ModSync Features
ModSync has been specifically designed for use with multiple condensing boilers to maximize the efficiency of the hydronic system. ModSync provides outdoor reset functionality to adjust the hydronic loop temperature setpoint based on the measured outdoor temperature. As the outdoor temperature increases, ModSync automatically decreases the hydronic loop setpoint. Lower loop temperatures during warmer days allow for significant energy savings and efficiency gains while still maintaining building comfort levels. ModSync also provides independent outdoor reset functions - each with unique user defined variables - based on "Occupied" and "Unoccupied" building status.
Intelligent Lead/Lag
Lead/lag designs are used with multiple boiler installations to maintain an even number of operating cycles and run hours across all of the boilers in the system. Traditional sequencing systems rotate the boilers based on a random time schedule. This control technique is flawed in that it does not take into account any operational history of the boilers in the loop.
ModSync solves this issue through a patent-pending intelligent lead/lag technology that automatically assigns the lead/lag positions based on each boiler’s operating history, keeping a consistent number of cycles/run hours across all stages. ModSync’s intelligent Lead/Lag technology provides peace of mind that your boiler or heater system is being controlled and operated to its optimal potential.
Customizable
ModSync is perfect for applications involving condensing and non-condensing (hybrid) boiler designs. The control logic is designed to take advantage of the condensing boiler during shoulder loads and bring the non-condensing boilers online only during the peak design days.
Additional control options include: boiler isolation valves, primary/secondary pumps, common Hydronic/DHW boiler loops, process valve control and integration with multiple types of boiler designs.
ModSync's control logic can also be customized for use with multiple steam boiler and thermal fluid heater applications.
Ease of Use
ModSync combines sophisticated control capabilities with a user-friendly, easily configured touchscreen interface. A “Question and Answer” setup feature eliminates the guesswork and simplifies system start-up.
Remote Monitoring
Remote access capabilities with inSite allow ModSync to be monitored and configured using a LAN or WAN connection. Smart-phone compatibility provides another solution for monitoring system variables.
Outdoor Reset
The system setpoint is automatically adjusted based on outdoor temperature. Warmer outdoor temperatures lower the hydronic loop setpoint, increasing system efficiency.
Setback Scheduling
The loop setpoint can be configured to change based on occupancy of the building. This allows for automatic switchover to lower operating temperatures during off hours such as nights, weekends and holidays.
System Interface Flexibility
ModSync can be custom programmed by in-house specialists to match your most demanding system design requirements, eliminating “canned logic” limitations.
Multiple Setpoint Modes
Easily select between ModSync Outdoor Reset, Remote Setpoint (4-20mA, 0 –10VDC), E/BMS Communication or Manual setpoint modes through ModSync touchscreen.
Trending
Key variables such as Supply Temperature, Return Temperature and Setpoint can be trended to show system response and performance data.
Alarm Status and History
Alarm status is easily communicated with a text description of the current alarm. No alarm code deciphering or cross-referencing is required. The Alarm History features provide a date and time stamp of any recent alarm conditions.
Building Integration
ModSync can be configured to communicate with Energy/Building Management Systems using Modbus, BACnet, Lonworks or N2 protocols.
Text Messaging
A text message can be sent to as many as six numbers if an alarm condition occurs. Query information about the boiler loop status by sending a text message to ModSync.
Wireless Interfacing
Wireless modules can be provided to interface between ModSync, the Boilers and the Energy/Building Management System. Wireless installations decrease installation time considerably and simplify retrofit boiler opportunities.
