16. CONFIGURATION AND OPERATING INSTRUCTIONS
16.1. CONTROLS SYSTEM
The Caddy 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 furnace, 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 furnace uses a touch screen, the latest technology in control devices. Blowers and power supplies are controlled
from this screen.
It is important to note that your furnace is equipped with three main electronic components: the link board, the power
board and the touch screen. The power board is already installed on the furnace.
The power board is used to supply current to the different electrical components, in particular:
-
Supply current to the different electronic boards;
-
Supply current to the distribution fan;
-
Supply current to the sequencers of the electrical unit (optional);
-
Supply current to the oil burner.
The link board is used more precisely for:
-
Connecting the hot air plenum’s temperature probe (RTD type);
-
Connecting the wall thermostat;
-
Connecting complementary equipments;
-
Connecting a heat pump.
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;
-
