OPTIONS
A number of field-installed options are available on
SM Series of Heat Pumps. The following details the
purpose, function, and components of each
option.
Electric Heat
Internally-mounted supplemental electric heat is
available on select models of the SM series.
Electric heating elements can operate along with
reverse cycle heating as auxiliary heat or in lieu of
mechanical heating (refrigeration heating) as
emergency backup heat. The availability matrix,
including available nominal kW capacities are
shown in the table below.
Table 7 Availability Matrix
Smart Start Assist
The SM series is available with the Smart Start
Assist device as 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. The
Smart Start Assist device is depicted in Fig. 66.

Internally-mounted Electric Heat is only
available on top-blow vertical cabinets or
end-blow horizontal cabinets.
In cases where Electric Heat is not available in
a desired configuration but is needed, contact
your Bosch distributor or local sales rep. for the
available Duct Mounted Electric Heat Package.
NOTICE: Units with internal electric heat must
have two field power supplies.
