WIRING
CAUTION: Electrical shock hazard.
Can cause personal injury.
Be sure ventilator is correctly grounded. Confirm polarity of power line switched with safety (disconnect)
switch when cleaning or servicing unit.
IMPORTANT
The hot line (black) is the correct line to switch. See Fig. 19. To confirm correct polarity, use voltmeter or test lamp to
verify there is no power after the switch when the door is open. Check between that point and ground (on cabinet). This
process must be used because occasionally some dwellings are incorrectly wired.
CAUTION: Electrical hazard.
Can cause equipment damage.
Disconnect HRV/ERV from power source before connecting or disconnecting digital fan timer or other
device to HRV/ERV high-speed override terminals.
IMPORTANT
Do not connect external power sources to the highspeed override terminals.
Heat Recovery Ventilator (HRV) and Energy Recovery Ventilator (ERV) Connections
The connector is a three-prong, 120 Vac plug with ground. If further wiring is required, Honeywell recommends
that a licensed electrician make all electrical connections. It is very important that the unit be correctly grounded.
