NOTICE
The mitigation control board has a bank of DIP switches. Both DIP switches must be in the 1 or
on position. The room thermostat must control fossil fuel operation. W2 is applicable on only
multi-stage gas furnace models. Use the mitigation control A2L output instead of the G output for
Y81E, Z8ES, RL18,Y82E, Z8ET, Y91E, Z9ES, RG19, Y92E, and Z9ET gas furnace models.

This equipment uses an inverter drive that stores hazardous energy up to 5 min after power is
removed. Wait for more than 5 min before performing electrical work after power is removed.
Clearance
During installation, maintain the required clearance from walls and adjacent equipment. See Figure
HH8 heat pump 3. When installing multiple units, be careful to avoid intake of discharged air from adjacent units.
