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 measuring range (-40°C to +400°C)
- ✔ Highest IP68 ingress 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 ambient air 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 the heat pump power supply is completely disconnected. Route the cable to the control unit and plug the connector into the appropriate socket on the device motherboard (according to the wiring diagram).
Probe placement:
The device allows for various installation options depending on the needs of the installation:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve into the dedicated thermowell until it stops. Using thermal conductive paste is recommended for better readings.
- Installation on pipes or outdoors: Press the probe flat against the pipe, secure with a tie, and thermally insulate it, or mount it in a location sheltered 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 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 in parallel with 230V/400V lines.
- Do not bend the cable at a right angle anywhere.
- Maintain the minimum bending radius (4x the diameter).
Mechanical probe protection
Precautions to prevent physical damage to the sensor.
- Never pull the cable to extract the probe from a sleeve.
- Tugging can damage the internal silicone seal.
- Damage results in sensor failure due to moisture ingress.
⚠ SAFETY WARNING
Never shorten or extend the cable without the express recommendation of the device manufacturer. Such modifications can permanently change circuit resistance, which will falsify temperature readings and disrupt the operation of the entire heat pump.
