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 ingress protection class IP68 (silicone seal)
- ✔ Durable stainless steel housing (Stainless Steel)
- ✔ 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 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 the heat pump power supply is completely disconnected. Route the cable to the control unit and plug into the appropriate terminal on the main board of the device (in accordance with the electrical diagram).
Probe placement:
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). Use thermal conductive paste for better reading.
- Installation on pipes or externally: Press the probe flat against the pipe, secure with a tie, and insulate thermally, or mount it in a place protected 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 guidelines 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 cables.
- Do not bend the cable at a right angle at any point.
- Maintain the minimum bending radius (4 times the diameter).
Mechanical protection of the probe
Precautions to prevent physical damage to the sensor.
- Never pull the cable to remove the probe from the pocket.
- Tugging may 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 falsify temperature readings and disrupt the entire heat pump operation.
