Humidity Settings
Separate setpoints for humidifi cation and dehumidifi cation are
available in units of percent RH (relative humidity). The humidify
setpoint only is relevant if optional humidifi er equipment has
been installed and connected to the system (the 24 vac
“H” output – See the Field Wiring Installation Instructions).
The installer should clarify for the homeowner that priority
is given to cooling over dehumidifying, so the ability of the
system to satisfy the RH setpoint(s) depends on a variety of
conditions. For example if the cooling load causes the unit
to run at an intermediate speed or higher, the effectiveness
of dehumidifi cation is increased.
Humidifi cation can operate when the system is heating
or the fan is set to Manual (ON) with the compressor off.
Dehumidifi cation can operate only when the system is
cooling mode, the dehumidifi cation option is enabled, and
room temperature is close to the setpoint.
To set the humidity
setpoint(s), perform the following:
1. From the Main Screen, press the or key to select RH
at the bottom of the screen, then press the key to see
the Humidity screen. The current setpoints are displayed.
2. As indicated at the bottom of the screen, press the key
to enter the Humidity Settings screen.

3. Use the or key to select the RH setting to change,
then press the key to allow changes.
4. Use the or key to change the RH setting then press
the key to save the setting. The confi gurable ranges for
HUMIDIFY and DEHUMIDIFY are different, and changing
one may push the other so that a minimum of 5% is
maintained between the settings. The humidify setpoint
can be set in the range 30 to 45% in increments of 5%. The
dehumidify setpoint can be set in the range 35 to 70% in
increments of 5%. Press the key to save any changes
5. Press the key multiple times to return to the Main Screen.
Smart Recovery
When Smart Recovery is enabled, the system will start
changing the cooling or heating setpoint in advance of a
schedule change so that the room temperature is at or near
the setpoint of the subsequent schedule time block when that
time block begins. It only applies if the subsequent cooling
setpoint is lower or heating setpoint in higher. Also, if PROGRAM
SCHED USAGE is set to NON PROGRAMMABLE, this option
does not apply. To change the smart recovery option, perform
the following:
1. From the Main Screen, press the or key to select
MENU at the bottom of the screen, then press the key
to see the Main Menu.
2. Use the or key to select SETTINGS, then press the
key to enter the Settings menu.
3. Use the or key to select OPTIONS, then press the
key to enter the Options screen.
4. Use the or key to select the value under SMART
RECOVERY, then press the key to allow changing the
setting.
5. Use the or key to change the value between “OFF”
(the default) and “ON”, then press the key to save the
setting.
6. Press the key multiple times to return to the Main Screen.
Zone Control
The installer should provide to the homeowner(s) a document
or diagram which lists or shows (a) the rooms assigned to
each zone number, (b) the weighting assigned to each zone,
(c) the zone module number associated with each supply vent.
Current date and time must be set in the iQ thermostat/controller
since they will be transmitted to, and continually updated in
the local zone thermostats. The Security Lockout feature will
not prevent changing settings in local zone thermostats in an
iQ Zone system.
Temperature units (Fahrenheit or Celsius) can be changed
as follows: Locate the set of eight microswitches on the iQ
Zone main circuit board. Disconnect control power from the
circuit board. Set microswitch #6 up (on) for °F, down (off) for
°C. Reconnect control power.
It is recommended for the installer to instruct the homeowner(s)
on the following:
For zoning operation, Operating Mode (COOL, HEAT,
AUTO, E-HEAT, or OFF) must be selected from the iQ Drive
thermostat/controller as with non-zoning systems. However,
the temperature setpoints that will be used are entered and
stored at the local zone thermostats. With iQ Zone systems,
