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 measurement range (-40°C to +400°C)
- ✔ Highest tightness class IP68 (silicone seal)
- ✔ Durable stainless steel sheath
- ✔ High-quality copper control cable with insulation
- ✔ Completely maintenance-free after proper installation
Principle of operation:
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 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 (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 fully into the dedicated thermowell (measurement pocket). It is recommended to use thermal paste for better readings.
- Pipe or external installation: Apply the probe flat to the pipe, secure it with a clamp and insulate thermally, or mount it in a place sheltered from the sun and rain (as an external sensor).
The connection to the main board should always be performed by a qualified installer with appropriate licenses.
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 running the cable parallel to 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.
- 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 the express recommendation of the device manufacturer. Such modifications can permanently change the circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
