ACTii AC7512

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 protection class (silicone seal)
  • ✔ Durable stainless steel sheath
  • ✔ High-quality insulated copper control cable
  • ✔ Fully maintenance-free after correct 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 the 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 main board (according to the electrical 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 until it stops into the dedicated well (measuring pocket). It is recommended to use thermal paste for better readings.
  • Pipe or outdoor installation: Secure the probe flat against the pipe, fasten with a band and insulate thermally, or mount it in a location protected from sun and rain (as an outdoor sensor).

The connection to the main board 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 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 in parallel with 230V/400V cables.
  • Do not bend the cable at a right angle in any place.
  • Maintain the minimum bending radius (4 times the diameter).

Mechanical probe protection

Precautionary measures to prevent physical damage to the sensor.

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

⚠ SAFETY WARNING

Never shorten or extend the cable without explicit instruction from the device manufacturer. Such modifications can permanently change the circuit resistance, which will distort temperature readings and disrupt the entire heat pump's operation.
