KUR 5/G JOLA cooling ceiling controller

Description

The KUR 5/G cooling ceiling controller JOLA is a relay with an external mounting housing, which is made of a transparent cover. It contains a green LED indicator light and a red LED light to indicate the humidity inside the housing. For connection to the FTS/KO-1 film sensor.

Conductive relay in an upgrade housing with transparent cover, green LED for mains monitoring and red LED for moisture indication in the housing.

The KUR 5/G control ceiling is designed to measure the moisture between the printed conductors of the FTS/KO-1 film sensor and to switch the built-in output relay when the set sensitivity level is reached, allowing the external solenoid valve to be activated.

The cooling ceiling controller is in a protection circuit design: the potential-free switching contact is in quiescent current – in other words, the relay is energised when the sensor is dry.
