The control shall be equipped with a multi-color linear LED light to indicate the level of firing and/or air/fuel valve position.

The control shall display two temperatures using two dedicated three-digit seven-segment displays.

The control shall offer an Enable/Disable toggle switch as well as two buttons for Testing and Resetting the Low Water Cutoff.

The Manager designated boiler control shall be capable of the following functions without the need for additional external controls:

Sequence up to 16 boilers,

Control boiler pumps and/or modulating motorized valves,

Building Automation: The control shall be able to communicate to Building Management Systems using RS485 and communicate using Modbus RTU protocol.

The control system shall be segregated into three components: Edge [i] Control Panel, Power Panel and Input/Output Connection Box. The entire system shall be Underwriters Laboratories recognized

The control panel shall consist of seven individual circuit boards using surface-mount technology in a single enclosure. Each board shall be individually field replaceable. These circuit boards shall include:

A microcontroller board with integrated 5-inch touchscreen color display providing the user interface.

A 7-segment display board. This board includes two 3-digit 7-segment displays. These displays shall be used to view a variety of temperature sensor values and operating and startup function status.

An Interface board connects the microcontroller board to internal components using ribbon cables.

An electric low-water cutoff board connects to the test and manual reset functions on the microcontroller board.

A power supply board is designed to provide the different DC voltages to the rest of the boards. It also acts as voltage regulator and reduce power noise.

An ignition and combustion board. This board controls the air/fuel valve and Safety Shutoff Valve, flame status and ignition transformer

A connector board used to connect all external electrical connection.

Control settings transfer using USB: The control shall simplify and significantly lessen startup and boiler setting time by being able to use a USB flash drive to copy settings from one boiler to another boiler. Installers shall use successfully preconfigured boiler settings in their portfolio to newly installed boilers.

Combustion calibration: The control shall offer at least 5 calibration points. The use of less than 5 calibration points is not permitted to improve overall system efficiency under all firing rates. Each combustion calibration point shall operate with 5 to 7% O2 levels to improve operating efficiency. Deviating away from these values shall not be acceptable.

Unit and Plant Status: The control shall provide a quick view of the unit status and plant status.

The unit status screen shall provide temperature setpoint, all water inlet and outlet and supply air and exhaust temperature sensors values. It shall also provide unit current and target firing rates. Additional screens shall display unit run hours, cycle count and average cycles per hour.

The controls shall annunciate boiler and sensor status and include extensive self-diagnostic capabilities.

The control panel shall incorporate three self-governing features designed to enhance operation in external control modes. When operating by an external control signal, the control panel can work to eliminate nuisance faults, such as over-temperature, resulting from improper external signal or loss of external signal. These features include:

Setpoint High Limit: Setpoint high limit allows for a selectable maximum boiler outlet temperature and acts as temperature limiting governor. Setpoint limit is based on a PID function that automatically limits firing rate to maintain outlet temperature within a 0-to-10-degree selectable band from the desired maximum boiler outlet temperature.

Setpoint Low Limit: Allow for a selectable minimum operating temperature.

Failsafe Mode: Failsafe mode allows the boiler to switch its mode to operate from an internal setpoint if its external control signal is lost, rather than shut off. This is a selectable mode, enabling the control to shut off the unit upon loss of external signal, if so desired.

The boiler control system shall incorporate the following additional features for enhanced external system interface:

System start temperature feature

Pump delay timer

Remote interlock circuit

Delayed interlock circuit

Delta-T Limiter

Freeze protection

Warm-weather shutdown

The control shall offer multi-level user security access using different passwords. For additional security, the passwords shall expire if control display was not touched for an extended period 30 minutes.

Each boiler shall include an electric, single-seated combination safety shutoff valve/regulator with proof of closure switch in its gas train. Each boiler shall incorporate dual over-temperature protection with manual reset, in accordance with ASME Section IV and CSD 1.

Each boiler shall be equipped with TComp combustion air temperature compensation. If the combustion air temperature changes, the control system will automatically compensate for air density changes by adjusting the blower speed. This will adjust oxygen and optimize the combustion efficiency under all seasonal temperature changes. Boilers without air temperature compensation shall be deemed unacceptable.

Each boiler shall be onAER ready with a standard Ethernet port and include a 5-year onAER subscription at no additional charge. AERCO s onAER service grants the user online access to real time operation and status of their system plant from any computer, tablet or mobile device along with the following capabilities:

Option to manually designate lead and last boiler

Designated manager control, used to display and adjust key system parameters.

Automatic bump-less transfer of manager function to next unit on the chain in case of designated manager unit failure; manager/client status should be shown on the individual unit displays.

For boiler plants greater than 16 units, the Boiler Manufacturer shall supply as part of the boiler package a completely integrated AERCO Control System (ACS) to control all operation and energy input of the multiple boiler heating plant. The ACS shall be comprised of a microprocessor-based control utilizing the MODBUS protocol to communicate with the Boilers via the RS-485 port. One ACS controller shall have the ability to operate up to 32 AERCO boilers.

The controller shall have the ability to vary the firing rate and energy input of each individual boiler throughout its full modulating range to maximize the condensing capability and thermal efficiency output of the entire heating plant. The ACS shall control the boiler outlet header temperature within +2ºF. The controller shall be a PID type controller and uses Ramp Up/Ramp Down control algorithm for accurate temperature control with excellent variable load response. The ACS controller shall provide contact closure for auxiliary equipment such as system pumps and combustion air inlet dampers based upon outdoor air temperature.

The ACS shall have the following anti-cycling features:

Manual designation of lead boiler and last boiler.

Lead boiler rotation at user-specified time interval.

Delay the firing/shutting down of boilers when header temperature within a predefined deadband.

When set on Internal Setpoint Mode, temperature control setpoint on the ACS shall be fully field adjustable from 50ºF to 190ºF in operation. When set on Indoor/Outdoor Reset Mode, the ACS will operate on an adjustable inverse ratio in response to outdoor temperature to control the main header temperature. Reset ratio shall be fully field adjustable from 0.3 to 3.0 in operation. When set on 4ma to 20ma Temperature Control Mode, the ACS will operate the plant to vary header temperature setpoint linearly as an externally applied 4-20 ma signal is supplied.

When set on MODBUS Temperature Control Mode, the ACS will operate the plant to vary header temperature setpoint as an external communication utilizing the MODBUS protocol is supplied via the RS-232 port. The ACS controller shall have a vacuum fluorescent display for monitoring of all sensors and interlocks. Non-volatile memory backup of all control parameters shall be internally provided as standard. The controller will automatically balance the sequence of operating time on each boiler by a first-on first-off mode and provide for setback and remote alarm contacts.
