Electric Heat
Factory-installed internal electric heater packages
are available for all unit sizes. Refer to Table 10 for
heater package compatibility with specific SM
Split AH/AV units and any configuration
restrictions.
The circuit breakers for the heater package control
power for the heater elements, the blower motor,
and the control circuit for the unit. The circuit
breaker for the unit controls power for the
compressor. This allows the electric heaters to
continue to operate along with the blower motor in
the case of unit compressor and/or compressor
power supply failure. Refer to the SM Split Air
Handler with Electric Heat option wiring diagram
(Fig. 16).
Table 10 SM Split AH/AV Air Handler Heater Package Compatibility
Units supplied with internal electric heat
require two (2) separate power supplies:
one for the unit compressor and one for the
electric heater elements, blower motor, and
control circuit.
