Siemens RDH Series Thermostat, 8A Maximum Current, 250V AC Maximum Voltage - RDH100RF/SET / S55770-T378

This thermostat is a wall-mounted radio frequency controller designed to regulate environmental temperature within defined limits. It provides a clear LCD for status readout and connects to external systems via a single relay output, making it suitable for control panels and building automation where Compact radio-linked control is required.

Features and Benefits:

• Relay output rated for 8A protects connected actuators
• Operates from a 3V supply for low-voltage installations
• Supports switching up to 250V AC for mains-controlled loads
• IP20 enclosure suitable for internal, protected locations
• LCD display gives straightforward operational feedback
• Single-input handling simplifies integration with Basic sensors

Applications

• Suitable for room temperature control in commercial buildings
• Ideal for integration with HVAC control panels using RF links
• Used with electrically driven valves and actuators requiring relay switching
• Can be used for monitored zones where Compact wall mounting is needed

What environmental temperature range can it operate within?

It functions reliably between +5°C to +30°C, matching typical indoor climate control requirements.

How is the unit mounted and connected electrically?

The device is intended for wall mounting and provides one output relay and one input for straightforward wiring to control circuits.

What form factor and protection level should installers expect?

Expect a slim profile with a width of 120mm and length of 26.9mm, housed in an IP20‑rated enclosure for indoor use.
