IntelliZone2 MasterStat System
Communicating with Humidity Control Thermostat
IntelliZone2 MasterStat Thermostat
User Information
This thermostat is a wall mounted, low-voltage thermostat
which maintains room temperature by controlling the operation
of a heating and air conditioning system. Batteries are not
required; temperature and mode settings are preserved with
the power off.
This communicating thermostat communicates
via a 4-wire Modbus protocol and will only operate with the
IntelliZone2 and Aurora AXB.
Thermostat Operation
NOTE: Outdoor temperature is only displayed if the outdoor
sensor is installed.
To select a MODE, press the screen button MODE, and then
press the desired operating mode.

to increase or decrease the heating temperature set point.
Depending on the selected mode one or both sets of the
up/down arrows will be selectable.
If a programmed schedule is active, the cancel button will
appear in the lower left hand corner of the screen when
temperature or mode selections are made. Select this button to
cancel any changes that were made.
Menu
Press the Menu button.
NOTE: The humidity function must be enabled by the installer
for it to display on this screen. If your system does not use a
humidifier this function may not be enabled.
Fan Operation
The thermostat can operate the fan in three ways:
AUTO (on only during heating and cooling
operation) (DEFAULT)
CONTINUOUS (always on)
INTERMITTENT (cycles fan)
From the Home screen or Menu Screen, press the Fan button.
Select the operation you desire as described above by pressing
the up and down arrows ▲▼.
Note: Continuous and Intermittent Fan selections are not
recommended when one zone is set for heating mode and
another zone is set for cooling mode. This is due to all zones
having a common return-air system. Air from the zones will mix
and lead to higher amount of run time.

Intermittent Fan
Temperature conditions can vary widely between the thermostat
location and the extremities of the space the thermostat serves.
This air stratification problem can be especially pronounced
during mild outdoor conditions when long periods elapse
between space conditioning demands from the thermostat. This
intermittent fan operation can also improve the performance of
air cleaning or special filtration systems that locate the cleaning
or filtration media at the return air side of the fan. If the FAN
hasn’t been on for an hour, the fan will start cycling based on the
times that the user enters in the set up of Intermittent Fan.
To turn intermittent fan on select FAN on the main screen and
then INTERMITTENT, then press OFF next to ON TIME. Press
the up and down arrows ▲▼ on the right hand side to adjust
the fan on time, this is the amount of time you want the fan to
be energized. Default is OFF. Ranges are OFF, or 5-20 minutes
in 5 minute increments. Press the box to the right of OFF TIME
this is the time the fan will be off. Press the up and down arrows
▲▼ on the right hand side to adjust the fan off time. Ranges
are 5-40 in 5 minute increments. Fan ON and OFF cycles will
continue until the fan has been energized by a call for heating or
cooling.
The zones can be selected by touching the upper right screen
text noting the zone. In this way you can cycle through all
the active zones to view and change their configurations. If
intermittent fan operation is desired in more than one zone then
all zones should use the same ON/OFF times otherwise the last
zone that was set will be followed for all zones.
Humidity
The humidity function must be enabled by the installer for this
screen to be visible. If your system does not use a humidifier
then this option may not be enabled. This allows adjustment
of Humidification and Dehumidification settings. Options are
Auto and Manual. Factory default setting for Dehumidification
is “Auto”. Humidification “Auto” is only available if an outdoor
sensor is installed. Manual humidity choices range from 15%
to 50% in 1% increments. Dehumidification choices range from
35% to 65% in 1% increments. For Variable Speed heat pumps,
when “Dehumidification” or “Both” is selected in the Installer
Setup, the Active Dehumidification feature will be enabled.
Active dehumidification (Variable Speed Heat Pumps
Only) will only activate during cooling operation and is based
upon the dehumidification set point of the thermostat being
at least 5% below the actual relative humidity. When in active
dehumidification the room temperature could be overcooled
1.5°F below set point. In this mode you may see increased
energy usage.
Zone
This screen shows the status of the IntelliZone2 system on
one screen. Displayed information includes zone size, priority,
normalized zone size, zone temperature set points, zone temp,
heating or cooling call, and damper open or closed.
From the ‘Zone’ screen, press next. This screen shows the
information the IntelliZone2 system is sending to the Aurora
controls and what the Aurora controls are responding.

AWL Status (If Installed)
Note: If AWL is installed, it is recommended that you enable
both the AWL Time Synchronization and Monitor AWL Status.
This screen displays the AWL firmware revision and provides
the current AWL communication status relating to an Aurora
WebLink (AWL) device. This screen is available whether an AWL
is installed on the system or not.
AWL Time Synchronization - When enabled the AWL will
synchronize the thermostat’s date and time with internet
time servers. This option by default is disabled. NOTE:
setting the proper time zone in the Symphony Portal
is necessary for correct operation.
Monitor AWL Status - When enabled, the thermostat will
monitor the AWL’s RS485, INTERNET, and SERVER
status. The thermostat will display “AWL Comm Err”
when the AWL is not communicating properly with the
Aurora Modbus Network, “AWL Internet Err” when the
AWL is unable to communicate to the symphony Servers.
This option by default is disabled.
CAUTION: To clean the thermostat display, lightly
dampen a clean non-abrasive cloth with water or
any non-abrasive household cleaner. To clean,
gently wipe the surface of the thermostat.
NOTE: Do not spray liquids directly on the
thermostat.

Fuel is selected for ‘Thermostat Type’ and a ‘W’ call is present
operation will be as follows:
1. The temperature will be controlled by the MasterStat while
other zones are ignored.
2. All zone dampers will open, Y1, Y2, G, W outputs shall
run for 60 seconds. After 60 seconds Y1 and Y2 will be
dropped and output only W and G (if Fan with Heat Option
is selected otherwise G will be dropped).
3. There will be a two minute minimum run time once Dual
Fuel operation has been entered, regardless if MasterStat
heat call has been satisfied.
4. Once the two minute minimum run time expires and the ‘W’
call is satisfied at the MasterStat then Dual Fuel operation
will be terminated. There will be no down staging.
5. Once Dual Fuel operation is terminated all zone dampers
will close.
6. There will be a 4 minute time delay once Dual Fuel
operation is terminated before compressor operation for
cooling or heating may begin.
