2.4.2

"TIME" menu

Date and time setting

Selecting between 12 and 24 hour time format

Note – Automatic switching between summer and winter times (DST) is not supported.
2.4.3

"INPUT" menu

 An option to allow / disallow the increased ventilation capacity function.
Binary input DI1 for connecting external voltage-free switches in bathrooms, toilets or kitchens.
-
An option to allow / disallow the function of automatic ventilation control according to the concentration of the quantity be ing

measured.
Analogue input IN1 for connecting an external sensor (sensor "S") with a 0-10V signal output which can monitor air quality, CO
-
concentration, relative humidity etc.
2.4.4

"SWITCH" menu (binary input DI1)

Setting ventilation capacity in a range of 10 – 100 % with input DI1 closed

Setting a function's start delay time in a range of 0 – 300 s (in 10 second steps)

Setting a function's run-down time in a range of 0 – 300 s (in 10 second steps)

If a button is used the start delay time must be set to "0 s" in order for the short press of the button to be accepted, and the run-down
time must be set to a non-zero value.
2.4.5

"SENSOR" menu (analogue input IN1)

Setting the ventilation curve in relation to the level of the 0-10V signal from an external sensor

This function allows suitably adjusting the unit's response (ventilation capacity) to a gradual increase in the concentration of the
quantity being measured, e.g. for economical or noise reasons.
The "inverse" setting of ventilation capacity response to the 0-10V control signal is also supported, i.e. the reverse direction of curve
A-B).
This function allows connecting also a sensor with a different output voltage range, e.g. 0-5V or 2-10V.
