1 Purpose and Functions
The sensor is designed for precise temperature measurement in heating and cooling systems. It ensures reliable operation and easy integration with heat pumps.
Main features:
- ✔ Wide probe measurement range (-40°C to +400°C)
- ✔ Top ingress protection rating IP68 (silicone seal)
- ✔ Durable stainless steel sheath
- ✔ High-quality insulated copper control cable
- ✔ Completely maintenance-free after proper installation
Operating principle:
The sensor continuously monitors the temperature of the environment or medium, and the heat pump control system automatically reads the values from it. Thanks to precise data, the heating system can optimally manage heat production, protecting the installation and ensuring maximum thermal comfort for users.

3 Installation and Configuration
General rules and connection:
Before starting any work, make sure that the heat pump power supply is completely disconnected. Route the cable to the control unit and plug the connector into the appropriate socket on the device's motherboard (according to the electrical diagram).
Probe placement:
The device allows for various installation options depending on system requirements:
- Installation in tank (DHW/Buffer): Insert the metal sensor sleeve until it stops into the dedicated thermowell (measurement pocket). Use of thermal conductive paste is recommended for better readings.
- Installation on pipes or outdoors: Place the probe flat against the pipe, secure with a tie, and thermally insulate, or install in a location shielded from sun and rain (as an external sensor).
Connection to the motherboard should always be performed by a qualified installer with appropriate certifications.
4 Connection Diagrams and Safety
To ensure maximum safety and device durability, strictly follow the guidelines regarding cable routing and mechanical handling of the sensor during installation.
Cable routing
Guidelines to prevent signal cable interference and damage.
- Avoid running the cable parallel to 230V/400V cables.
- Do not bend the cable at a right angle anywhere.
- Maintain the minimum bending radius (4 times the diameter).
Mechanical protection of the probe
Precautions to prevent physical damage to the sensor.
- Never pull the cable to extract the probe from the pocket.
- Tugging can damage the internal silicone seal.
- Damage results in sensor failure due to moisture ingress.
⚠ SAFETY NOTICE
Never shorten or extend the cable without the express recommendation of the device manufacturer. Such modifications can permanently change circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
