Siemens RDE Series Thermostat, 230V Maximum Voltage, Wall Mount Type - RDE100.1 / S55770-T279

This thermostat is a room temperature controller designed for wall mounting in commercial and industrial installations. It provides Basic on–off temperature regulation via an LCD, accepts an external sensor input, and operates from standard mains supply for straightforward integration into building automation and HVAC control schemes.

Features and Benefits:

• 230V AC supply supports direct connection to the mains
• Two independent on–off outputs enable separate circuit control
• Single external input permits remote sensor operation
• LCD offers clear status and setpoint visibility
• IP30 enclosure rating suitable for protected indoor environments

Applications

• Suitable for temperature control in plant rooms and boiler rooms
• Ideal for integration with electrical distribution and control panels
• Used with fan‑coil units requiring simple on–off switching
• Can be used for room‑level control in office and commercial spaces

What supply voltages can it tolerate during installation?

The unit is designed to be powered from 230V AC and has a maximum supply voltage rating that aligns with typical mains limits.

How does it Interface with external sensors?

It accepts a single external input enabling connection to a remote temperature sensor for more representative room measurements.

What outputs are available for controlling heating or equipment?

Two on–off outputs are provided so separate devices or stages can be switched independently.

What environmental conditions limit its placement?

Operational ambient temperature is constrained between +5°C and +35°C and the IP30 enclosure requires installation in non‑exposed indoor locations.

Which approvals ensure conformity for industrial use?

The device complies with recognised regional standards and carries relevant conformity markings for use in its intended markets.
