Thermostat Replacement And Maintenance - Lennox Harmony III Homeowner's Manual

Use up/down arrows to change the humidity setpoint (be-
tween 45 and 60%); press SAVE.
NOTE − If OFF was selected in installer settings for both hu-
midify and dehumidify, this message appears when HUMID-
ITY SETTING is pressed:
NOTE − If OFF was selected by the installer settings for DE-
HUMIDIFY but HUMIDIFY is on, the humidification menu
appears (this setpoint adjust has NO effect on dehumidifica-
tion):
- HUMIDITROL ADJUST is also available in the user settings.
The default setting is MAX dehumidification but can be
changed to MID or MIN. Use arrows to scroll to MID or MIN;
then press SAVE. Effectively, this adjustment allows more
(MAX) or less (MID, MIN) cooling beyond the cooling setpoint
while attempting to meet the relative humidity level setpoint.
Refer to installer and user settings sections of the Com-
fortSenset 7000 thermostat manual 506061−01 for more
information about Humiditrol Adjust.

OWNER REMINDER! Be sure the system installer has recorded
the zoning information in Table 1 on page 8 and has identified a
contact person and phone number in case of problems. If you
have the optional Humiditrol
cessory (EDA) along with the Humiditrol
installed, ask for a copy of those kit's installation and operation in-
structions.
Thermostat replacement
In the event a thermostat should fail and require replacement, be
aware that not all thermostats will work for all systems. Certain
types of thermostats, known as power-robbing thermostats, have
no C" (common) wire connection terminal; these can cause unin-
tended system operation and therefore must not be used. Call
your Lennox dealer to help you identify and install an appropriate
thermostat with a C" terminal.
Maintenance
Once your Lennox Harmony IIIt Zone Control System is properly
installed, no maintenance is required for the control panel's com-
ponents. Only standard heating and cooling equipment (HVAC)
maintenance is required.
If you experience problems turning the system on to either heat or
cool, the problem may simply be a programmed time delay,
which, in most cases, would expire within 5 to 20 minutes. Such
delays are normal and are built-in to assure proper equipment op-
eration.
