Damper
This installation will provide the most efficient and safe operation of the air conditioning unit using the distribution
blower of the Max 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. For the air conditioning damper wiring see Section 28 - LINK BOARD OPTIONS
CONNECTIONS.
The capacity and characteristics of the air conditioning unit that has been tested with the MAX Caddy are stated below.
The use of another brand with similar capacity and characteristics is adequate.

10.3. HEATPUMP INSTALLATION
It is possible to pair a heat pump to the Max 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 Section 28.7 - HEAT PUMP
Note: If a heat pump is connected to the Max Caddy, the electrical element must be installed to ensure an auxiliary
heat source. (PA08535 (20kW), PA08545 (25kW)
