Introduction_____________________________________
Any small DC refrigeration system using a Danfoss BD series of DC compressors
controlled by a “dial” or analog thermostat will benefit with an upgrade from the
standard thermostat to a Full Gauge electronic digital thermostat. Using the Full
Gauge digital thermostat allows complete control of both the set point and differential
of the thermostat operation. The set point is the temperature at which the system
will turn off, and the differential added to the set point will be the temperature at
which the system will turn on.
The Full Gauge thermostat has advanced features that add to the functionality of the
system. This document will describe the basic installation, wiring, and programming
of a Full Gauge controller to regulate a small refrigeration system.
The Danfoss DC compressor used in small refrigeration systems requires a control
module to run. The control module shown below has eight terminals for wiring
connections.
The essential connections for simple operation consist of:
1. DC Power: The DC power is to be provided by
adequately sized wires connected to the control
module terminal connections labeled large “+”
and “-”. The positive wire of the pair must be
protected at the source by an appropriate sized
circuit breaker or fuse. A table of fuse or circuit
breaker size is included at the end of this manual.
2. Thermostat: The thermostat wiring terminal
connections on the control module are labeled
“T” and “C”.
3. Fan: There should also be fan or water pump
wiring on the module terminal connections “F” and small “+”. This circuit has
a continuous current capacity of 1/2 amp and a peak capacity of 1 amp.
Optional wiring connections consist of:
1. LED: A diagnostic light emitting diode (LED) can be connected between module
terminal connections “D” and small “+”.
2. Battery voltage protection: A resistor (R2) may be connected between module
terminal connections “P” and “C”. The value of the resistor determines the

Full Gauge Digital Thermostat Kit Page 5 Rev 2.2 - March 2017
shut off voltage. A table of the resistor values for low battery protection is
included at the end of this manual.
3. Speed control: The compressor speed can be changed by adding a resistor (R1)
in series with the thermostat. If the system came with a resistor, the original
resistor value is usually the best choice and should be retained unless there is
a good reason to change it. Usually the manufacturer of the equipment has
determined the best compressor speed for the particular system to make it as
efficient as possible. Faster is not necessarily better, sometimes speeding up
the compressor results in less efficiency. A table of resistor values for various
compressor speeds is included at the end of this manual.
When upgrading from an analog thermostat, additional wires must be added to power
the Full Gauge thermostat from the compressor control module. The Full Gauge
thermostat power supply wire will attach to the existing power supply wires on the
large “+” and “-” terminals on the control module. Adapter terminals included in the
kit will allow the large “+” and “-” terminals to be shared. An inline fuse holder with
a 2 amp fuse will connect in series with the positive wire at the compressor module.
The power leads attach to Full Gauge thermostat connections 7 and 8. These
connections are polarity insensitive.
The thermostat wire connections on the control module will remain the same (“T” and
“C”), but the thermostat end of the wires will attach to the Full Gauge thermostat
connections 10 and 11.
The temperature-sensing probe will attach to the Full Gauge thermostat connections
3 and 4. If necessary, extend the probe wires with small gauge wire. It is best to
solder and heat shrink the wiring connections if additional length is required.
Preparation: Making Electrical Wiring Connections______
Please read the following section carefully before proceeding with the assembly and
installation of the kit.
To connect wiring to the Full Gauge digital thermostat connection terminals, strip
3/16” of the insulation from the wire ends of the multi-conductor cable before
inserting them into the appropriate wiring connection terminal. Avoid having any
loose strands of wiring that may contact other terminals and cause short circuits.
Wire ends that are attached to the wire electrical terminals will have 1/4” of insulation
stripped from the wire end before the terminal is crimped to the bare wire strands.
The wire electrical terminal also requires a second crimp to squeeze the barrel of the
terminal to the wire insulation, making a mechanical connection to relieve the strain
on the metal-to-metal crimped electrical connection.

Assembly: Electrical Wiring Connections______________
Connection on the Full Gauge Thermostat End
1. Locate the stainless steel thermostat mounting bracket (015-0000) and mount
the On/Off rocker switch (017-3101) and the Full Gauge digital thermostat
(015-0010) into the bracket. The “O” on the On/Off rocker switch should be
below the “l”. The switch will pop right in into the smaller hole of the bracket.
Remove the plastic bracket on the digital thermostat, insert the thermostat
through the larger hole from the front side of the bracket, and reattach the
plastic bracket to the thermostat on the back side of the bracket.

