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)
- ✔ Highest protection class IP68 (silicone seal)
- ✔ Durable stainless steel sheath
- ✔ High-quality insulated copper control cable
- ✔ Completely 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, 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 mainboard (according to the electrical diagram).
Probe placement:
The device allows for various mounting options depending on installation needs:
- Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve fully into the dedicated sheath (measurement pocket). It is recommended to use thermal paste for better readings.
- Installation on pipes or outdoors: Press the probe flat against the pipe, secure with a strap and insulate thermally, or mount in a location shielded from sun and rain (as an outdoor sensor).
Connection to the mainboard should always be performed by a qualified installer holding appropriate licenses.
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 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 in any location.
- 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.
- 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 the express recommendation of the device manufacturer. Such modifications can permanently change circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
