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 measuring range (-40°C to +400°C)
- ✔ Highest IP68 ingress protection class (silicone seal)
- ✔ Robust stainless steel housing (Stainless Steel)
- ✔ High-quality copper control cable with insulation
- ✔ Completely maintenance-free after proper installation
Operating principle:
The sensor continuously monitors the 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 rules and connection:
Before commencing any work, ensure that the heat pump's 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 placement:
The device allows for various installation options depending on the installation requirements:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve until it stops into the dedicated well (measuring pocket). It is recommended to use thermal conductive paste for a better reading.
- Installation on pipes or outdoors: Place the probe flat against the pipe, secure with a tie, and thermally insulate, or mount it in a place sheltered from the sun and rain (as an external sensor).
Connection to the main board should always be performed by a qualified installer holding the appropriate authorizations.
4 Connection Diagrams and Safety
To ensure maximum device safety and durability, strictly follow the rules regarding cable routing and mechanical handling of the sensor during installation.
Cable routing
Rules to prevent interference and damage to the signal cable.
- Avoid routing the cable in parallel with 230V/400V cables.
- Do not bend the cable at a right angle anywhere.
- Maintain the minimum bending radius (4 times the diameter).
Mechanical probe protection
Precautions to prevent physical damage to the sensor.
- Never pull the cable to remove the probe from the pocket.
- Jerking can damage the internal silicone seal.
- Damage leads to sensor failure due to moisture ingress.
⚠ SAFETY NOTE
Never shorten or extend the cable without express recommendation from the device manufacturer. Modifications of this type can permanently change circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
