Service 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 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.
Please note that the brackets ([]) denote
screen status.
NOTICE
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.
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.
