Split power is common in situations where a building has an emergency back up generator. In many cases, the back up generator does not have the capacity to power all the cooling and heating of the HVAC unit. In these cases, the HVAC units’ power is split into 2 parts. The first part is the power for the fan and the 24 V control power. This is the portion that is powered with and without the generator. In these cases, outside air but no cooling can be provided by the backup generator. The compressor power is the 2nd set of power. This is not powered by the backup generator.
iAIRE takes a customer-provided unit and breaks the wiring apart and installs the disconnect with this wiring for the 24V and fan power as a part of this modification. The customer will still need to provide a 2nd disconnect (or buy a 2nd disconnect from iAIRE) if they would like the 2nd disconnect provided.
