Overview
Your heating device is protected by a safety code against nonauthorised
use. The PIN code (Personal Identity Number) is a
customisable 4 numbers code. When enabled, it prevents access to the
following settings:
- Selecting the Comfort mode : The access to the Comfort mode is
forbidden, only the Auto, Eco and Frost protection modes are available.
- Minimum and maximum Limits of the setting temperature range (the
Comfort temperature modification is forbidden out of the authorised
setting range).
- Programming mode.
- Open window detection settings.
- Setting the Eco mode temperature lowering-level.
- Setting the Frost protection temperature.
3 important steps are needed for the first use of the PIN code lock:
1 - PIN code initialisation, enter the preset PIN code (0000) to access to
the feature.
2 - Activation of the PIN Code to lock settings which will be protected
by the PIN code.
