Should you want to run the system at certain times and at certain speeds, all the options are available for you. With the provided touchscreen programmable controller, it is possible to boost the unit if required, for example during hot periods in the summer, or even reduce the speed if needed, perhaps when a baby is due to go to bed. Whatever the situation, Advance can be made to operate as needed. At the same time, automatic functions such as frost protection and summer bypass even have a choice of algorithms designed to suit different climates and lifestyles. The Vent-Axia Kinetic Advance SX Heat Recovery unit can also be connected via an application on your Apple or Android smartphone

Integral Humidity Sensor
The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The nighttime relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature

The outer enclosure is constructed of PVC with the inner body being constructed of EPP

The unit has 2 x low energy, high-efficiency EC/DC motors

You can change the spigot configuration electronically using the touchscreen controller

The condensate drain can be taken out through the back, side or bottom of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation

In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.
