16.2. INSTALLATION OF A DOMESTIC WATER PRE-HEATING SYSTEM
A water heating loop option is also available to pre-heat domestic water using the energy produced by the Max Caddy
wood add-on. This water loop kit will be inserted between the wood combustion chamber and the heat exchangers.
When heating with wood, the heat from the add-on will pre-heat domestic water that will be stored in a feed tank before
entering your existing water heater. Removable panels are installed on both sides of the add-on for quick and easy
installation of the loop. A 24 volts solenoid valve must be installed at the inlet of the loop and must be connected to the
HOT H
0 terminal on the PC board; when the plenum temperature reaches 120°F, the valve opens to allow water
2
circulation. It closes when the temperature drops below 100°F to prevent overcooling the combustion chamber during
low firing rates. See section Erreur ! Source du renvoi introuvable. - Erreur ! Source du renvoi introuvable. for el
ectrical connection. Complete installation and operation instructions for the hot water loop kit are supplied with the kit.
17. CONFIGURATION AND OPERATING INSTRUCTIONS
17.1. CONTROLS SYSTEM
The Max Caddy add-on has a sophisticated electronic control. This system is more versatile. All connections are made
from the control panel. Terminal blocks are provided for all components and options.
Before you configure your system and learn how to operate it, make sure that your wall thermostat is wired correctly to
your add-on, that the temperature probe (RTD) is well installed in the hot air plenum and connected to the link board
and that your air distribution system is complete.
The add-on uses a touch screen, the latest technology in control devices. Options are controlled from this screen.
It is important to note that your add-on is equipped with two main electronic components: the link board and the touch
screen.
The link board is used more precisely for:
Connecting the hot air plenum's temperature probe (RTD type);
-
Connecting the wall thermostat;
-
-
Connecting complementary equipment;
The LCD touch screen is used to operate the system. More precisely for:
Choosing the combustion parameters;
-
Selecting the options used;
-
Show the temperature in the hot air plenum;
-
-
Selecting heating priority;
-
Selecting language and units displayed;
Viewing statistics;
-
Troubleshooting to detect problems with the appliance.

17.2. SYSTEM CONFIGURATION
Once the installation is complete and before using the unit, the add-on should be configured to activate all applicable
functions depending on options chosen. To do this, it is important to know which options are installed on your add-on.
17.3. TOUCH SCREEN
The LCD control is an electronic visual display as well as a touch screen that will light-up as you touch any location on
the display area. The main status page will then display different icons layout depending if the add-on is on or not.
