Thermostatic head REGULUS-system RTN81 remote 2 m cable SIRTN1

The thermostatic head REGULUS-system RTN81 remote 2 m cable SIRTN1 is a remote sensor thermostat head designed to control radiator or heating valve temperature using a separate sensor connected by a 2 m cable. It provides temperature regulation in situations where direct mounting of a conventional thermostatic head is impractical or where the sensing point must be positioned away from the valve for better measurement accuracy. The product is intended for integration with compatible valves and heating systems in residential and commercial installations.

Advantages

The REGULUS-system RTN81 remote model with a 2 m cable allows flexible placement of the temperature sensor independently from the actuator, enabling more accurate control in confined or awkward locations. Its compact actuator design simplifies integration with valve bodies where space is limited. The remote sensor cable reduces the risk of false readings caused by nearby heat sources or draughts, supporting stable room temperature control.

Suitable for

• Radiator and convector temperature control where direct head mounting is not possible
• Heating systems that require remote sensing for accurate temperature measurement
• Compact or recessed installations with limited actuator clearance
• Residential and small commercial buildings with zoned radiator control

Key specifications

• Device type: Remote thermostatic head with separate sensor
• Sensor cable length: 2 m
• Control function: Temperature regulation of radiator or heating valve
• Mounting: Separate sensor placement with compact actuator for valve connection
• Compatibility: Designed for use with compatible radiator/heating valves and systems

How to use

Install the actuator on the compatible radiator or heating valve according to the valve manufacturer’s instructions. Position the remote sensor at the desired sensing location, avoiding direct exposure to windows, radiators, doors, or other local heat sources that could skew readings. Route the 2 m cable without sharp bends and connect it to the actuator interface. Adjust the thermostat head or system controller to the required setpoint and verify stable operation by monitoring the valve movement and room temperature.

Usage recommendations

For reliable temperature control, position the remote sensor in a representative location of the room, at a typical occupancy height and away from direct sunlight or drafts. Ensure connections are secure and protected from mechanical stress. When integrating with a system controller or zoning setup, follow the system wiring and compatibility guidelines to maintain correct communication and control behavior.
