the minimum-off time delay. Four minutes must elapse after
the last furnace cycle before it can come on again. This built
in feature ensures that the furnace does not cycle too
frequently, which can reduce the life of your furnace.
Cooling Operation
1. To start cooling: Set your thermostat to the Cool mode.
Depending on the thermostat, this is accomplished by
either manually moving a switch to the Cool position or
digitally selecting Cool mode with a push button. Consult
your thermostat Owner’s Manual for details.
2. Adjust the thermostat set point to a temperature lower than
the displayed room temperature so that a Cool call is
initiated. Again, consult your thermostat Owner’s Manual
for details on how to do this properly.
When you have correctly initiated a Cooling call, the Lennox
LPZ-2 Zone Control Panel will start your cooling equipment.
If your air conditioning does not come on right away it may be
due to the minimum-off time delay. Four minutes must elapse
after the last air conditioner cycle before it can come on
again. This built-in feature ensures that the air conditioner
does not cycle too frequently, which can reduce the life of
your equipment.
Damper Operation
When the Lennox 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 purge cycle during which time the
dampers maintain their last position. After this purge all
dampers open.
Fan Operation
The Model LZP-2 Lennox Control Panel allows you to control
fan operation from any zone. Dampers in zones not calling for
fan will close. If continous fan operation is desired in all zones,
the fan must be turned on at the thermostat in both zones.
