Configuring the DIII Board and MicroTech III Controller
1.
Navigate to the Enter Password screen if you have not already entered a password. If you have entered a password,
skip to step 3.
2.
Enter Password: 6363.
3.
Navigate to Commission Unit\D3 Set Up menu
4.
In the D3 Set-Up menu, set “ITouch Version” as desired
a.
“
USw/Spt
” – For use with Intelligent Touch Controller software versions 6.XX and iTouch Manager
software versions 2.XX. This setting allows the discharge air temperature setpoints to be adjusted by the
Intelligent Touch Controller/Manager; however the range for this setpoint is restricted to 60-90°F for the
Intelligent Touch Controller. On the iTouch Manager, the setpoint is restricted to the range set by the
MicroTech III unit controller.
b.
“
USw/oSpt
” – For use with Intelligent Touch Controller software versions 6.XX and iTouch Manager
software versions 2.XX. This setting prevents the discharge air temperature setpoint from being adjustable by
the Intelligent Touch Controller/Manager but allows, setpoints to be monitored (for applications where the
setpoint will be less than 60°F or greater than 90 °F).
c.
“
Std
” – For use with Intelligent Touch Controller software versions 4.XX and iTouch Manager software
versions 1.XX. This setting is allows for the discharge air temperature setpoints to be adjusted within the
range set by the MicroTech III controller.
5.
Set the ‘Low Speed =’, ‘Med Speed =’, and ‘High Speed =’ parameters to the percentages the unit’s supply fan will
receive when a Low, Med, or High speed command is sent from the Intelligent Touch Controller/Manager.
The speed
is set as a percentage of the supply fan’s maximum speed.
6.
Use “Temp Display=” to set a temperature for the Intelligent Touch Controller/Manager to display. This is the
temperature that will appear at the top of the side bar when a unit is selected on the iTouch Manager.
7.
Navigate to Commission\Cooling Setup
8.
Under the Cooling Setup menu, set Cooling Reset to None.
(The setpoint will not be sent to the controller from the
DIII network if Cooling Reset is set to Network because the DIII-NET Communication Gateway communicates to the
unit controller via MODBUS, rather than a COM module.)
9.
If the iTouch version is set to “USw/Spt,” verify that the “Min Clg Spt” and “Max Clg Spt” are set as desired (under
the Cooling Setup menu); as well as the “Min Htg Spt” and “Max Htg Stp” (under the Heating Setup menu). The
iTouch Manager will enforce these settings.
