The document describes controllers that are suitable for various applications. It can be used in applications where an over or under temperature fault condition could present a fire hazard or other hazard. It can also be used in hot-water systems with outflow temperatures above 110°C, heat generating plants with outflow temperatures up to 120°C, thermal transfer plants with organic transfer media, and oil-heated plants.
This document provides operating instructions for the PMA TB 40-1 temperature limiter. It details various applications where the device is suitable, such as heat generating plants and hot-water systems with specific temperature limits.
The manual describes the front interface features, including the BluePort panel and BlueControl software for setup without detailed study of the full instructions. It covers technical specifications for inputs (thermocouples, resistance thermometers, current/voltage), outputs (relays), power supply options, and environmental conditions.
