A: General Heater model The control will display “LOCHINVAR” 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. 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 or tank. This parameter can be changed by the user or the installer by accessing parameter A6. The temperature range for this parameter is 32°F (0°C) to 140°F (60°C). The feature is turned off with a setting of 32.0°F (0°C). The default value is 32.0°F (0°C). Night setback times If parameter B6 is set to anything other than 32.0°F (0°C), 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 (Monday through Sunday) 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 08:00 (OFF) and 18:00 (ON). B: Temperature settings (boiler only) 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 unit is first installed or any time the unit 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 = Monday, 2 = Tuesday, etc.), hh = hour (24 hour time; 2:00 PM = 14:00), mm = minutes. 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 60°F (15°C) to 230°F (110°C). The default value is 120°F (49°C). C: Data logging The internal clock does not adjust for Daylight Savings Time and therefore, will require a manual adjustment. Hours running SH The hours running SH parameter shows the total number of hours the unit has been in the SH firing position. This parameter can be viewed by the user and the installer by accessing parameter C1. The software version allows the user to view the software version in use by the control.

This parameter can be viewed by the user and the installer by accessing parameter C4. 11 User’s Information Manual 3 SMART SYSTEM control module E: DHW settings F: Outdoor air reset (boiler only) DHW tank set point When a temperature sensor is installed in the DHW tank, the DHW tank set point sets the target temperature of the water in the tank. The user or installer can adjust this set point by accessing parameter E1. The temperature range of this parameter is 60°F (15°C) to 190°F (88°C). The default value is 120°F (49°C). Outdoor air shutdown DHW boiler set point (boiler only) When a DHW call for heat becomes active, the control will use the DHW boiler set point to determine the firing rate of the unit based on the actual outlet water temperature. This parameter can be changed by the installer by accessing parameter E2. The temperature range of this parameter is 60°F (15°C) to 200°F (93°C). The default value is 180°F (82°C). SH/DHW switching time (boiler only) The SH/DHW switching time parameter sets the length of time the control will stay in DHW Mode when a space heating (SH) call has been received. After this time period has expired the control will revert to SH Mode. If a DHW call is still active the timer will reset. After the time period has expired the control will revert back to DHW Mode. This will continue until one of the demands has been satisfied. This parameter can be changed by the installer by accessing parameter E3. The time range of this parameter is 10 minutes to 240 minutes. The default value is 30 minutes. When the outdoor temperature rises above this point, the control will block all SH demands (DHW demands will still be active). This parameter can be changed by the user or the installer by accessing parameter F5. The temperature range of this parameter is 0°F (-18°C) to 120°F (49°C). The default value is 80°F (27°C). Outdoor air shutdown differential The outdoor air shutdown differential parameter is the number of degrees below parameter F5 the outdoor air temperature must go before the unit will respond to a SH demand. This parameter can be changed by the user or the installer by accessing parameter F6. The temperature range of this parameter is 0°F (0°C) to 90°F (50°C). The default value is 10°F (5°C). Boost temperature If a SH demand lasts longer than the programmed time delay setting (F9) and there have been no DHW demands, the control will increase the water temperature set point by the amount in this parameter. If the SH demand continues through another time period, the set point will be increased again. This will continue until either the SH demand ends, a maximum of 20 increases has occurred, or the maximum set point has been reached. Once the SH demand has been satisfied the set point will revert back to its calculated setting. The boost temperature can be changed by the installer by accessing parameter F8. The temperature range of this parameter is 0°F (0°C) to 45°F (25°C). The default value is 0°F (0°C). This feature will be active if this parameter is set to anything other than 0°F (0°C). Boost time The boost time parameter sets the amount of time that must elapse with a SH demand before the water temperature set point will be increased. This parameter can be changed by the installer by accessing parameter F9. The time range for this parameter is 1 minute to 60 minutes. The default value is 20 minutes. 12 User’s Information Manual 3 SMART SYSTEM control module (continued) Status display screens Status Display Screens By using the Previous/Next (, ) arrow keys on the SMART SYSTEM display panel, you can navigate through the nine (9) display screens.
