OWNER’S MANUAL
NEUTON™PUMP MODULE
PRINCIPLE OF OPERATION
NEUTON™ is the HVAC industry’s first smart, plug-and-
play controlled chilled beam pump module (CCBPM)
for reducing chilled beam system installation and
operational costs.
NEUTON™ is a factory-built and pre-tested CCBPM
package complete with its own powered integrated direct
digital controller, chilled and hot water connections,
valves, variable-speed electronically commutated motor
(ECM) pumps, zone sensors, and other unique features.
The device provides active condensation control
effectively addressing one of the key design concerns
regarding active chilled beams.
The intuitiveness of NEUTON™ eliminates the expense
of a separate chiller, boiler and secondary water
distribution system associated with conventional chilled
beam HVAC designs. Instead of expensive secondary
piping loops, each NEUTON™ blends and re-circulates
return water within its zone to convert typical 42°F and
140°F primary loop water temperatures to optimal 58°F
or 100°F chilled beam discharge temperatures, which
prevents cooling mode condensation and heating season
heat stratification.
Each NEUTON™ can control up to 10 chilled beams,
depending upon the water flow rate required.
Numerous important design advantages are provided by
the combination of Pinnacle systems with active chilled
beams including:
• Very high energy efficiency
• Very low primary airflow requirements
• Low noise levels
• Reduced filter maintenance – central location not
room by room
• Ideal air distribution
• Improved indoor air quality – excellent outdoor air
delivery
• Ideal humidity control
• Active condensation control

OWNER’S MANUAL
NEUTON™
SEQUENCE OF OPERATION
NEUTON™ receives space conditions and setpoints from either a communicating wall mount ZS Pro Zone Sensor or
from the Building Automation System (BAS). The sequence begins when power is applied to the controller. The BAS
can override the controller operation with a stop command.
The controller modulates the chilled and hot water valves to maintain the desired supply water temperature to the
chilled beams. The water flow is modulated to maintain the desired space temperature setpoint. The controller
accepts occupied and unoccupied setpoints, which may be entered either at the zone sensor, or through the BAS.
Occupied mode is initiated either by a digital input, a call from the BAS, by space CO2exceeding the “CO2force occupied
mode setpoint,” or by the override button on the thermostat.
On call for cooling, the chilled water valve modulates to produce the “cooling beginning water temperature” setpoint.
On continued call for cooling, the pump operates at the default mid-range pump speed for a short duration and the
control valves modulate, as required, to achieve the desired beam supply water temperature setpoint.
After a default time delay, if the space cooling setpoint is not achieved or if it is exceeded beyond the deadband
parameters set, the pump speed is modulated between the “Cooling Minimum Pump Output %” and the “Max Pump
Demand” setpoint until space conditions are achieved.
If after reaching maximum pump speed the space cooling setpoint is not achieved, after a time delay, and on continued
call for cooling the water temperature delivered to the beams will be gradually reset until it is equal to the space
dewpoint plus the “water offset above dew-point” setpoint.
On call for heating, the hot water valve modulates to produce the “Heating Beginning Water Temperature” setpoint. On
continued call for heating the water temperature delivered to the beams will be gradually reset until it reaches 100°F.
The pump is running at the “heating minimum pump output %” setpoint while the water temperature is being reset.
When the water temperature reaches 100°F (adj.), and if the space heating setpoint is not reached, the pump demand
will modulate from its heating minimum pump output % setpoint up to the “max pump demand” (if needed) to reach the
space heating setpoint temperature.

OWNER’S MANUAL
NEUTON™PUMP MODULE
1) A control panel penetration/bushing will need to
be inserted to accommodate the BAS and/or zone
sensor wiring. Installer should determine optimal
positioning per final installation orientation. The
use of a knockout punch is recommended for
penetration(s). Install bushing.
NOTE: Take care to keep the inside of the control
panel free of metal shavings when installing hole.
2) Mount unit to an appropriate bracing system. The
pump module can be mounted in any position that
allows the pump shaft to be oriented horizontally
while not allowing the terminal box be oriented
in a downward position (See Figure 3). See the
dimensional drawings in Figures 1D and 2D for the
dimensions between the four (4) mounting holes
for each configuration. At a minimum, 12” should
be added to the width and 8” to the depth shown
to allow reasonable service access to the pump
and the valves and to allow for a full swing of the
electrical panel door.
3) Disconnect the o-rings that are attached to the unit
and place on each pipe connection (See FIgure 4).
INSTALLATION & WIRING
RECEIVING & INSPECTION
Upon delivery, confirm that the quantity and model(s) received matches the Bill of Lading. If there is any discrepancy,
immediately notify SEMCO LLC.
Inspect the packages for signs of damage. If damage is suspected, contact SEMCO immediately. If no visible damage
is apparent, the unit should be properly stored until installation.
FIGURE 3. Acceptable (A, B, E) and unacceptable (C, D) mounting orientations. Note that orientation C can be utilized provided that
the pump motor is field rotated to an acceptable position (E).
A B C D
4) Make pipe connections. See the dimensional
drawings in Figures 1A and 2A for the dimensions
between pipes. All piping connection ports on
NEUTON are 1” female National Pipe Tapered
(NPT) swivel half-union adapters with face gasket
designed to connect to standard 1” male National
Pipe Tapered fittings (NFT) to be provided by the
installing contractor. Tighten the swivel nut by hand
and then gently snug with pliers (1/8 to ¼ turn) for a
leak-free joint. Do not over-tighten or you may cut
the gasket and cause a leak.
5) WARNING! Air in the system will damage the pump:
air must be completely eliminated from the pump
module and chilled beam loop using a vent at the
high point. The actuator control valves must be
manually opened to facilitate filling the system (See
Figure 5). After the system is filled, the valve should
be returned to automatic operation. Be sure the
knob has “popped” out to the engaged position to
return to automatic mode. See Figure 6 for position
of valve knob and rotation direction switch after

BACnet MS/TP communications are set up at the controller.
See the legend in the center of the I/O Zone 583 for baud rate
selection and protocol.
Available baud rates are 9600, 1.92 K, 38.4 K, and
75.8 K BPS.
Additional available protocols are N2 and Modbus.
The MAC address is set with the rotary dials on the upper left
side of the controller (See Figure 7). The device ID will be 2400
+ the MAC address.
If a different device ID is required, a BACview6keypad must be
used to either enter a specific ID or change the Base ID.
ZS Pro Zone Sensor
The ZS Pro Zone Sensor monitors space temperature and
dewpoint to provide active condensation control while
continuing to provide space heating and cooling. Information
such as zone temperature, setpoints, outside air temperature,
and equipment status can be viewed on the display. The
controls allow you to make the zone warmer or cooler or
override the schedule to put the zone in an occupied state.
When the green LED is lit, the zone is in an occupied state.
The ZS Pro Zone Sensor is designed for integration with the
I/O Zone 583 DDC controller. Communications are established
using the Rnet communications port and only a 4 wire
connection is required.
If the CCBPM is connected to a network via BACnet and/or
the zone conditions are provided to the pump module in this
manner, an additional connection is easily made at the BACnet
communications port standard at the 583 DDC controller. See
electrical diagram provided.
The control program determines what screens you see, what
information is in each screen, and what you can adjust. The
type of sensor also determines what you see. For example, if
the sensor reads temperature, humidity, and CO2, the Home
screen may cycle through the current values.
