RS PRO Programmable Thermostat 240V AC, Temperature Range 5 to 35 °C, Max 50 °C Model 823-4958

RS PRO 823-4958 is a programmable wireless room thermostat designed for HVAC applications requiring precise temperature control and programmable scheduling over a 7-day period. This thermostat uses a radio frequency (RF) 868MHz communication between its transmitter and receiver, enabling flexible placement within 20 meters, supporting a neat separation of control center and wiring connections, simplifying installation in residential or commercial environments.

The backlit LCD display provides clear visibility of actual room temperature and set temperature. The user-friendly push-button controls allow simple adjustment, and the thermostat supports six comfort/setback periods daily, suitable for customized energy-saving schedules, including holiday periods, providing significant operational flexibility.

Operating with a contact supply voltage of 240V AC and an output voltage range of 24 to 240V AC, the thermostat is compatible with electric, gas, and oil heating or cooling systems. Its sensing element is an NTC thermistor providing temperature measurement from 0°C to 40°C with an accuracy of ±0.5°C.

Designed for indoor use, it operates reliably within an ambient temperature range of 0°C to 50°C and can be stored safely from -10°C to 60°C. The compact white unit includes pre-wired terminals for 2.5mm² cables, facilitating quick and secure installation.

This model conforms to FCC Part 15 and Europe standards, ensuring regulatory compliance. It requires 2x AAA alkaline batteries for its transmitter operation (batteries not included).
