ACTii AC1112

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 measuring range (-40°C to +400°C)
  • ✔ Highest IP68 ingress protection class (silicone seal)
  • ✔ Durable stainless steel cover (Stainless Steel)
  • ✔ High-quality insulated copper control cable
  • ✔ Completely 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. 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 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 system requirements:

  • Installation in a tank (DHW/Buffer): Insert the metal sensor sleeve all the way into the dedicated well (measurement pocket). It is recommended to use thermal conductive paste for better readings.
  • Installation on pipes or outdoors: Apply the probe flat to the pipe, secure it with a clamp, and insulate it thermally, or mount it in a location sheltered from sun 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 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 anywhere.
  • Maintain the minimum bending radius (4 times the diameter).

Mechanical protection of the probe

Precautionary measures to prevent physical damage to the sensor.

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

⚠️ SAFETY WARNING

Never shorten or extend the cable without express recommendation from the manufacturer. Such modifications can permanently change the circuit resistance, which will distort temperature readings and disrupt the operation of the entire heat pump.
