The Siemens RDY2000BN is a powerful and versatile commercial room thermostat designed for light commercial HVAC systems. It is ideally suited for various applications such as schools, medical and financial offices, retail establishments, restaurants, and light manufacturing facilities. The thermostat communicates on BACnet, a widely used protocol in building automation systems.

Here are some key features of the Siemens RDY2000BN:

1. BTL listed MS/TP: The thermostat is BTL (BACnet Testing Laboratories) listed for compatibility with any BACnet system using MS/TP (Master-Slave/Token-Passing) communication.
2. Flexible control programs: The RDY2000BN has built-in control programs for both conventional and heat pump applications. It can control conventional systems with up to 3 stages of heating and 3 stages of cooling. For heat pumps, it can handle 1 or 2 compressors and up to 2 stages of auxiliary heat. It also includes an on-board temperature and humidity sensor.
3. Multiple configurable inputs and outputs: The thermostat offers multiple inputs and outputs that can be configured for advanced control strategies. It provides flexibility in setting up various control scenarios based on different conditions and sensors.
4. Set-up Wizard: The RDY2000BN features a Set-up Wizard that allows for rapid system configuration, making installation and commissioning easier.
5. Occupancy scheduling: The thermostat supports seven-day occupancy scheduling with options for 2-, 4-, or 6-event programming. This enables customized temperature settings based on occupancy patterns.
6. Backlit LCD touchscreen: The thermostat features a sleek design with a backlit 5-inch LCD touchscreen. The touchscreen interface provides easy and intuitive control and navigation.
7. Equipment protection and security: The thermostat includes interlocks and timers specifically designed for equipment protection. It also has a password-protected installer set-up menu to deter unauthorized changes.
8. Additional control capabilities: The RDY2000BN can control various additional equipment. It has a programmable fan for fresh air circulation when not in heating or cooling mode. It offers selectable lockout levels to minimize tampering with setpoints and schedules. The thermostat also supports programmable service reminders for humidifier pad, UV lamp, and air filter maintenance.

In terms of installation, the thermostat comes with a separable backplate, wiring terminals, and mounting holes configured to match most conduit box configurations. It can be mounted on drywall using the included screws and anchors. The thermostat secures to the mounting base with screws to deter theft and vandalism. It is designed for horizontal layout and is compatible with light commercial HVAC systems with 24 Vac control circuitry, including forced air, hydronic, and steam systems fired by gas, oil, or electricity.
