Temperature Controller Lars 200 R wireless model AURLA02001009

The Temperature Controller Lars 200 R wireless model AURLA02001009 is a compact thermostat designed for remote regulation of heating and cooling systems. It supports setpoint adjustment, simple on/off control and wireless communication, making it suitable for installations where running control wiring is impractical. The device is intended for residential and light-commercial HVAC applications such as underfloor heating or radiator control and integrates basic control functions in a space-saving enclosure.

Advantages

The Lars 200 R wireless model offers straightforward temperature setpoint control with wireless connectivity that reduces installation complexity. Its compact design allows placement in a variety of indoor locations and the on/off control logic is compatible with typical zone valves and actuators. The controller provides a practical balance of basic control features and ease of installation for retrofit and new-build situations where simple temperature regulation is required.

Suitable for

• Residential heating zones (radiators, underfloor heating)
• Light-commercial spaces requiring simple temperature regulation
• Retrofit projects where running new cables is difficult
• Applications needing wireless room-level setpoint control

When it may not be suitable

This device implements on/off control and is designed for basic temperature regulation; it may not meet requirements for systems that need proportional, PID control or highly precise modulation. It is not intended as a full building automation controller and lacks advanced scheduling, multi-stage output, and extensive integration features required in complex HVAC systems.

Key specifications

• Function: Wireless room temperature controller with setpoint adjustment and on/off output
• Application: Heating and cooling zones, underfloor heating and radiator control
• Mounting: Compact indoor mounting suitable for wall or surface placement
• Control type: On/off relay output for direct connection to valves or actuators
• Communication: Wireless link for remote operation where cabling is impractical
• Target environments: Residential and light-commercial indoor spaces

How to use

Install the Lars 200 R in a representative room location away from direct heat sources, drafts and direct sunlight to ensure accurate ambient temperature measurement. Follow the manufacturer’s wiring instructions to connect the controller output to the compatible actuator or valve; pairing or configuring the wireless link should be performed according to the provided setup procedure. Set the desired temperature setpoint and verify the on/off control operates the heating or cooling actuator correctly. For consistent operation, use the controller together with compatible system components and verify batteries or power supply and wireless signal quality.

What to consider before purchase

• Verify compatibility of on/off output with your valve, actuator or boiler control interface
• Confirm that wireless range and signal conditions are adequate for your installation site
• Check required mounting location for representative temperature sensing (avoid heat sources and drafts)
• Ensure the device’s basic on/off control meets your system’s control precision requirements

Usage recommendations

For reliable performance, position the controller where it measures the average room temperature, periodically test the wireless connection and replace batteries or check power supply per the manufacturer’s guidance. Use the Lars 200 R for zone-based setpoint control in residential and small commercial systems where simple on/off regulation is sufficient.
