Installer Name and Phone Number
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 parameter K5. 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, select the back arrow (←) character and
press the NAVIGATION dial.
4. When finished, press the RIGHT SELECT [SAVE] key
to return to the previous menu.
Please note that the brackets ([]) denote
screen status.
NOTICE
K: Service Notification
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 parameter K1. The time range for this parameter is 0
months to 36 months. The default time is 0 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 parameter K2. The time
range for this parameter is 0 hours to 100,000 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
parameter K3. 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 parameter K4. Once accessed, press
the RESET key to reset the service notification counter.
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 (J2) is set by parameter J6. The minimum value is
32°F (0°C) and the maximum is the Set Point at Maximum Volts
setting J7. 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 (J4) is set by parameter J7. The minimum value is the
Set Point at Minimum Volts setting J6 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, parameter J8 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, parameter J9 determines how far below the On
Volts setting J8 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 J8. The default value is 1.0V.
