E8 Unit Controller

A standard component included with all Modulex units, the E8 controller is responsible for the staging and modulation of individual thermal heating modules in a Modulex boiler. In addition, this microprocessor monitors supply and return water temperatures and domestic hot water zones. The E8 controller:

• Shares the heating load among as many of the boiler’s thermal heating modules as possible. Running multiple modules at minimum ouput maximizes the overall operating efficiency of the boiler;
• Provides access to all testing/programming parameters of each individual heating module: operation test, operation time, boiler freeze protection and pump’s anti seize program;
• Drives lead-lag burner operation based on operating hours. The boiler module with the least burner operating hours is the first to start and the burner with the most operating hours is the first to stop;
• Supports DHW production using a dedicated sensor to control a dedicated pump or 3-way diverting valve for storage tank temperature control;
• Supports a manual operation service mode to control individual modules during troubleshooting or combustion calibration procedures;
• Drives diagnostics such as relay and senor testing;
• Supports Modbus integration with AERO BMS or Building Automation Systems. AERCO also offers a Communication Gateway to support BACnet, Lonworks* and N2 system integration.

Mounted on the front of each unit, the compact E8 controller features a rotary knob and LCD function display to support set-up, operations and troubleshooting for the Modulex boiler.
