Building Automation Controls Groups
General Overview
For over 10 years Binsky and Snyder Service, Inc. has worked on pneumatic, electric, and computer based building automation control systems. We perform maintenance on existing control systems and the installation of new systems.
Our list of satisfied clients include state universities, property owners and property management companies.
In 1993 we became a Honeywell authorized Automation And Control Specialist (ACS) contractor. Since then we have used the Honeywell Excel 5000 controls for most of our installations. We have systems installed in office buildings, university labs, elementary schools, and hospitals. We have factory-trained technicians that are knowledgeable in the installation and service of the Honeywell Excel 5000 system and the related out gear.
Our control designers work with Honeywell licensed software application, design, and development tools at our facility to build and test all of our designs and specified systems. To ensure product and system reliability to the end user all designs are tested with current available product before installation. Wiring diagrams and submittals for all projects are developed by our in-house staff and then relayed to our field technicians along with start up and commissioning manuals.
Field wiring to Control Panels and System Controls is installed under the supervision of a licensed electrician. Final wiring connections to system sensors and controllers is made by our trained field technicians. When all wiring is completed the entire system is calibrated, tested and started.
End user training is conducted at the client's site after the control system is commissioned. End user training consists of a review of operation and maintenance manuals which are supplied by our company. Training in the use and daily care of the control system is conducted by our control system designers. If the client so chooses designed software licenses can be purchased and instruction in the Honeywell care design software can be obtained.
Binsky and Snyder Service Inc. offer's annual maintenance agreements on newly installed or existing control systems. Our maintenance agreements consist of daily, weekly or monthly system monitoring. Binsky and Snyder Service Inc. operations and maintenance engineers can be contracted to be at the client's site on a daily basis. Annual software upgrades to ensure system reliability are offered and installed in a personal computer at the client's site or off site for monitoring purposes.
Honeywell Inc. provides our company with updated training seminars, software upgrades, and design advice when necessary.
We will gladly visit your site and make a survey of your existing systems. We will look for areas were we can reduce your energy usage and improve comfort levels. During our survey we will check the condition of your equipment, and how the equipment is controlled. We will discuss with you the items that you feel need to be improved and what changes we can make to improve your system.
The Star Ledger - Newark, NJ
Binsky & Snyder service designed and installed a complete Honeywell energy management system using XL500 and XL100 controllers, and XL10 VAV box controllers. The operator workstation is a text version of Excel Building Supervisor (XBS). There is also an XM100 modem module for remote communications.
The Star Ledger saw reduction in their utility costs after our control system was installed. XL10 controllers were installed on the VAV boxes, and variable speed drives were installed on the supply and return fans. The air flow and temperature setpoints for individual VAV box controllers are reset when the space it serves is unoccupied. The air handlers now move less air. As a result less air is being conditioned in the air handlers. This resulted in less demand on the boilers and chillers.
The VAV box controllers and air handler controllers are all on a network. The operating engineer can see what the entire system is doing from one central PC based operator workstation. The system can also be accessed remotely through a phone modem.
Rutgers University, Olsen Hall - Newark, NJ
The system uses seven XL500 controllers to monitor and control 430 physical points. The operator workstation is a graphics version of Excel Building Supervisor (XBS). There is also an XM100 modem module for remote communications.
There are 35 chemistry labs in the building. There are 78 lab hood exhaust fans that ran continuously. The small hoods have single exhaust fans and larger hoods have dual exhaust fans. Two constant volume air handlers supplied conditioned 100 % outside air to the labs. Each lab had a reheat coil in the supply duct controlled by a room thermostat. A constant volume air handler supplied 100 % outside air make up to the lab hoods.
Variable speed drives were installed on the air handlers. Two speed motors were installed on the exhaust fans that served small hoods with single exhaust fans. A relay wired to the lights in each lab signaled to the BAS when the lights are turned on. Motorized dampers were installed in the supply ducts for each lab.
A static pressure sensor located in the supply duct through the Control System modulates each variable speed drive. Another static pressure transmitter through the Control System modulates the makeup air damper in each lab to keep the pressure in the room below the pressure in the hallway.
When the lab is unoccupied the two speed exhaust fans in that lab switch to low speed and one fan shuts off in the large lab hood. The Control System maintains space temperature by modulating a supply air damper and reheat coil in the lab to maintain the unoccupied room temperature setpoint.
When the lab is occupied the two-speed exhaust fans in that lab switch to high speed and both fans in the large lab hood start. The Control System maintains space temperature by modulating a supply air damper and reheat coil in the lab to maintain the occupied room temperature setpoint.
