temperature sensor is two-wire, non-polarity specific. Re-
fer to
Figure 1-9
for wiring to the PMAC II Solo strip.

Table 1-2
shows how the 28 channels of the PMAC II
Solo are connected to the four UC12PG-R outputs.
1.5. Programming the UC12PG-R
Controller on the PMAC II
Solo Panel
With the sensor properly configured, all that remains to
set up the PMAC II Solo for humidity control is specifying
the minimum and maximum dewpoint setpoints ( Section
1.5.4.,
Entering/Changing Setpoints
), as well as the mini-
mum pulse percentage ( Section 1.5.4.3.,
Setting Pulse Per-
centages
).
1.5.1. Keypad
The PMAC II Solo keypad allows the user to navigate
through all the status and configuration screens and to ad-
just setpoints. The keypad has a four-line display and six
buttons, and can display up to 20 characters on each line.
To exit a screen without saving or to cancel an opera-
tion, press the button. The button allows you to se-
lect, enter information, or save changes into the controller.
The buttons move the cursor and allow
you to change configuration parameters.
1.5.2. How the Setpoints Work
The PMAC II Solo uses these setpoint values as shown
in the graph in
Figure 1-10
. When the dewpoint is at or be-
low the Minimum Dewpoint setpoint, the heaters will op-
erate at the percentage specified in the Minimum Pulse
Percentage setpoint. When the dewpoint is between the
minimum and maximum setpoint, the PMAC II Solo’s
pulse percentage varies between the Minimum Pulse Per-
centage and 100% (the higher the dewpoint, the higher the
pulse percentage). Finally, if the dewpoint meets or ex-
ceeds the Maximum Dewpoint setpoint, the heaters will
operate at 100%.
1.5.3. Logging Into the UC12PG-R
All day-to-day user functions, such as viewing alarms
and status screens are performed after being logged into the
system. Viewing and changing any configuration parame-
ters, such as setpoints, minimum pulse times, date, time, or
password, requires the user to enter a six-digit password.
