update. The user will be notified once the download
is completed and installation begins. At this time the
phone can be removed from the Bluetooth range if nec-
essary (Note: if the phone is out of range, the user will
not know when the installation has completed or what
the existing status of the installation is).
Download the CoolCloud Phone Application and create
an account to get started. A Wi-Fi/Cellular connection
will be required for account setup.
Connecting Phone Application to Furnace
When in close proximity to the furnace, the phone
application will detect the Bluetooth Network being
broadcasted by the system. Once the Bluetooth net-
work is selected by the user, due to security reasons,
the user will be prompted for a 3 digit access code be-
fore system information can be displayed. The 3 digit
code will be displayed on the three seven segment
displays of the furnace control board. A sightglass is
located close to the control board that can be used to
see these digits. The user must enter the access code
into the phone application when prompted to do so in
order to gain access to system information. 3 failed
entry attempts will result in a new code being dis-
played on the control. If all 3 digits are not visible from
the sight glass, the user has two options to connect.
Option 1) Perform thermostat task as instructed by the
phone application to gain access. The following steps
will explain what this task involves.
•
Step 1
, ensure the thermostat is in an idol state (no
cool, heat or fan calls). To do this, set the thermostat
fan mode to Auto (not ON) and then remove any active
heat / cool calls. This task needs to be completed within
5 minutes of the process beginning.
•
Step 2
, provide any 24VAC call to the control from the
thermostat (cooling, heating or fan will work). This task
must occur within 8 minutes after the Step 1 is complete.
•
Step 3
, remove the call that was provided during Step
2. This task must be completed within 1 minute after the
call is provided during Step 2.
If the phone remains within Bluetooth range during the
three steps, the user will be notified when each step
has been completed and informed about what to do
next. If the user is not within Bluetooth range during
this process the phone application will still provide
instruction about what tasks to complete. After all 3
steps have successfully been completed, the user will
have access to system information once in range.
Option 2) Remove the furnace door, ensure the control
has power and then read the 3 digits. The code will
temporarily remain active after a power cycle so the
door can put back on before making the connection if
desirable. Note: power will be cycled to the control
board with this option. If it is not desirable to cycle
power to the unit for diagnostic purposes Option 1 may
be a better method to connect.
At power-up, the furnace control will display the unit
address (a two digit number) on the 2
nd
and 3
rd
characters
of the three seven segment displays. After the furnace
control has completed its’ internal start-up routine, the
furnace control will display the Status Menu.
The control board will display “Id L” while in idle
(stand-by) mode waiting for a call from the thermostat.
The furnace control is now ready to receive inputs
from the room thermostat.
The furnace control board will detect any compatible
communicating outdoor unit connected to it. Items that
appear in the main menu will vary accordingly. Exam-
ple, you will not see heat pump specific menus unless
a compatible heat pump is detected by the furnace
control.
Push Button Switches
Three push-button switches on the control board may
be used to navigate menus and select options. The three
switches are labeled Left, Center and Right. The center
switch is used to enter into the option menu and make
the selection, the left and right switches are used to
browse the main menu and option menus. When the
center switch is pressed in the main menu, the furnace
control will go to the option menu and display the
default or previously-selected option. Pressing the left
or right button will display the next available option.
When the next adjustable or selectable option is dis-
played, the furnace control will flash the option with
½ second ON and ½ second OFF indicating the option
has not yet been selected.
To select an option; press and release the center but-
ton to stop the current option from flashing. When the
option has stopped flashing, press the center button
again to select that option.
While navigating through options; if no switches are
pressed during a 30 second time period, the display
will time-out and return to the Status Menu. Simultane-
ously pressing & releasing any two switches will also
return the furnace control back to the Status Menu. If
the previously displayed option was not selected and a
timeout occurs, the displayed option will not be stored
in control memory as a selected option.
