1 Purpose and Functions
The sensor is used 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 protective cover
- ✔ High-quality insulated copper control cable
- ✔ Fully maintenance-free after proper installation
Operating principle:
The sensor continuously monitors the temperature of the environment or medium, 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 insert the plug 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 installation needs:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve until it stops into the dedicated well (measurement pocket). The use of thermal conductive paste is recommended for better readings.
- Installation on pipes or externally: Attach the probe flat against the pipe, secure with a clamp and thermally insulate, or mount in a location sheltered from sun and rain (as an external 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 adhere to 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 at any point.
- Maintain the minimum bending radius (4 times the diameter).
Mechanical probe protection
Precautionary measures 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 results in sensor failure due to moisture ingress.
⚠ SAFETY WARNING
Never shorten or extend the cable without explicit instruction from the device manufacturer. Such modifications can permanently change the circuit resistance, which will distort temperature readings and disrupt the entire heat pump operation.
