Touch Screen LCD Display
• Simple setup! Requires only four inputs (boiler minimum and
maximum water temperatures and outdoor air minimum and
maximum temperatures)
• Boiler status, settings, and diagnostic information are all
accessible from the display in simple English text.
• Control settings can be adjusted from the display, advanced
settings are password protected.
• Built-in diagnostics allow simple trouble-shooting.
• No external laptop computer required for setup or adjustments,
both can be accomplished via the LCD display.
• Display turns red in the event of error or blackout. Blinking
buttons guide the user through diagnostic screens that explain
the issue and how to resolve or repair the issue. Help screens
are provided, offering detailed explanations of each setting in
simple terms that are easy to understand.
Control Data Logging
• Can display and recall information from numerous control
parameters.
• Previous five (5) lock-out events can be recalled on the display.
Real time trending tracks the following four parameters: Supply
Temperature, Return Temperature, Flame Signal, and Boiler
Firing Rate in a running graphic display.
• Logs runtime hours for the boiler as well as the number of
cycles for the boiler, the boiler pump, the DHW pump, and the
system pump. This information can assist in diagnosing both
boiler and system issues, saving valuable time on service calls.
Outdoor Reset
• Adjusts boiler temperature based on the outdoor temperature.
• Helps to keep the boiler in condensing mode longer, resulting
in higher efficiency.
• Improves comfort by reducing overheating of the zones.
• Easily adjustable, using simple parameters (outdoor high and
low temperatures, and boiler high and low temperatures).
Domestic Priority with Priority
Protection
• Directs boiler output to the indirect water heater in order to
minimize recovery time.
• Priority Protection is provided to allow the boiler to continue
heating the building in the event of excessive domestic hot
water demand.
Control Flexibility
• Responds to multiple heating demands, and features
adjustable pump outputs, allowing for greater installation and
piping flexibility.
• Pump outputs can be selected and adjusted for the boiler, the
system, and the domestic hot water pumps.
Adaptable Firing Rate Output
• Allows the boiler’s output to be adjusted for varying heat loads
connected to the system.
• Reduces boiler cycling, wear and tear on parts, and enhances
heating efficiency and comfort.
Multiple Firing Rate Sensor Options
• Accommodates piping arrangements that are better suited
to select the firing rate of the boiler based on the header
temperature, rather than the boiler supply temperature.
• Enhances the versatility of the Apex boiler by integrating into
existing systems without requiring additional controls.
Warm Weather Shutdown
• Ideal for commercial installations that maintain heating loop
temperatures year round.
• Can be adjusted to allow the heating loop to cool when the
outdoor temperature reaches a specified temperature.
• Reduces unnecessary boiler/pump cycling and standby losses.
but will still respond to DHW demands.
Freeze Protection
• If possible freezing water temperatures are detected, the ABC
System will operate all pumps connected to the boiler. If water
temperatures continue to drop, the boiler will fire and warm
the system slightly in order to prevent freezing and damage to
the system.
Pump Exercise
• Circulators connected to the ABC System control that don't
operate for seven (7) days, are activated to run for ten (10)
seconds.
• Reduces the possibility for pumps to seize and fail due to long
periods of inactivity, improving the overall reliability of the
heating system.
Apex Boiler Control…
Features Beyond Compare.
The Apex Boiler Control System is the next generation of advanced electronic controls designed specifically for condensing boilers. The
ABC System was designed with many features that make the control simple to understand and use, as well as features that optimize
boiler performance, flexibility and overall system efficiency and reliability. The ABC System is simply the most powerful, versatile, and user-
friendly boiler control available.
