10.2. INSTALLATION OF AN AIR CONDITIONING UNIT
The Mini-Caddy furnace has been tested with an optional air conditioning unit. If this option is chosen, we recommend
an installation as per the graphic provided below.
A/C coil
This installation will provide the most efficient and safe operation of the air conditioning unit using the distribution
blower of the Mini-Caddy furnace during summer. In order to complete the installation of an air conditioning unit, the
main thermostat must be a "heat/cool" type. Furthermore, the desired distribution blower speed must be programmed
on the touch screen in the blower speed menu. (See Section 11.5 DISTRIBUTION BLOWER SPEED
CONFIGURATION)
It must be noted that upon thermostatic demand for cooling, the distribution blower will start immediately at the
programmed speed.
CONNECTIONS.
10.3. HEATPUMP INSTALLATION
It is possible to pair a heat pump to the Mini-Caddy. To determine the priority of operation of these two modes of
heating, you must go to Section 11.4.3 - AUXILIARY HEAT SOURCE PRIORITIZATION. For connection of the heat
pump to your furnace, see the wiring diagram.
Note: If a heat pump is connected to the Mini-Caddy, the electrical element must be installed to ensure an auxiliary
heat source. (PA08005(11.25kW))
For installation of air conditioning coil, refer to Section 10.2 - INSTALLATION OF AN AIR CONDITIONING UNIT.
11. CONFIGURATION AND OPERATING INSTRUCTIONS
11.1. CONTROLS SYSTEM
The Mini-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
the link board of 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.
