Turning the System Off (All Models)
In order to shut off the system and prevent the Lennox
LPZ-2 Zone Control Panel from turning on your equipment,
you need to set ALL of your thermostats to the OFF mode.
Depending on your thermostats, this is done manually with a
slide switch on your thermostat’s sub-base or with a digital push
button. Consult the Owner’s Manual for your particular
thermostat.
If leaving the home for a long period of time, set the
thermostats to the Heat mode and adjust the set point to a
temperature that will prevent freezing in all areas of the home.
It is not recommended to turn off all thermostats for extended
periods in climates where freezing temperatures may occur.
Thermostat Replacement
Not all thermostats will work for all systems. If you need to
replace a thermostat, call the Lennox dealer that installed your
system. Certain types of thermostats, known as power
robbing thermostats, could cause unintended operation and
should never be used. You can tell if a thermostat is power
robbing by looking to see if it does not have a wire connection
terminal labeled C (common). Power robbing thermostats do
not have a C terminal. Only thermostats with a C terminal
should be installed.
Maintenance
Once your Lennox Zone Control System is properly installed,
there is no maintenance required to the control panel
components. Standard heating and cooling equipment
maintenance is required.
