Scroll Protection Module (SPM) —
There is one
SPM per compressor and it is responsible for controlling that
compressor. See Fig. 4. The device controls the compressor
contactor and the compressor crankcase heater. The SPM mod-
ule also monitors the compressor motor temperature, and cir-
cuit high pressure switch. The SPM responds to commands
from the MBB (main base board) and sends the MBB the
results of the channels it monitors via the LEN (Local
Equipment Network). See below for SPM board address infor-
mation. See Table 4 for SPM inputs and outputs.
