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 IP68 ingress protection rating (silicone seal)
- ✔ Durable Stainless Steel protective sheath
- ✔ 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 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 the installation requirements:
- Storage tank installation (DHW/Buffer): Insert the metal sensor sleeve all the way into the dedicated well (measuring pocket). It is recommended to use thermal conductive paste for better readings.
- Installation on pipes or outdoors: Place the probe flat against the pipe, secure it with a tie, and insulate it thermally, or install it in a place protected from sun and rain (as an outdoor 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 running the cable parallel to 230V/400V wires.
- 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.
- 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 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.
