1 Purpose and Functions
The sensor is used 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-class IP68 protection (silicone seal)
- ✔ Durable stainless steel cover
- ✔ 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 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 motherboard (according to the wiring diagram).
Probe placement:
The device allows for various installation options depending on installation needs:
- Tank installation (DHW/Buffer): Insert the sensor metal sleeve all the way into the dedicated thermowell (measurement pocket). Using thermal conductive paste is recommended for better readings.
- Pipe or external installation: Press the probe flat against the pipe, secure with a tie, and thermally insulate, or mount in a location shielded from sun and rain (as an external sensor).
The 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 for routing cables and handling the sensor mechanically during installation.
Cable routing
Rules to prevent interference and damage to the signal cable.
- Avoid running the cable in parallel with 230V/400V lines.
- Do not bend the cable at a right angle anywhere.
- 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 can damage the internal silicone seal.
- Damage results in sensor failure due to moisture ingress.
⚠ SAFETY NOTE
Never shorten or extend the cable without the express recommendation of the device manufacturer. Modifications of this type can permanently change the circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
