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 rating (silicone seal)
- ✔ Durable stainless steel housing
- ✔ 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 placement:
The device allows for various installation options depending on installation needs:
- Installation in a storage tank (DHW/Buffer): Insert the metal sensor sleeve all the way into the dedicated thermowell (measuring pocket). Using thermal conductive paste for better readings is recommended.
- Installation on pipes or externally: Attach the probe flat against the pipe, secure it with a clamp, and insulate thermally, 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 device durability, you must 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 in parallel with 230V/400V cables.
- Do not bend the cable at a right angle anywhere.
- Maintain the minimum bending radius (4x 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 the explicit recommendation of the device manufacturer. Such modifications can permanently change the circuit resistance, which will falsify temperature readings and disrupt the entire heat pump's operation.
