Siemens DDC R540-110 Control
The Siemens DDC R540-110 Control is a dedicated Terminal Equipment Controller (TEC) designed for localized management of fan coil units, unit ventilators, and heat pumps. This refurbished unit offers field-proven direct digital control, providing stable temperature regulation and energy management within a Siemens APOGEE or TALON network. Built with preprogrammed control algorithms, the R540-110 streamlines HVAC automation by reducing the need for custom programming. The module features individual wiring terminations for 24 VAC power and communication, along with a dedicated RJ-11 jack for local room sensor connection. For technicians handling legacy building automation systems, this digital control module ensures reliable sequences for heating, cooling, and fan operation. Its EEPROM data storage eliminates the need for battery backup, ensuring the HVAC controller retains its setpoint configuration and resumes operation immediately following a power interruption.
Key Benefits- Optimized for Terminal Equipment: Provides specialized DDC for pressure-dependent boxes and induction units.
- BMS Integration: Fully compatible with Siemens building management systems for centralized monitoring.
- Flexible Sequencing: Supports multiple hardware configurations including two-pipe and four-pipe fan coils.
- Non-Volatile Memory: EEPROM storage protects vital temperature setpoints and control parameters.
- Refurbished Reliability: Field-inspected and tested to meet essential performance standards for HVAC digital controls.
Is the Siemens R540-110 compatible with standard 24 VAC power?
Yes, this controller functions on 24 VAC 50/60 Hz and typically consumes approximately 3 VA of power, making it compatible with existing low-voltage HVAC circuits.
Can this module operate as a stand-alone controller?
The R540-110 is capable of stand-alone operation or can be networked via a communication bus to provide complex building automation data to a field panel.
What is required for the initial setup?
Technicians must select the appropriate preprogrammed application and assign a unique controller address. Calibration is usually not required, which minimizes commissioning time.
