CHAPTER 1 - OPERATING INFORMATION
The Main Menu (EZSetup, no code required) can be ac-
cessed from the Home Screen by touching the center
soft key . More information can be found in the In-
stallation manual of the INSTINCT units.
To shut down the unit, touch the soft key.
When touching the soft key, the unit shuts
down but is not isolated from power supply.
Therefore, live current is still present in the
unit. For your safety, disconnect electrical
power supply to the unit before servicing or
making any electrical connections to avoid
possible electric shock hazard. Failure to do
so can cause serious injury, or death.
• When shutting down using the soft key,
the appliance will not react to any heat de-
mand. However, the basic appliance protec-
tion functions (such as frost protection, etc.)
remain active.
• In addition, the arrow soft keys are no lon-
ger illuminated, and the soft key light-
ing is dimmed.

1.2. Installer Access Code
By pushing the installer button (PRESTIGE/HEATMAS
TER TC), or touching simultaneously the and
soft keys for 3 seconds (INSTINCT), the access code
window opens, where the installer can enter the spe-
cic code “054”. Subsequently, the installer can access
various setup screens and menus, allowing to dene a
large set of parameters and adapt the operation of the
CTRLMax to the system conguration.
To navigate on the screen, use the UP, DOWN, LEFT
and RIGHT keys, then the OK key to validate a selection.
To increase/decrease values, use the UP and DOWN or
LEFT and RIGHT keys, according to the situation and
validate with OK.
Entering the installer access code allows the in-
staller to make adjustments for 30 minutes. Af-
ter 30 minutes, the access code will need to be
entered again to make any adjustments.
If the end user misuses the installer code to ac-
cess installer-specific parameters and makes
changes that cause a system failure, any war-
ranty claim will be void.
