Important Notes
Whilst programming, if no button is pressed for 10 seconds, the display starts flashing, and after 1 minute
returns to the main display without saving changes.
To increase scrolling speed, press and hold the ▲ or ▼ button for at least 5 seconds.
When pressing “PRG” for 3 seconds, the firmware revision code is displayed for 2 seconds.
When cleaning the controller panel, do not use ethanol, hydrocarbons, ammonia or their by-products.
Use neutral detergents and water.
In order to protect the unit’s components, minimum relay output on (3 or 7 minutes) and off (4 minutes)
times and minimum time (7 or 11 minutes) between activation of the same relay output are applied.
In case of digital inputs not configured, probes not fitted or configured, or St2 not enabled on the
controller the display shows ‘nO’.
