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.
Key features:
- ✔ Wide probe measuring range (-40°C to +400°C)
- ✔ Superior IP68 ingress protection rating (silicone seal)
- ✔ Durable Stainless Steel protective sheath
- ✔ High-quality insulated copper control cable
- ✔ Completely maintenance-free after proper installation
Operating principle:
The sensor continuously monitors ambient or medium temperature, 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 principles and connection:
Before commencing any work, ensure 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 main board (in accordance with the electrical diagram).
Probe positioning:
The device allows for various installation options depending on the installation requirements:
- Installation in a tank (DHW/Buffer): Insert the sensor metal sleeve into the dedicated thermowell (measuring pocket) until it stops. The use of thermal conductive paste is recommended for better readings.
- Installation on pipes or outdoors: Press the probe flat against the pipe, secure with a strap and thermally insulate, or install in a location sheltered from sun and rain (as an outdoor sensor).
Connection to the main board should always be performed by a qualified installer with appropriate certifications.
4 Connection Diagrams and Safety
To ensure maximum safety and durability of the device, the rules regarding cable routing and mechanical handling of the sensor during installation must be strictly observed.
Cable routing
Guidelines to prevent interference and damage to the signal cable.
- Avoid running the cable parallel to 230V/400V cables.
- Do not bend the cable at a right angle at any point.
- 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.
- Jerking can damage the internal silicone seal.
- Damage results in sensor failure due to moisture ingress.
⚠ SAFETY NOTE
Never shorten or extend the cable without the express recommendation of the device manufacturer. Such modifications can permanently change the circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
