Page 4: Principle Of Operation
NEUTON™ PUMP MODULE PRINCIPLE OF OPERATION Cooling Mode (4 pipe primary loop shown) Note: Only one of NEUTON™ is the HVAC industry’s first smart, plug-and- multiple beams in play controlled chilled beam pump module (CCBPM) zone shown. for reducing chilled beam system installation and operational costs . -
Page 5: Sequence Of Operation
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 . -

Page 25: Troubleshooting
NEUTON™ TROUBLESHOOTING Problem Action Pump Air Locks The pump is vented by rotating the center screw on the pump a single turn counterclockwise (See Figure 11) and allowing a drop of water to escape . Tighten the vent screw when complete . No flow/movement in actuator Check valve and actuator replacement to ensure valve and actuator are aligned properly . - Page 26 NEUTON™ PUMP MODULE Valve and Actuator Replacement Should for any reason the control valves need replacing follow this procedure . Note the orientation and rotation of the valve bodies are not the same . Failure to install the valves and actuators properly will result in loss of functionality .
- Page 27 NEUTON™ Chilled Water 3-Way Valve Actuator Replacement Figure 14 As shown in the chilled water valve is a 3 way mixing valve with the same type Belimo actuator as used on the hot water valve . When replacing the actuator be sure to disconnect power to the unit .
