CONTROL MODE
The CPU-0600 is designed to be wall mounted or installed in a separate electrical enclosure. The unit should be
installed inside and protected from falling water and high humidity conditions. With all the covers in place, it is
designed to protect any individual from accidental electrical shock. It is not suitable for installation in hazardous
locations and should not be close to any electromagnetic elds.
• Identify the four mounting holes on the CPU-0600, mark on the wall the desired location of mounting
• Pre-drill, anchor and fasten four screws for mounting
• Hang CPU-0600 and fasten tight to desired locations
• Complete wiring connections in accordance with terminal locations
The programming instructions for the CPU-0600
are broken down into the ve control modes listed
below. When the control is rst plugged in you are
asked to select which control mode you would like
your CPU-0600 to operate in.
STAGING MODE (DEFAULT) – Programming for this
mode can be found on pages 6 through 14. This
mode is used when running boilers only. The boiler
congurations available in this mode are three
(3) modulating, On/Off boiler, two (2) stage On/
Off boiler, three (3) stage On/Off boiler and four
(4) On/Off boiler. Staging expandability is possible
with additional CPU-0600 controllers. In this mode
the control is able to control DHW and operate a
boiler, system, and DHW pump(s).
MIXING MODE – Programming for this mode can be found on pages 15 through 24. This mode is used when
running mixing pumps or valves. Mixing congurations include PMIp, Modulating, and Floating Action Valve. In
this mode the control can run up to four (4) on/ off boilers or three (3) mod boiler(s).
DIFFERENTIAL SETPOINT MODE – Programming for this mode can be found on pages 25 through 28. This mode
is used when running a differential setpoint. In differential mode, the control will also send a modulating signal
output based on how far the control is from the differential. This can be used to run a pump in modulating
applications for constant ow.
DUAL SETPOINT MODE – Programming for this mode can be found on pages 29 through 31. This mode is used
when one or two independent setpoints are needed. Each setpoint is set up individually and each has its own
thermistor input and relay outputs: Each setpoint has its own normally open and normally closed contacts
(which can be used for heating and/or cooling).
PUMP SEQUENCER MODE – Programming for this mode can be found on pages 32 through 34. This mode is used
to provide pump control for two pumps in a duty, standby situation. This control allows the system to sequence
and cycle pumps, override pumps and turn the pumps off when the outdoor temperature goes above a
certain value (WWSD)
In the event you select the wrong control mode, please cycle power to the
controller and it will display the control mode option screen.

2.4 GHz Wi-Fi network.
BOILER – Indicates the boiler temperature and
target. If there is a demand for heating the box will
be bordered with a red outline, and the staging
output(s) in the lower wiring chamber will be
closed.
SYSTEM – Indicates the system temperature and
target. When in boiler protection the box will have
a yellow outline.
OUTDOOR – The outdoor temperature will be
displayed. This option will also display if the control
is in WWSD (Warm Weather Shutdown).
DHW TANK – It will display the DHW temperature
and target. If there is a demand for DHW the zone
will be bordered with a red outline.
STAGES – Indicates how many boilers are being
utilized in your system setup. When a boiler is
activated by a heat demand the boiler will light up
in respect to their classication.
MODULATING STAGES- Indicates how many
modulating boilers are being utilized in your system
setup. When a modulating boiler is activated by a
heat demand the modulating boiler percentage
will start at the minimum mod percentage (%).
When there is no demand (off) the modulating
percentage (%) will displayed as 0%.
PUMPS/VALVE – When a pump/valve is activated
by a call you will see pump (P1) ,(P2), (P3) light up
in respect to their classication, their associated
contacts PUMP 1, PUMP 2, PUMP 3 can be found in
the lower wiring chamber will be closed.
DEMANDS - When the delegated demand is active
it will light up (DEMAND 1 - HD) or (DEMAND 2 –
DHW/SETPOINT) thus in turn the associated demand
in the upper wiring chamber will be closed.

The CPU-0600 allows for expandability for more boiler
staging between controllers. A maximum of four (4)
controllers can be utilized for a maximum of 16 boiler
stages. When using more than one CPU-0600, to allow
them to communicate wirelessly between each other,
they will need to follow a sequential order.
STAGE SEQUENCE SETUP – This setting will allow you to
select the stage sequence in your systems setup.
The rst sequence is labelled Primary and represents
sequence 1-4.
• Primary (Stages 1-4)
• Secondary (Stages 5-8) *CPU-0600 #2
• Secondary (Stages 9-12) *CPU-0600 #3
• Secondary (Stage 13-16) *CPU-0600 #4
CONTROL ID – If the Sequence was set to the Primary
then the number under Control ID will represent this
CPU-0600’s ID. If the CPU Sequence was set to any
sequence other than Primary, that CPU-0600’s Control
ID can be set to match the value of the Primary CPU-
0600 Control ID and the CPU-0600’s will then LINK
automatically. The CPU-0600’s will be LINKED when the
Sequence Link symbol appears on the top left of the
Main Screen for both controllers.

OUTDOOR RESET – This is used in the outdoor reset
design calculation. This option should be set to reect
your specic city or region.
(OFF/-40°F to 127°F)
BOILER SETPOINT – When a heat demand is present
and the control is not in WWSD, the control will target
this temperature for heating. This option will appear
when outdoor reset is set to off
(OFF/2°F to 210°F)
SYSTEM SETPOINT – : When a heat demand is present
and the control is not in WWSD, the control will target
this system temperature.
(20°F to 180°F)
MAX BOILER TEMP – This is used in the outdoor reset
design calculation, and also serves as the maximum
setting for the boiler. This is the maximum boiler
temperature for the coldest day.
(OFF/2°F to 210°F)
MIN BOILER TEMP: This is the minimum boiler
temperature. Set this to the temperature you would
like the boiler to be when the outdoor temperature
approaches WWSD.
(OFF/2°F to 210°F)
MAX SYSTEM TEMP: This is used to setup the maximum
temperature for your low temperature system on the
coldest day.
(20°F to 180°F)
MIN SYSTEMP TEMP: This is used to setup the lowest
temperature you would like in the low temperature
system. The setpoint will hit this when the outdoor
temperature approaches WWSD. (20°F to 180°F)

USE WEB OUTDOOR TEMP: This setting can be used for
outdoor temperature reading via the web instead
of installing an outdoor sensor. The control must be
connected to a Wi-Fi network and the user must set
the controller to a building via the Sensorlinx mobile
app for this setting to work.
(ON/OFF)
WARM WEATHER SHUTDOWN (WWSD): This setting is
used to set the temperature in which the CPU-0600
will go into WWSD. If the system rises above this
temperature, the system will be shut off. In WWSD the
boilers and all pumps will shut off.
(35°F to 120°F) Default: 70°F
WWSD TIME: This setting is used as a lag time for
WWSD. This will hold the control from entering WWSD
until this time has elapsed. The timer starts when the
outdoor temperature hits WWSD. This setting is useful
in the shoulder seasons when there are large outdoor
temperature swings.