(Shown assembled with the On/Off rocker switch in the mounting bracket)
2. The temperature probe (015-0012, two white wires in black sheath on left side
or some probes are two black wires) attaches to the Full Gauge thermostat
connections 3 and 4.
3. The positive (+) 12 volt wire of the multi-conductor cable (241-0001, red)
connects to the bottom terminal of the rocker switch (017-3101) on the far left
through an insulated female spade terminal (290-0005). The top terminal of

Full Gauge Digital Thermostat Kit Page 7 Rev 2.2 - March 2017
the rocker switch attaches via another insulated female spade terminal (290-
0005) to a short length of wire (cut from red wire from the multi-conductor
cable) which then attaches to connection 8 on the Full Gauge thermostat (also
red in the photo). The other end of the positive, red wire of the multi-
conductor cable will connect to the Danfoss compressor control module large
“+” connection terminal in a later step.
4. The negative (-) 12 volt wire of the multi-conductor cable (241-0001, black)
attaches to the Full Gauge thermostat connection 7. The other end of the
negative, black wire from the multi-conductor cable will connect to the Danfoss
compressor control module “-” connection terminal in a later step.
5. The thermostat wires (in this case, 241-0001, white and green) connect to the
Full Gauge thermostat connections 10 (green) and 11 (white), and continue to
the Danfoss compressor control module “T” and “C” connection terminals.

Full Gauge Digital Thermostat Kit Page 8 Rev 2.2 - March 2017
Connection on the Danfoss Control Module End
The wires (241-0001, red and black) supplying power to the Full Gauge thermostat
use insulated female spade terminals (290-0001 and 290-0021) to connect to the
double male-female adapter terminals (290-0902) included in the kit and “piggyback”
with the Danfoss power supply cable (with a insulated female spade terminal) on the
large “+” and “-” terminals of the control module.
Danfoss Control Module Electrical Wiring Connections
(Also showing connections for condenser fan)
1. The Full Gauge negative (-) 12 volt DC supply wire (241-0001, black) connects
with a female spade terminal (290-0001) to the double male-female adapter
(290-0902) short terminal, and the Danfoss module 12 volt DC negative (-)
supply wire (aka condensing unit 12 volt DC negative supply wire) insulated
female spade terminal connects to the adapter long terminal. The orientation
of the insulated spade terminals attached to the wires must allow room for the
adapter terminal and the attached wire terminals to fit into the Danfoss control
module connector housing. Align the insulated female spade terminals so the
flat sides are facing each other. Insert the double male female adapter into
compressor module “-” connection terminal.

Full Gauge Digital Thermostat Kit Page 9 Rev 2.2 - March 2017
2. The Full Gauge positive (+) 12 volt DC supply wire (241-0001, red) connects
to a waterproof AGC inline fuse holder (017-2011) with an adhesive lined heat
shrink butt connector (290-0212) before continuing to the Danfoss control
module installation location. Heat the butt connector with a match, lighter, or
heat gun after making the electrical connections to activate the adhesive and
shrink the insulation around the wires, making a waterproof connection. If a
10 amp fuse is included with the fuse holder it should be discarded and
replaced with the 2 amp fuse (017-2000) included with the kit. The 2 amp
fuse will protect the wiring from damage due to possible accidental short
circuits in the Full Gauge supply wiring. The other end of the AGC inline fuse
holder connects to the double male-female adapter short terminal (2900902)
with an insulated female spade terminal (290-0021). The Danfoss module 12
volt DC positive (+) supply wire (aka condensing unit 12 volt DC positive
supply wire) insulated female spade terminal connects to the adapter long
terminal. The orientation of the insulated female spade terminals attached to
the wires must allow room for the adapter terminal and the attached wire
terminals to fit into the Danfoss module connector housing. Align the insulated
female spade terminals so the flat sides are facing each other, as described in
the previous step. Insert the double male-female adapter into compressor
module large “+” connection terminal.
3. The ends of the thermostat wires
(2410001, green and white) that are
attached to Full Gauge thermostat
connections 10 and 11 connect to
insulated female spade terminals (290-
0001), which then attach to the Danfoss
module connections “C” and “T” (green
and white, in the photos).
4. Gather together the wires attached to the
Danfoss control module and secure the
wires to the condensing unit base with
cable ties (400-0912) to prevent
accidental wiring disconnections from the
module due to inadvertent tugging on the
wires during the life of the installation.

