OPERATION
11. CAN Bus Unit ID This parameter selection icon is grayed out whenever the Smart Touch is not plugged into a
Passport I/O board with the CAN bus daughterboard option. In other words, this parameter displays only when CAN-
bus network capability is available and the Smart Touch is plugged into a networked Passport I/O power and logic
board. This parameter does not display when the Smart Touch is plugged into a standard board. Each control on the
same CAN-bus network must be assigned a unique Unit ID (0 -255). For example, the control that is set to 5 will
respond to commands with a destination address of 5.
12. CAN Bus Group ID This parameter selection icon is grayed out whenever
the Smart Touch is not plugged into a Passport I/O board with the CAN bus
daughterboard option. In other words, this parameter displays only when
CAN-bus network capability is available and the Smart Touch is plugged into
a networked Passport I/O power and logic board. This parameter does not
display when the Smart Touch is plugged into a standard board. Assign the
address for the control's CAN-bus network group (0 - 255). This number
should be unique and different than any CAN-bus Unit ID. For example, all
controls that are set to 100 will respond to commands with a destination
address of 100 (in addition to responding to commands that target their
individual Unit IDs).
13. Voltmeter Calibration This parameter allows adjustment of the line voltage reading as measured by the Smart Touch.
This setting displays the voltage being read by the power and logic circuit board. It displays a live reading of the
voltage and can be manipulated by pressing the Up or Down icons. Calibrating this parameter provides a more
accurate voltage level when calculating low voltage. Use a reliable voltmeter as a reference when adjusting this
parameter.
14. Set Point Temperature Differential This parameter is the temperature
differential in Fahrenheit for all modes of operation: Automatic, Cool, or Heat.
Refer to "Modes of Operation" on page 8 for more information on how this
parameter affects these modes. By default, this parameter setting is 2°F
(1.1°C). It can be set to either 1°F (0.55°C) or 2°F (1.1°C). Setting this
parameter to 1°F (0.55°C) will result in the control maintaining the room
temperature closer to the desired set point. However, this may result in more
frequent shorter-duration cooling or heating cycles. In most cases, the
factory default of 2°F (1.1°C) is adequate for maintaining a comfortable
temperature variation around the desired set point. If you desire less
variation in temperature, set this parameter to 1°F (0.55°C).
15. Humidity Mode Min Temp This parameter is the minimum room temperature in Fahrenheit for which Moisture Mode
will run a cooling cycle to remove moisture from the air. If the room temperature is below this parameter setting,
Moisture Mode will run a heating cycle instead. By default, this parameter is set to 50°F (10°C), and it can be adjusted
between 40°F (4.4°C) to 75°F (23.9°C). Please refer to the description of "Moisture Mode" on page 9 for more
information on how Moisture Mode functions and utilizes this parameter.
16. Auto Fan Speed Temp Differential This setting sets the incremental
differential (with cumulative steps) between the ambient temperature and the
set point temperature at which the fan speed will increment to the next
speed. Note that there is 1°F hysteresis in the auto fan speed differential to
prevent the speed from changing if the room temperature changes by a
fractional degree causing speed fluctuations. Also General Settings
Reversed Fan Speeds in Heat, and Set Point Temperature Differential, both
have an effect on the operation of the auto fan speed.
