ACTii AC3808

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 measuring range of the probe (-40°C to +400°C)
  • ✔ Highest IP68 ingress protection rating (silicone seal)
  • ✔ Durable stainless steel housing
  • ✔ High-quality insulated copper control cable
  • ✔ Completely maintenance-free after proper installation

Operating principle:

The sensor continuously monitors 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 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 device motherboard (according to the electrical diagram).

Probe placement:

The device allows for various installation options depending on installation needs:

  • Installation in tank (DHW/Buffer): Insert the metal sensor sleeve fully into the dedicated sheath (measuring pocket). Using thermal conductive paste is recommended for better readings.
  • Installation on pipes or outdoors: Press the probe flat against the pipe, secure with a clamp and thermally insulate, or mount in a place shielded from sun and rain (as an outdoor sensor).

Connection to the motherboard should always be carried out by a qualified installer with appropriate certifications.

4 Connection Diagrams and Safety

To ensure maximum safety and durability of the device, 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 running the cable parallel to 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.
  • Pulling 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 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.
