User’s Information Manual

4SMART SYSTEM control module (continued)

A: General

Boiler model

The control will display “Knight Boiler” as the model number because the same control is used on several models. This will be displayed when parameter A1 has been accessed. This parameter is not changeable.

User code

The User Code allows the user to access and change a limited number of control parameters. The access code can be changed by the user or the installer to a code of their choosing. To change the code, parameter A2 must be accessed. The default code is 0704. The code can be changed one digit at a time by using the arrow keys on the display.

Date and time

The control uses an internal clock for the night setback feature and for logging of events. For these features to work correctly, the clock must be set when the boiler is first installed or anytime the boiler has been powered off for more than 30 days. To set the clock, parameter A3 must be accessed. The date and time are displayed as “YY:MM:DD W hh:mm”. YY = year, MM = month, DD = date, W = day (1 = Sunday, 2 = Monday, etc.), hh = hour (24 hour time; 2:00 PM = 14:00), mm = minutes.

NOTICE

The internal clock does not adjust for

Daylight Savings Time and therefore,

 

 

will require a manual adjustment.

Software version

The software version allows the user to view the software version in use by the control. This software controls the operation of the boiler. When a new software version becomes available, the existing control can be replaced with a new control to update the software.

Temperature units

The control can be configured to display temperature in either °C or °F. This parameter can be changed by the user or the installer by accessing parameter A5. The default is °F.

Night setback temperature

Once the internal clock has been set correctly, the night setback feature can be used to program a lower water temperature set point for space heating. This parameter can be changed by the user or the installer by accessing parameter A6. The temperature range for this parameter is 32°F to 140°F. The feature is turned off with a setting of 32°F. The default value is 32°F.

Night setback times

If parameter A6 is set to anything other than 32°F, the night setback feature becomes active. This will require start and stop times to be programmed for the days that reduced temperatures are required. These times can be changed by the user or the installer by accessing parameter A7. Each day of the week (Sunday through Saturday) will have an on and off time.

Example: Monday ON: 22:30, Tuesday OFF: 6:45. If you wish to skip a day and have no night setback, leave the on and off times the same. The default times for each day will be 00:00 (midnight).

B: Temperature settings

SH set point user

The SH set point user sets the water temperature set point for fixed operation or the maximum temperature set point when the outdoor air sensor is used. This parameter can be changed by the user or the installer by accessing parameter B1. The temperature range of this parameter is 50°F to 190°F. The default value is 125°F.

C: Data logging

Hours running SH

The hours running SH parameter shows the total number of hours the boiler has been in the SH firing position. This parameter can be viewed by the user and the installer by accessing parameter C1.

Hours running DHW

The hours running DHW parameter shows the total number of hours the boiler has been in the DHW firing position. This parameter can be viewed by the user and the installer by accessing parameter C2.

Ignition attempts

The ignition attempts parameter shows the total number of times the boiler has attempted to fire. This parameter can be viewed by the user and the installer by accessing parameter C3.

Show last 10 errors

The control will log the 10 most current errors with the date and time the error occurred. This parameter can be viewed by the user and the installer by accessing parameter C4.

With an annual fuel utilization efficiency (AFUE) rating that can exceed 95%, users can expect significant savings on energy costs while reducing their carbon footprint.

Another important characteristic of the Lochinvar 80 - 285 is its stainless steel heat exchanger. The use of stainless steel not only enhances durability but also ensures longer life expectancy and resistance to corrosion. This makes it an excellent choice for harsh environments or areas with hard water. Furthermore, the design of the heat exchanger promotes optimal thermal performance and efficient heat transfer, ensuring that the system operates at peak efficiency.

The Lochinvar 80 - 285 series also incorporates intelligent controls, allowing for enhanced operation and management of heating systems. The intuitive user interface provides easy access to critical system information, allowing users to monitor performance and make adjustments as needed. The built-in diagnostic tools help in troubleshooting and maintaining optimal performance, minimizing downtime and service costs.

Moreover, the boiler is designed with a flexible venting system. It can be vented vertically or horizontally, offering installation versatility for various building configurations. This adaptability makes it a favorite among contractors and engineers, simplifying the installation process and reducing labor costs.

The Lochinvar 80 - 285 series prioritizes safety as well. It comes equipped with multiple safety features, including flame monitoring and automatic shut-off valves, ensuring that the system operates safely under all conditions. Additionally, its low emissions design contributes to a cleaner environment by complying with stringent emission standards.

In summary, the Lochinvar 80 - 285 series stands out for its high efficiency, durability, and user-friendly technology. With its advanced condensing technology, stainless steel heat exchanger, intelligent controls, and versatile installation options, it is a dependable choice for anyone seeking a reliable heating solution that prioritizes performance and sustainability.
