Accessories for Fan Coil Units (ECI)

IVAR.LAS, IVAR.LWS - Air-Water Sensor

We are still preparing products.

But you can look at other categories.

Sensors for controlling ECI series fan coil units – an air temperature sensor and a water temperature sensor, which provide the controller with input data for correct output control and switching between heating and cooling modes.

Frequently Asked Questions

What is the difference between the air sensor and the water sensor? The air sensor measures the temperature in the room or at the unit's intake, while the water sensor measures the temperature of the heat transfer fluid in the fan coil circuit; the controller evaluates both readings together.
Do I need both sensors at the same time? For most ECI controllers, yes – the combination of air and water temperature allows the controller to automatically detect heating or cooling mode and adjust output smoothly.
