Excel 10 Boiler Interface Controller - The boiler interface controller for this appliance is based on the Excel 10 controller platform with unique software customized for operation of the Lochinvar Intelli-Fin. The Excel 10 is also compatible with LonWorks® building management systems. All of the appliances’ internal safety, operating and ignition controls interface with the Excel 10 controller. Local communication, programming and a digital display of the appliance functions and operating conditions are accessible through a Command Display. The Command Display is mounted on the front control panel of the appliance as shipped from the manufacturer. If multiple Intelli-Finappliances are to be installed in a single application, see “Multiple Appliance Installations” for information on interfacing, sequencing and display of multiple Intelli-Finappliances.

NOTE:

A single Command Display is shipped for each job site installation with up to 16 Intelli-Finappliances. A single Command Display is used to display and access the operating conditions of up to 16 Intelli-Finappliances.

The Excel 10 Boiler Interface Control serves as the operating temperature control to regulate the amount of heat added to the water system for both heating boilers and potable water heaters. Custom software programmed into the Excel 10 will determine the proper operating profile for your specific application. Ensure that an Intelli-Finis properly applied. A unit ordered as a heating boiler must be applied as a heating boiler and a unit ordered as a potable water heater must be applied as a water heater. The Excel 10 Boiler Interface Control provides on/off control of the gas supply to the burner, operation of a VFD to control a variable speed combustion air blower, interface with the ignition control system, on/off control of the integral circulating pump, operation

of a floating point bypass valve, control of water temperature set points, and monitoring of all safety functions. The operation and status of these and all related functions are displayed on the Command Display.

The Excel 10 has a single LED located in the middle of the control module. In normal operation of a boiler equipped with an optional outdoor reset function, this LED will blink at the rate of one blink per second. Active alarms will blink this service LED at a faster than normal rate of two blinks per second to indicate an alarm. The alarms which are displayed in this manner are: Network communications failure, sensor failure, hard lockout, water flow failure, low air, blocked drain, low/high gas pressure, flame failure, soft lockout, heat mode failure, high temperature alarm, and boiler not operational. A boiler that is not equipped with the outdoor reset function or a water heater will always blink the LED at the faster rate of approximately two blinks per second. This LED is not to

be used as a diagnostic indicator.

The Excel 10 controller is mounted on the backside of the front control panel that mounts the Command Display and the Ignition Control Module. This panel is hinged on the right side so it can be exposed for viewing and service. All connections from the appliance safety and operating controls to the Excel 10 are accomplished with multiple wiring harnesses. Each wiring harness is connected to unique multiple pin terminations to ensure proper connection of all components. The multiple termination points are located on two printed circuit boards mounted on either side of the Excel 10 controller. Use caution when connecting or disconnecting wires at the plug in terminals to prevent damage to the printed circuit boards.

There is a bar code label on the back of the Intelli-Finnear the terminal connections. This is the Neuron I.D. label which identifies the exact numerical sequence applied to the Excel 10 control installed in the boiler/water heater. This information is required for the local/remote communication network. The numerical sequence
