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)
- ✔ Durable Stainless Steel shield
- ✔ High-quality insulated copper control cable
- ✔ Fully 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 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 motherboard (according to the electrical diagram).
Probe positioning:
The device allows for various installation options depending on the system requirements:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve fully into the dedicated immersion sleeve (measurement pocket). Using 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 insulate thermally, or mount in a place 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 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 damage to the signal cable.
- Avoid routing the cable parallel to 230V/400V lines.
- Do not bend the cable at a right angle anywhere.
- Maintain minimum bending radius (4 times the diameter).
Mechanical probe protection
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 NOTICE
Never shorten or extend the cable without express recommendation from the device manufacturer. Such modifications can permanently alter circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
