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 rating IP68 (silicone seal)
- ✔ Durable stainless steel casing
- ✔ High-quality insulated copper control cable
- ✔ Fully maintenance-free after proper installation
Operating principle:
The sensor continuously monitors 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, make sure 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 motherboard (according to the electrical diagram).
Probe placement:
The device allows for various installation options depending on installation needs:
- Tank installation (DHW/Buffer): Insert the metal sensor sleeve all the way into the dedicated well (measuring pocket). It is recommended to use thermal paste for better readings.
- Pipe or outdoor installation: Attach the probe flat to the pipe, secure with a tie, and thermally insulate, or mount it in a place shielded from sun and rain (as an outdoor sensor).
Connection to the motherboard 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 follow the rules regarding cable routing and mechanical handling of the sensor during installation.
Cable routing
Rules to prevent signal cable interference and damage.
- Avoid routing the cable in parallel with 230V/400V cables.
- Do not bend the cable at a right angle anywhere.
- Observe the minimum bending radius (4x diameter).
Mechanical probe protection
Precautions to prevent physical sensor damage.
- Never pull the cable to remove the probe from the pocket.
- Pulling can damage the internal silicone seal.
- Damage results in sensor failure due to moisture ingress.
⚠ SAFETY NOTE
Never shorten or extend the cable without express recommendation from the device manufacturer. Such modifications can permanently change circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
