Features Overview • 1
1 Overview
The PMAC II Solo is a solid state, anti-sweat heater
controller designed to dramatically reduce the cost of oper-
ating anti-sweat heaters on low-temperature door-type cas-
es found in most supermarkets.
Normally, anti-sweat heaters operate continuously with
no controls, even though 100% operation is required only
when in-store humidity levels are high. A PMAC II Solo
provides a means for pulsing power to the heaters based on
environmental conditions, so that heaters will be on for less
time during periods where the in-store dewpoint is low.
This reduces operating costs by limiting heater operation,
and increases heater life by limiting heat cycle fatigue since
the heaters are rarely turned off completely.
The PMAC II Solo performs all anti-sweat functions in-
dependently of a central Einstein, E2, or REFLECS con-
troller. The PMAC II Solo uses an Intellecs UC12PG-R
microcontroller mounted within the panel to control of all
anti-sweat heaters channels based on dewpoint (calculated
from relative humidity and temperature inputs) without
need for a central CPC site control system.
The UC12PG-R does not support multiple zone control.
All heaters are controlled by the same setpoint and dew-
point inputs.
1.1. Features
• Full Solid-State Control
• Quiet Operation
• Easily added to existing systems
• Controlled by the store environment (humidity and
temperature)
• Centrally-located panel
• Easy installation
1.2. Installation
This section of the manual covers wiring and installa-
tion for the PMAC II Solo.
1.2.1. Location and Wiring
1. Mount the PMAC II Solo in a central location
such as a motor or electrical room. The panel
should be in an area where there is plenty of
ventilation (e.g., not in a closet). Keep a 6-12
inch clearance on the top and bottom for
proper air flow. The room’s ambient tempera-
ture should always be below 100° F. See Fig-
ure 1-2 for dimensions.
Figure 1-1 - PMAC II Solo Detail
Figure 1-2 - PMAC II Solo Dimensions
WARNING: For proper cooling, the door
must be closed at times when unit is in opera-
tion.

2. Provide 120 VAC (15 amp circuit) to the
PMAC II Solo panel through a store circuit
breaker. See the layout design in Figure 1-3.
3. Provide power to the case heaters from the
store circuit breaker panel through the PMAC
II Solo panel terminal strip using #10-12
AWG wire, as shown in Figure 1-4.
Additional setup steps required are:
1. Wire the indoor air temperature sensor and
indoor relative humidity sensor to the termi-
nal strip at the bottom of the panel.
2. Program the high and low dewpoint setpoints
from the UC12PG-R controller’s front panel.
1.3. Sensor Mounting and Wiring
1.3.1. Mounting
The PMAC II Solo comes equipped with a wall-mount-
ed indoor temperature sensor (P/N 809-6580), and a wall-
mounted relative humidity sensor (P/N 203-5751).
1.3.1.1. Indoor Temperature Sensor
The indoor temperature sensor should be mounted in a
central location—within the zone to be measured—away
from doors, windows, vents, heaters, and outside walls that
could affect temperature readings. The sensor should be be-
tween four and six feet from the floor. In addition, the sen-
sor should not be mounted above other sensors that
generate heat during operation (such as relative humidity
sensors).
To mount the sensor, use a screwdriver to press in the
tab on the left side of the sensor enclosure, and lift the cover
off the enclosure. Use the two mounting holes on the back
panel to screw the sensor enclosure onto a flat surface (as
shown in Figure 1-5).
1.3.1.2. Indoor Relative Humidity Sensor
The indoor relative humidity (RH) sensor should be
mounted in a central location within the zone to be mea-
sured, away from doors, windows, vents, heaters, and out-
side walls that could affect humidity readings. The Sensor
should be between four and six feet from the floor. Note
that the RH sensor generates a small amount of heat; there-
fore, do not mount temperature sensors directly above RH
sensors.
Mount the RH sensor as follows:
Figure 1-3 - Typical Layout
Figure 1-4 - Typical Heater Wiring Layout
Figure 1-5 - Indoor Temperature Sensor Mounting

Sensor Mounting and Wiring Overview • 3
1. With a flat-head screwdriver, push down the
middle tab on the top of the sensor case and
pop the lid off to expose the circuit board.
2. Insert the flat-head screwdriver into the two
slots on either side of the top of the sensor
case and twist to separate the back plate from
the case.
3. Remove the knock-outs from the back plate
before mounting so wires may be threaded
through.
4. Mount the back plate to the wall using the
two open mounting holes on the top and bot-
tom of the plate.
5. Replace the cover on top of the back plate by
lining up the tabs, and snap the lid back into
place.
1.3.2. Wiring
The wall-mounted sensors must be connected to the ter-
minal strip at the bottom of the PMAC II Solo panel. The
necessary connections between this terminal strip and the
UC12PG-R controller are hard-wired by CPC during man-
ufacturing.
1.3.2.1. Wiring for RH Sensor
1.3.2.2. Sensor Cable Type
Wire the sensors to the PMAC II Solo terminal strip us-
ing Belden #8641 or equivalent for the temperature sensor,
and Belden #8771 or equivalent for the humidity sensor.
1.3.2.3. Wire Connections
Figure 1-9 shows how to connect the sensor cables to
the terminals on the sensor and the PMAC II Solo terminal
strip. Table 1-1 gives the wire colors for the Belden #8771
three-conductor cable and where they must be connected
on the sensor and the PMAC II Solo terminal strip. The
Figure 1-6 - Indoor RH Mounting Dimensions
NOTE: Before wiring connections are made
on the RH sensor, the output select switch
mustbe setto"VOLTS", andthe jumperset to
"5V" (five volts). See (Figure 1-7).

temperature sensor is two-wire, non-polarity specific. Re-
fer to Figure 1-9 for wiring to the PMAC II Solo strip.
1.4. UC12PG-R Output Mapping
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.

An RH Sensor Error alarm indicates that an RH Sensor
has exceeded alarm conditions. Check for a damaged sen-
sor. The humidity sensor is either shorted, open, or other-
wise not returning a valid signal that indicates a properly
working sensor. A wire connection may be broken or short-
ed, or the sensor itself may be faulty.
Temp Sensor Fail
A Temperature Sensor Failure alarm indicates that a
temperature sensor has exceeded alarm conditions. Check
for a damaged sensor. The temperature sensor is either
shorted, open, or otherwise not returning a valid signal that
indicates a properly working sensor. A wire connection
may be broken or shorted, or the sensor itself may be faulty.
PMAC High Temp
A PMAC High Temp alarm indicates the temperature
within the PMAC II Solo panel has risen above 165 degrees
Fahrenheit, indicating the panel may be approaching over-
heat shutdown. This usually means the panel’s exhaust fan
has failed or the door to the PMAC II Solo panel was left
open. If the temperature continues to rise in the panel, shut-
down will occur. Check for blocked vents, damaged fans,
or an open door on the PMAC II Solo.
Normal Power On Reset
This alarm indicates a power outage or other condition
that caused the UC12PG-R controller to reboot.
1.5.6. Percentage On Times
Percent On Time shows the average duty cycle (on
time) that the anti-sweat outputs have been operating at.
For example, if the outputs have operated at 0% for half an
hour and 100% for the next half hour, the Hour Percent On
Time would show 50%. Setting Zero On Time % to Active
manually resets all calculations.
1.5.6.1. Viewing the Percentage On Time
