ABOUT ACORN CONTROLS
Past and Present
Acorn Engineering
Company has been
manufacturing valves
for plumbing xtures in our
North American manufacturing
facilities since the introduction of
Auto-Cloz, Single-Trol and Safti-Trol
valves in 1969.
Throughout the next ve decades, Acorn
continued to introduce valves like the
Penal-Trol line for institutional applica-
tions; Master-Trol, an electronic water
management system that allows facilities
to precisely control and monitor water
usage; and several generations of
Air-Control and Flood-Trol valves. In 2013,
Acorn introduced the Acorn Controls
product line, a new generation of thermo-
static mixing valves that manage single
xtures, multiple xtures, or whole
building water systems. Acorn is proud
to continue its track record of providing
valves while updating the product line
with state of-the-art technology that keeps
people safe.
Acorn Engineering Company
was founded in 1954
by Earl L. Morris, who
wanted to manufacture the type
of specied products he most enjoyed
selling at his manufacturer’s representative
company, the Earl L. Morris Company. As
Acorn grew, a number of companies and
partnerships were acquired, and in 2012, a
new parent company was formed—Morris
Group International (MGI).
Today, Morris Group International is
made up of 25 divisions and partnerships
manufacturing products. Our products
come out of our manufacturing facilities in
North America ready to meet the needs of
any construction or building project.
With over 75 patents and thousands of
products, Morris Group International has
over 1,600 employees and over 2 million
square feet of ofce, warehouse and
manufacturing space worldwide.

BASyC™ systems with Recirculation Pump by Others
If your BASyC™ system as provided by Acorn does not include the recirculation pump, it should be provided
by others. Relay pump control may or may not, be included with BASyC™ regardless of whether Acorn
supplies the pump.
Inlet Temperature Sensor
If equipped with the inlet temperature sensors option, your BASyC™ system includes CW and HW inlet
sensors. Data from these sensors will be stored by BASyC™ and available for history reports and alerts.
AquaStat Pump Control
If so equipped, the AquaStat should be set in accordance with the design engineer’s instructions. According
to the CDC, running recirculation pumps continuously helps prevent legionella growth. Acorn Controls
agrees with this for many reasons and recommends that AquaStats be used as a high temp safety shutdown
in the event that something goes wrong with the system. We recommend setting this 10 degrees above the
mixing station setpoint.
Relay Pump Control
If equipped with this feature, your BASyC™ Mixing Valve Assembly includes recirculation pump control
via a relay output. This function is displayed, programmed and controlled through the BASyC™ software
and is typically in lieu of the AquaStat option available with the Command Station assembly. Acorn
typically provides a relay rated for the recirculation pump provided by Acorn. If Acorn did not provide the
recirculation pump, data on the pump must be provided upon ordering for this feature to be active. See
details later in this document on user-adjustable settings under “RECIRCULATION PUMP CONTROL”
later in this document.
Return Temperature Sensor
If equipped with the return temperature sensor option, your BASyC™ Mixing Valve Assembly includes a
temperature sensor in the return line. Data from this sensor will be stored and available for Data Reports
and available to trigger alerts.

ACORN CONTROLS / ACORNCONTROLVALVES.COM / 1.800.488.8999 15
Pressure Sensor
Data from the pressure sensors is captured and stored by BASyC™ and used to calculate and display
mixing station HW energy and ow as well as used for data Reports and to trigger alerts and alarms.
Flow and Hot Water BTU Data
If equipped with the Flow and BTU data capability, this data will be displayed on the portable operator
interface or operating overview screen. These values may be reset by clicking on the ow or BTU values
at the Operating Overview Screen and using the links that appear.
RECIRCULATION PUMP CONTROL
If equipped with a recirculation pump option, your
BASyC™ Mixing Valve Assembly may have been
ordered with recirculation pump control. This function
is displayed, programmed and controlled through the
BASyC™ software, in lieu of the AquaStat option
available with the Command Station assembly. Acorn
provides a relay rated for the recirculation pump
provided by Acorn. If Acorn did not provide the
recirculation pump, data on the pump must be provided
upon ordering for this feature to be active. See details
later in this document on user-adjustable settings under
“RECIRCULATION PUMP SETTINGS.”

ACORN CONTROLS / ACORNCONTROLVALVES.COM / 1.800.488.8999

If equipped with ow sensor capability, a clamp-on ow
meter is installed on the outlet of your mixing station, as
shown. The data from this ow meter is used to calculate
and display mixing station HW energy and ow, in lieu of
calculated ow using pressure sensors, as described earlier.
FLOW SENSOR
• Prior to starting up system make sure to ush pipes of debris.
• Open the isolation ball valves at the hot & cold inlets, the outlet and the return.
• Look at T/P gauges to make sure pressure is available at each.
Plug the Acorn BASyC™ unit
into a standard 120vac GFCI
protected outlet. Each BASyC™
unit is provided with a 6 ft.
electrical plug/wire to aid in
start-up. Care must be taken
so that the plug doesn’t get
pulled out during operation. It
is assumed and recommended
that after the unit is in
operation, a qualied electrician
will hardwire the unit per our
wiring diagram as shown here
and in accordance with any and
all local codes and standards.
STARTUP

ACORN CONTROLS / ACORNCONTROLVALVES.COM / 1.800.488.8999 17
Apply power to the cabinet and turn on the power switch inside the BASyC™ control cabinet.
When power is applied, the green status LED on the control module and the power LED on the I/O module
will light up. After 10-20 seconds, the amber, Beat LED on the Control module (power) will light up,
indicating the system is OK. If there are network connections and trafc, the primary and secondary LED’s will
ash indicating this also. The Beat LED will ash at 50/50 on/off duty cycle when the controller is functioning
properly. If it does not, contact Acorn technical support for assistance. The I/O module status LED will
next illuminate after another 10-20 seconds. After all these LED’s light as expected it will take another 5-10
minutes to boot, load software and begin normal operation. The rst indicator of this is that the D1 LED will
light up indicating the controller and software are working together properly. At this point any combination
of LED’s on the I/O module may or may not light up based on the conditions sensed by the software. D1
should always be on and if it is not, contact Acorn technical support for assistance.
If the Acorn BASyC™ is factory pre-congured, please skip ahead to either the Web Browser Access or the

In order to utilize the email alarms & alerts, the BASyC unit must be connected to an active LAN. Generally,
you will need to work with the local IT staff to determine what the appropriate IP, subnet mask and default
gateway addresses are.
The easiest/most straightforward way to make these network settings is to use the optional handheld LCD
display/controller. All units ship from the factory preset with a 4 digit LCD passcode of ‘0101’ to access the
system. If your system is precongured, please refer to your documentation or contact your local administer
to obtain the appropriate passcode to access BASyC™ via the LCD interface.
Using LCD display/controller
Using the wire provided, plug the RJ11 jacks into the back of the LCD display and into the control module as
shown below.
After plugging the LCD unit it should beep and start-up at the passcode screen as shown below.
