Comfort Alert Module
The Comfort Alert diagnostics module (CADM) is a
breakthrough innovation for troubleshooting heat pump
system failures. (Figure #55)
Figure # 55
B
y monitoring and analyzing data from the compressor
and the thermostat demand, the module can accurately
detect the cause of electrical and system related failures
without any sensors. A flashing LED indicator
communicates the ALERT code and guides the service
technician more quickly and accurately to the root cause
of a problem.
This module does not provide safety protection! The
Comfort Alert module is a monitoring device and
cannot shut down the compressor directly.
When an abnormal system condition occurs, the
Comfort Alert module displays the appropriate ALERT
and/or TRIP LED. The yellow ALERT LED will flash a
number of times consecutively, pause and then repeat
the process.
To identify a Flash Code number, count the number of
consecutive flashes. Every time the module powers up,
the last ALERT Flash Code that occurred prior to shut
down is displayed for one minute.
Energy Management System Relay
The factory installed Energy Management System Relay
can be used by individual commercial and/or residential
entities to monitor, measure and control their electrical
building load needs. This is accomplished by energizing
and de-energizing the relay coil which opens and closes
the relay contacts that are in series with the low voltage
output of the unit transformer and the input of the UPM
board.Energy

Smart Start Assist
SM series are available with the Smart Start Assist
device as either a factory installed option or a field
installed accessory. This device reduces starting (in-
rush) current for compressors by 45% to 65%. This
reduction in starting current can eliminate or greatly
reduce "light flickering" during compressor starts and
can reduce the required size of back-up transformers.
The adaptive technology of the device can also extend
compressor life by providing smoother, lower currents
starts and by protecting the compressor from transient
over voltage and under voltage after ramp up.
The Smart Start is designed for single phase scroll
compressors and can also optimize algorithms for high
pressure starts. SSA as showed in figure #56.
