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)
- ✔ Top-tier IP68 ingress protection rating (silicone seal)
- ✔ Durable Stainless Steel casing
- ✔ 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. 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, 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 electrical diagram).
Probe positioning:
The device allows for various installation options depending on system requirements:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve fully into the dedicated immersion sleeve (measurement pocket). It is recommended to use thermal paste for better readings.
- Installation on pipes or outdoors: Press the probe flat against the pipe, secure with a strap and thermally insulate, or mount 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 device durability, 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 running the cable parallel to 230V/400V wires.
- 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 explicit instruction from the device manufacturer. Such modifications can permanently change the circuit resistance, which will falsify temperature readings and disrupt the entire heat pump operation.
