SIEMENS RDS120-B Smart Thermostat Instructions Overview

Summary of Contents

• Page 1: Smart thermostat Advanced cloud connected thermostat for light commercial and residential applications Bacnet over IP certified Controls conventional HVAC systems up to 3H/2C and heat pumps up to 4H/2C Easy-to-read, backlit, auto-dimming 3.5-inch, color, LCD touchscreen Intuitive remote user control using Apple iOS and Android mobile phone applications One-touch green leaf button to maximize energy efficiency Built-in volatile organic compounds (VOC) sensor enables ventilation strategies for optimum indoor air quality Built-in humidity sensor Built-in occupancy sensor enables occupancy control
• Page 2: Thermostat highlights include easy-to-understand tri-level air quality indication: “Good”, “Okay”, “Poor”. It features inputs for remote or averaging temperature and humidity sensors, along with a password-protected screen lock. The thermostat utilizes a PID algorithm for precise control and advanced energy-saving control with free cooling capability. There are two multifunctional inputs that are optional and configurable for various functions such as room temperature and operating mode switch. It has six relay outputs for conventional systems and heat pumps, as well as humidity or ventilation control. A guided setup wizard is included for ease of installation. The green leaf button engages occupants in maximizing system efficiency, indicating when setpoints are overridden. Mobile app features support iOS and Android smartphones, allowing for a full 7-day programmable schedule with three modes: Comfort, Economy, and Unoccupied. The app duplicates the thermostat HMI on a smartphone screen and includes user account management and monitoring of room conditions. Data security is ensured with the Siemens Cloud Computing Platform.
• Page 3: Power supply specifications include operating voltage and frequency. The operating voltage is 24 Vac with a frequency range of 48 to 63 Hz. Power consumption is a maximum of 9 VA with a current limit of 4A. Radio parameters operate within a frequency band of 2.4 to 2.4835 GHz with a maximum radio-frequency power of 18 dBm. The WLAN standard is IEEE 802.11b/g/n (HT20). Connections to multifunctional inputs include passive temperature sensors with specified cable lengths for different wire gauges. Supported sensor types include NTC, Ni, and Pt types. Active DC sensors operate within a range of 0 V to 10 V, with configurable min/max parameters. The default room temperature range is 32°F to 122°F, and the outdoor temperature range is -32°F to 176°F. Relay contact capacity is rated at 24 Vac with a minimum current of 0.02 A and a maximum of 1 A per output.
• Page 4: Setpoint range is 45°F to 95°F (7°C to 35°C). The built-in room temperature sensor has a temperature range of 32°F to 122°F. Accuracy at 77°F (25°C) is 0.9°F or 0.5°C. Display resolution is 1°F (0.5°C). The built-in room humidity sensor has a humidity range of 0% to 100%. Accuracy at 77°F (25°F) is 5% r.h. Wiring connections use screw terminals for solid or prepared stranded wires, with a maximum of 1 × 16 to 20 AWG. The product complies with various standards including BTL, FCC, and UL. Environmental compatibility includes RoHS compliance and materials composition. General dimensions are H 3.58” × W 3.58” × D 1.02”.
