of the company’s light commercial offering, it serves as a local control unit for small-scale heating, ventilation, and air conditioning systems, executing pre-configured or custom logic to maintain desired environmental conditions.

C2001011100

Its primary role is to process inputs from room thermostats, humidity sensors, and equipment status switches, then adjust outputs to valves, dampers, and fan coils—all while supporting basic scheduling and remote monitoring. For facility managers and contractors, the C2001011100 offers significant value through its plug-and-play design and intuitive programming interface, reducing installation time and training requirements. Whether controlling a single air handler in a retail space or coordinating multiple units in a small office complex, this controller integrates seamlessly with standard HVAC components, delivering reliable performance without unnecessary complexity.

Main features and advantages:

The C2001011100 distinguishes itself in light commercial HVAC controls with features tailored for simplicity and efficiency. Functionally, it supports up to 8 combined analog and digital inputs/outputs, providing enough flexibility for most small-scale applications—critical in settings like medical clinics where exam rooms require consistent temperatures but don’t need the advanced features of industrial controllers. Its simplified PID control algorithm maintains stable conditions with minimal tuning, making it accessible for technicians without specialized automation training.

Hardware design prioritizes space efficiency and durability. The ultra-compact enclosure (roughly half the size of larger Schneider controllers) fits easily in tight electrical boxes or equipment panels, while its robust construction withstands operating temperatures from 0°C to 50°C—suitable for installation in attic spaces or utility closets. A key advantage is its low power consumption (less than 3W), allowing it to operate from standard 24V HVAC transformers without overloading circuits.

Compatibility is a strong suit, with built-in support for BACnet MS/TP and Modbus RTU to connect with common thermostats and sensors, as well as integration with Schneider’s EcoStruxure Ready gateway for cloud monitoring. This versatility allows the C2001011100 to fit into both standalone systems and networked setups, providing a clear upgrade path as facilities expand.

Application areas:

In small to medium-sized commercial buildings, where efficient climate control directly impacts operational costs and occupant satisfaction, compact HVAC controllers play a vital role. From retail stores balancing customer comfort with energy savings to office suites managing variable occupancy patterns, these systems need to deliver reliable performance without the complexity of larger industrial solutions. The C2001011100 thrives in these environments, serving as a streamlined programmable controller that regulates heating, cooling, and ventilation equipment with the right balance of precision and simplicity—ideal for facilities where space is limited and installation speed matters.

Consider a 3-story office building with separate tenant spaces, each requiring independent temperature control. Here, the C2001011100 manages individual rooftop units, adjusting fan speeds and valve positions based on zone thermostats while communicating with a central dashboard for utility monitoring. In a chain of restaurants, it regulates walk-in coolers and dining area HVAC, ensuring food safety compliance and customer comfort without the need for specialized technical staff to operate. This controller is a workhorse in light commercial applications, providing the essential functionality needed to maintain optimal conditions while keeping energy usage in check.

Installation and maintenance:

Before installing the C2001011100, verify that the 24V power supply can deliver at least 300mA to accommodate the controller and all connected sensors. Use 18-gauge twisted-pair wire for analog signals to minimize noise, especially when routing near lighting fixtures or motors. Mount the controller away from direct sunlight and heat sources like furnace exhausts, maintaining at least 15mm clearance for cooling. Prior to powering up, confirm all input/output wiring matches the terminal diagram to prevent damage—pay special attention to polarity on analog sensors.

For maintenance, inspect wiring connections annually to prevent corrosion, particularly in humid environments like restaurants or indoor pools. Calibrate temperature inputs once per year using a reference thermometer, adjusting offsets through the programming software if needed. Check for firmware updates quarterly via the EcoStruxure platform, applying updates during off-hours to avoid temporary disruption. The C2001011100 includes status LEDs that simplify troubleshooting—steady green indicates normal operation, while flashing codes signal communication issues or sensor faults.
