CHAPTER 9 - CTRLMAX OPERATION
The CTRLMax Boiler Management System is designed
to be exible yet easy to use. CTRLMax monitors and
controls the INSTINCT to provide heat as eciently as
possible. CTRLMax includes many advanced features:
• Two central/space heating (CH) call inputs with
separate outdoor reset curves.
• Domestic Hot Water (DHW) call input with optional
priority in INSTINCT Solo units and DHW priority in
INSTINCT Combi units.
• EZ Setup feature allows the installer to quickly cus-
tomize CTRLMax for each installation.
• Optional cascade function (Solo models only), using
an optional wiring kit, allows up to six INSTINCT boil-
ers to operate together in a single heating system.
Refer to Fig. 10 on page 20 for more information.
• Modbus interface for integrating with building
management systems.
All CTRLMax features are easy to use through a graphi-
cal display where information is presented either graph-
ically or in plain English, so code charts are not required.
Fig. 34 below shows an CTRLMax display example of
the INSTINCT red for a domestic hot water demand.
9.1. CTRLMax Navigation
The CTRLMax navigation is performed through soft keys
that react to the touch and emit a short beep when tapped.
Exert a light and short touch (tap) on the soft
keys to activate their function. Holding the
touch too long will not generate any reaction
from the CTRLMax, unless it is a combination of
soft keys meant to be touched simultaneously
for a determined duration, as instructed in this
manual. The arrow keys can also be held longer
to increase or decrease values faster.
Navigation is performed through four arrow soft keys
,
, , with a center soft key (OK /Reset func-
tions) for making selections and entering information.
The installing contractor is provided with full access
to all available features after simultaneously touching
the
and soft keys for 3 seconds and entering a
code. Reference the INSTINCT CTRLMax Control Sup-
plement for Installer level functions
The Main Menu can be entered from the Home Screen
by touching the center soft key
.
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 elec-
trical power supply to the unit before servic-
ing 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 longer
illuminated, and the
soft key lighting is
dimmed.
