generally be identified by the presence of an additional mode
category of Emergency Heat. A call for Emergency Heat will
use a source of heating apart from your Heat Pump. To
operate Emergency Heat you must do the following:
1. Set your thermostat to Emergency Heat. Depending on the
thermostat, this is accomplished by either manually moving
a switch to the Emergency Heat position or digitally
selecting Emergency Heat mode with a push button.
Consult your thermostat Owner's Manual for details.
2. Adjust the thermostat set point to a temperature higher than
the displayed room temperature so that a Heat call is
initiated. Again, consult your thermostat Owner's Manual
for details on how to do this properly.
Once Zone 1 has successfully made an Emergency Heat call,
the control panel will remain in the Emergency Heat mode
until the Zone 1 thermostat calls for standard Heat Pump
Operation or it makes a Cooling call. While your Control Panel
is in the Emergency Heat mode, Zones 2 and/or 3 can not call
for cooling.
Note: Emergency Heat is generally much more expensive
to operate than the Heat Pump. Use only when necessary.
Your equipment may not include Emergency Heat.

Damper Operation (All Models)

When the Aprilaire Zone Control Panel receives a call and
turns on the appropriate equipment, it also automatically
closes the dampers that serve the non-calling zones and
opens those in the calling zones. When all calls are satisfied,
the Control Panel initiates a 1 minute purge cycle during which
time the dampers maintain their last position. After this purge
all dampers open.
