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)
- ✔ Top-tier IP68 protection class (silicone seal)
- ✔ Durable stainless steel sheath
- ✔ High-quality insulated copper control cable
- ✔ Completely 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. 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 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 thermowell (measurement pocket). The use of heat-conducting paste is recommended for better readings.
- Installation on pipes or outdoors: Place the probe flat against the pipe, secure it with a cable tie, and provide thermal insulation, or install it in a location sheltered from sun and rain (as an external sensor).
The connection to the main board should always be performed by a qualified installer with appropriate certifications.
4 Connection Schematics and Safety
To ensure maximum safety and device longevity, strictly adhere to the guidelines 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 parallel to 230V/400V cables.
- Do not bend the cable at a sharp angle at any point.
- Maintain the minimum bending radius (4 times the diameter).
Mechanical probe protection
Precautions to prevent physical sensor damage.
- Never pull on the cable to remove the probe from the pocket.
- Pulling may 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 invalidate temperature readings and disrupt the operation of the entire heat pump.
