Set Point at Minimum Volts

When programmed for BMS control through the 0 - 10V BMS input or through ModBus and the BMS Type is programmed as SETPOINT, the set point represented by the Volts at Minimum parameter is set by the Set Point at Maximum Volts parameter. The minimum value is 32°F (0°C) and the maximum is the Set Point at Maximum Volts setting. The default value is 70°F (21°C).

Set Point at Maximum Volts

When programmed for BMS control through the 0 - 10V BMS input or through ModBus and the BMS Type is programmed as SETPOINT, the set point represented by the Volts at Maximum parameter is set by the Set Point at Maximum Volts parameter. The minimum value is the Set Point at Minimum Volts setting and the maximum is 190°F (88°C). The default value is 180°F (82°C).

On Volts

When programmed for BMS control through the 0 - 10V BMS input or through ModBus and the BMS Thermostat Input is set to INACTIVE, the On Volts parameter determines the 0 - 10V BMS input voltage at which the boiler is enabled. The minimum value is 0.5V and the maximum is 10.0V. The default value is 2.0V.

Off Differential Volts

When programmed for BMS control through the 0 - 10V BMS input or through ModBus and the BMS Thermostat Input is set to INACTIVE, the Off Differential Volts parameter determines how far below the On Volts setting the 0 - 10V BMS input voltage must be in order to disable the boiler. The minimum value is 0.2V and the maximum is the On Volts setting. The default value is 1.0V.

Service Notification in Months

When the boiler control determines that a scheduled service is due based on days of installation, the boiler display will alternate the standard boiler display text with the message SERVICE DUE every 5 seconds. This parameter is adjustable by the installer by accessing the Service Notification in Months parameter. The time range for this parameter is 0 months to 100 months. The default time is 12 months.

This feature has been disabled by the manufacturer. To enable this feature change parameter K1 to the desired time range.

Service Notification Running Time

When the boiler control determines that a scheduled service is due based on the hours of actual operation, the boiler display will turn yellow and a new status screen will appear informing the installer that maintenance is required. This parameter is adjustable by the installer by accessing the Service Notification Running Time parameter. The time range for this parameter is 0 hours to 17,500 hours. The default time is 8,760 hours.

Service Notification Cycles

When the boiler control determines that a scheduled service is due based on the number of boiler cycles, the boiler display will alternate the standard boiler display text with the message SERVICE DUE every 5 seconds. This parameter is adjustable by the installer by accessing the Service Notification Cycles parameter. The range for this parameter is 0 cycles to 100,000 cycles. The default is 50,000 cycles.

Reset Maintenance Reminder

Once servicing has been completed, the service notification counter should be reset. This parameter can be reset by the installer by accessing the Reset Maintenance Reminder parameter. Once accessed, press the RESET key to reset the service notification counter.

When a Maintenance Reminder timer or counter has expired, a Maintenance Reminder screen will appear on the display. By programming the installer’s name and phone number, this information will appear on the Maintenance Reminder Screen at that time. This can be programmed by accessing the Service Name and Phone Number parameter. When selected, another menu will appear with PHONE and NAME.

1.Rotate the NAVIGATION dial to point to the name/phone number to program and press the NAVIGATION dial. The screen will now display the selected item (either PHONE or NAME).

2.Press the NAVIGATION dial again. A cursor will appear at the bottom of the screen. By rotating the NAVIGATION dial, various numbers and characters will appear. When the desired number/character is found, press the NAVIGATION dial. The cursor will move to the next position.

3.Repeat this procedure until the entire message is entered. If you make a mistake and wish to back up

one character, rotate the NAVIGATION dial until the back arrow (→) character is displayed and press the NAVIGATION dial.

4.When finished, press the RIGHT SELECT [SAVE] key to return to the previous menu.
