ACTii AC8608

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

Operating principle:

The sensor continuously monitors the temperature of the environment or medium, and the heat pump control system automatically reads the values from it. With 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 the connector into the appropriate socket on the main board (according to the electrical diagram).

Probe placement:

The device allows for various installation options depending on system requirements:

  • Installation in a tank (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 installation: Place the probe flat against the pipe, secure with a tie, and thermally insulate, or mount in a location protected from sunlight and rain (as an outdoor sensor).

Connection to the main board should always be performed by a qualified installer with the appropriate authorizations.

4 Connection Diagrams and Safety

To ensure maximum safety and device longevity, strictly follow the rules regarding cable routing and mechanical handling of the sensor during installation.

Cable routing

Rules to prevent signal cable interference and damage.

  • Avoid routing the cable in parallel with 230V/400V wires.
  • Do not bend the cable at right angles anywhere.
  • Maintain the minimum bend radius (4x diameter).

Mechanical probe protection

Precautions to prevent physical damage to the sensor.

  • Never pull the cable to remove the probe from a pocket.
  • Jerking can damage the internal silicone seal.
  • Damage results in sensor failure due to moisture ingress.

⚠️ SAFETY NOTICE

Never shorten or extend the cable without the explicit 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.
