The Model LPZ-2 was designed to work with your single-
stage or self-staging heat/cool equipment (for example a
furnace and an air conditioner).
Basic Operation
Your Zone Control System will allow you to increase your
comfort by directing conditioned air to separate areas (zones)
based on each zone’s thermostat setting.
To operate this system, just set or program each zone’s
thermostat to your desired comfort set points. When there is a
heating or cooling call from any zone, the appropriate heating
or cooling equipment will be turned on. The dampers to zones
not requiring heating or cooling will close and the conditioned
air will be directed to the calling zone (s) until the thermostat
is satisfied.
Your zone control system is designed to direct conditioned air
only to the rooms served by that zone’s thermostat. However,
due to the open design of today’s homes, it may not be
possible to maintain drastic temperature differences between
zones. Closing interior doors is a good way to reduce the air
exchange between zones and increase the temperature
difference between them.
The following sections describe how to make Heating and
Cooling calls.
Heating Operation
To start heating:
1. Set your thermostat to the Heat mode. Depending on the
thermostat, this is accomplished by either manually moving
a switch to the Heat position or digitally selecting 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.
When you have correctly initiated a Heat call, the Lennox
LPZ-2 Zone Control Panel will start your heating equipment. If
the equipment does not come on right away it may be due to
