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 class (silicone seal)
- ✔ Durable Stainless Steel casing
- ✔ High-quality insulated copper control cable
- ✔ Completely maintenance-free once correctly installed
Operating principle:
The sensor continuously monitors the ambient or medium temperature, 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 principles 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 mainboard (according to the wiring diagram).
Probe placement:
The device allows for various mounting options depending on installation needs:
- Tank mounting (DHW/Buffer): Insert the metal sensor sleeve until it stops into the dedicated well (measuring pocket). It is recommended to use thermal conductive paste for better readings.
- Pipe or outdoor mounting: Place the probe flat against the pipe, secure with a tie, and insulate thermally, or install in a place sheltered from sun and rain (as an outdoor sensor).
Connection to the mainboard should always be performed by a qualified installer with appropriate licenses.
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 routing the cable parallel to 230V/400V wires.
- Do not bend the cable at a right angle at any point.
- Maintain the minimum bending radius (4x diameter).
Mechanical probe protection
Precautions to prevent physical damage to the sensor.
- Never pull on the cable to remove the probe from the pocket.
- Jerking 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 the circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
