2.16 MAX BLOWER OPERATION
The
MAX
furnace has an advanced control that performs all of the safety and control functions.
There are two temperature sensors. One comes installed in the furnace and the AC/auxiliary
temperature sensor is installed after the A coil or auxiliary heating device. The control will
automatically handle two stage air conditioning and auxiliary heat such as electric plenum
heaters or heat pumps. The control will automatically modulate the blower for optimal airflow
regardless of the mode of operation. In heating mode the blower will modulate to maintain a
constant plenum temperature. In cooling mode the blower will modulate to attain the best
dehumidification performance even with two stage compressors. The control logic is detailed
below.