Determining Thermostat Temperature Settings_________
The digital thermostat for refrigeration systems utilizing a roll bond evaporator can be
installed and programmed in either of two methods. In one method, the thermostat senses
and regulates the temperature of the evaporator, which has a low setting with a large rise in
temperature before the compressor restarts. The other method senses the box temperature
with a moderate setting and a small rise in temperature before the compressor restarts.
Evaporator Temperature Regulation Setting
In systems regulating the evaporator temperature, attach the probe as shown in the section
titled “Assembly: Temperature Probe Sensor Attachment”. Choose a large flat area away
from the evaporator tubes and near the exit of the suction line from the roll bond evaporator
to mount the thermostat probe.
For box shaped roll bond evaporators, the outside area around the evaporator will be the
refrigerator. An approximate setting to start with would be adjusting the setpoint (St1) to
around 8°F, with a differential (P1) of around 12°F. These are starting points; the actual
settings will have to be determined by the user. The settings are affected by the ratio
between the box volume and the evaporator surface area. Once the settings are adjusted,
it usually is not necessary to change them.
For flat or bent roll bond evaporators in freezer applications, the setpoint (St1) will probably
be near or below zero °F., and the differential (P1) will be around 8 to 10°F.
Box Temperature Regulation Setting
In systems regulating the box temperature, attach the probe in a position in the insulated
box near the middle and away from contact with the box walls or food placed in the box. The
digital thermostat programming will require a setpoint (St1) setting of around 36°F, with a
differential (P1) of about 2°F.
One disadvantage of sensing the box temperature to regulate the system is that when warm
food is added to the box, the system will continue running even when the evaporator is as
cold as possible, which is often the case if the evaporator is slightly undersized.
For systems with holding plate type evaporators, the box temperature must never be used
to control the system. Continuing to run a holding plate system long after the plates are
frozen causes extremely low suction pressures leading to oil migration and possible
compressor failure.
Holding plate systems should have the digital thermostat probe attached to the plate in a
manner and location that will sense the temperature of the solution in the plate as accurately
as possible. This should not be on the top surface of the plate, as there is space above the
plate solution to allow for expansion during freezing.
Usually the best place for thermostat probe placement is on the front or back surface, near
a lower corner of the plate. The probe may be attached as described in the photo sequence
in this manual, or the probe can be held against the backside of the plate with a piece of
foam used between the box wall and the back of the plate to press the probe against the
plate. It is important not to place the probe on the plate surface near where the evaporator

Full Gauge Digital Thermostat Kit Page 11 Rev 2.2 - March 2017
tubing is located within the plate. This can be observed visually when the plate first cools
from ambient temperature. The serpentine pattern of the tubing in the plate is visible in the
frost pattern as the plate begins to chill, usually within 20 minutes of starting the system.
The holding plate system needs to run until the plate liquid is completely frozen, and not
restart until the frozen plate completely thaws. The setpoint will need to be several degrees
below the freezing point, to assure that all the solution is frozen. For refrigerator plates, this
will be around 26°F., which requires a setpoint (St1) of around 22°F. For plates in freezer
applications, the solution usually freezes at about zero degrees F., meaning that the setpoint
(St1) will be about minus 4°F. The differential setting (P1) on both refrigerator and freezer
plate thermostats is usually about 8 to 10°F.
Optimizing Temperature Settings
These settings are a starting point; they may be optimized by careful observation of system
operation. Changing the values will change the run time and holdover time. At an optimum
setting, maximum holdover time will be achieved with the minimum required run time. The
values should be varied and records made of changes to determine the best settings for any
individual system. This will be time consuming and should be left to the system operator to
experiment with and determine the best settings.
Installation: Mounting the Thermostat Unit____________
When mounting the thermostat in a bulkhead, cut a rectangular hole that measures 4 1/4” x
1 3/4”. Feed the wiring through the hole from behind. Strip and connect the wires to the
Full Gauge digital thermostat and the On/Off rocker switch after their assembly into the
mounting plate. (The “O” on the On/Off rocker switch should be below the “I”.) Push the
wiring back through the hole until the mounting bracket is flush with the mounting surface,
and secure with four #4 x 1/2” round head screws (400-0381). Drill pilot holes for the screws
before driving them into the mounting surface.

Full Gauge Digital Thermostat Kit Page 12 Rev 2.2 - March 2017
Assembly: Temperature Probe Sensor Attachment_______
The thermostat must sense the temperature of what it is trying to regulate. Usually this will
be the evaporator or holding plate temperature. The oval end of the temperature probe
should be attached to the holding plate in an area that is out of the way of normal access to
the food in the box, yet in an area that most accurately senses the state of the plate, either
frozen or liquid. Holding plate systems need the condensing unit to run long enough to totally
freeze the liquid in the plate, and then stay off until the frozen liquid has completely thawed
before repeating the cycle.
One method of attaching the probe to the holding plate is shown in the photo sequence below.
The attachment method is the same for roll bond evaporators. Additional attachment tips
for roll bond evaporator applications are included at the end of the section.
1. Using scissors, cut three 2” long pieces of 2” wide foam
insulation tape (055-0041). Cut one of the pieces of
insulation as shown in photo on the right.
2. Clean the area on the surface of the plate where the probe is to attach. Use soap and
water or a suitable solvent such as rubbing alcohol or acetone. The plate surface must
be clean, warm, and dry for the insulation tape to adhere well.
3. Remove the backing from the adhesive and attach to the surface of the plate. Rub
well to assure maximum surface contact between the adhesive and the plate.
4. Lay the thermostat probe (015-0002) in the cut out of the
foam insulation attached to the plate.
5. Remove the backing from another piece of foam
insulation and attach over the probe on top of the first piece
of insulation.

Full Gauge Digital Thermostat Kit Page 13 Rev 2.2 - March 2017
6. Attach the third piece of foam in the same manner as the
second piece. Press the layers of foam tape together firmly
to assure good contact between the layers.
The same foam tape method of probe attachment can be used on the roll bond evaporator.
Mount the thermostat probe on a large flat area away from the evaporator tubes and near
the exit of the suction line on the roll bond evaporator.
