ACTii AC9308

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 shield
  • ✔ High-quality insulated copper control cable
  • ✔ Fully maintenance-free after proper installation

Operating principle:

The sensor continuously monitors the 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 principles and connection:

Before commencing any work, ensure 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 (measurement pocket). Use thermal conductive paste for better readings is recommended.
  • Pipe or outdoor installation: Secure the probe flat against the pipe, fasten with a strap and thermally insulate, or install in a location protected 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

Guidelines 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 anywhere.
  • Maintain minimum bending radius (4x diameter).

Mechanical probe protection

Precautions to prevent physical damage to the sensor.

  • Never pull 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, falsifying temperature readings and disrupting the operation of the entire heat pump.
