IMMERGAS 3.024511 External Temperature Sensor
General warnings.
All products are protected with suitable transport packaging. The material must be stored in dry environments and protected against weathering. This instruction manual provides technical information for installing the kit. As for the other issues related to kit installation (e.g. safety in the work site, environment protection, injury prevention), it is necessary to comply with the provisions specified in the regulations in force and principles of good practice. Improper installation or assembly of the appliance and/or
components, accessories, kit and devices can cause unexpected problems to people, animals and objects. Read the instructions provided with the product carefully to ensure a proper installation. Installation and maintenance must be performed in compliance with the regulations in force, according to the manufacturer’s instructions and by authorised professionally qualified staff, intending staff with specific technical skills in the plant sector, as envisioned by the Law. The external probe connected to the electrical system of the cascade and zone regulator allows to automatically decrease or increase the max. flow temperature when the external temperature increases or decreases, in order to adjust the heat supplied to the system according to the change in external temperature.
OPERATION
Depending on the external temperature and the settings on the boiler, the latter defines the flow temperature according to the external temperature (see the regulator instruction book).
GENERAL FEATURES.
- The temperature probe is specifically designed for assembly in outdoor environments.
- Plastic container.
- Easy wall-mounting using a plug.
- Measurement range: -50°C ÷ 90°C
Important: it is mandatory to prepare a separate line to connect the external probe in accordance with the regulations in force regarding electric systems.
