1.4 A, 5-step transformer

For controlling ILTO 250, 260, 300 K and 400 K

Boosted ventilation control with a separate switch

(CO₂, clock, movement sensor, timer etc.)

For controlling ILTO 250, 260, 300 K and 400 K

Fireplace/boost switch with a timer

For controlling ILTO 250, 260, 300 K, 400 K and 650/850

The fireplace switch produces a brief overpressure and makes it easier to light a fireplace.

Thyristor regulator, surface/flush mounting model

ILVA carbon dioxide and temperature transmitter with a display

The carbon dioxide controller can be used to boost ventilation when carbon dioxide content rises

PC software:    Logging program, size 1,69mb 
                       UIP 4.0, size 2,2Mb  

ILVA humidity switch (hydrostat), IP 20 room mounting

The humidity switch can be used to boost ventilation in a washroom or other humid spaces in order to make them dry more effectively.

ILVA movement sensor

The movement sensor can be used to boost ventilation when the dwelling is occupied; at other times, ventilation can be at a lower speed.

ILVA week/day clock

The clock can be used to boost ventilation at regular intervals.
