1 Intended Use 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-class IP68 protection (silicone seal)
- ✔ Durable Stainless Steel protective sleeve
- ✔ High-quality insulated copper control cable
- ✔ 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 power supply is completely disconnected. Route the cable to the control unit and plug it into the appropriate socket on the device's main board (according to the wiring diagram).
Probe placement:
The device allows for various installation options depending on the installation requirements:
- Installation in a tank (DHW/Buffer): Insert the sensor's metal sleeve fully into the dedicated thermowell (measurement pocket). The use of thermal paste is recommended for better readings.
- Installation on pipes or outdoors: Place the probe flat against the pipe, secure it with a cable tie, and insulate it thermally, or mount it in a place sheltered from the 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, strictly follow the rules regarding cable routing and mechanical handling of the sensor during installation.
Cable routing
Rules to prevent interference and signal cable damage.
- Avoid routing 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 probe protection
Precautions to prevent physical sensor damage.
- Never pull the cable to remove the probe from the pocket.
- Sudden pulling can damage the internal silicone seal.
- Damage leads to 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 the circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
