Service Notification

Service interval time (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. The time range for this parameter is 0 months
to 36 months. The default time is 12 months.

Service interval run

When the boiler control determines that a scheduled service
is due based on the hours of actual operation, the boiler
display will alternate the standard boiler display text with the
message SERVICE DUE every 5 seconds. The time range for
this parameter is 0 hours to 100,000 hours. The default time is
10,000 hours.

Service interval operation

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. The range for this parameter is
0 cycles to 100,000 cycles. The default is 10,000 cycles.

Reset service reminder

Once servicing has been completed, the service notification
counter should be reset. Once accessed, press the RESET key to
reset the service notification counter.

Accept personality plug

After replacing a control board, the new control will require the
installer to verify the model in which it is installed. As soon as
the power is turned on, the screen will display “Wrong ID Plg”.
Locate the control ID label on the front of the control panel.
Note the number written on this label. Access this parameter.
That number should appear after the word “Setting:” on
the bottom line. If this number matches the number on the
connector, press “Enter”.

Maximum setpoint

This setting determines the setpoint used by the unit or cascade
when the BMS voltage is at or above the Voltage at Maximum
setting. This parameter is only active when the BMS type is set
to Setpoint. The temperature range for this parameter is 32°F
(0°C) - 230°F (110°C) (boilers) or 32°F (0°C) to 190°F (87°C)
(water heaters). The default value is 190°F (88°C) for water
heaters and 220°F (104°C) for boilers.

Voltage to start CFH

When the Enable input is set to Inactive, this parameter
determines the BMS input voltage at which the unit or cascade
is enabled. When the unit is disabled, the unit will become
enabled when the BMS input voltage rises up to or above this
value. The range for this parameter is (Voltage Differential CFH
parameter + 0.1V) - 10V. The default value is 2V.

Voltage differential stop CFH

When the Enable input is set to Inactive, this parameter
determines the BMS input voltage at which the unit or cascade
is disabled. When the unit is enabled, the unit will become
disabled when the BMS input voltage drops down to or
below the enable voltage minus this value. The range for this
parameter is 0V - (Voltage to Start CFH parameter - 0.1V). The
default value is 1V.

Circulation pumps

System pump delay (boiler only)

The system pump delay parameter sets the length of time the
system pump (if connected) will run after a SH demand has
been satisfied or outdoor air shutdown begins. The time range
for this parameter is 1 minute to 40 minutes. The default time
is 30 seconds.

SH pump delay (boiler only)

The SH pump delay parameter sets the length of time the boiler
pump will run after a SH demand has been satisfied. The time
range for this parameter is 1 minute to 40 minutes. The default
time is 30 seconds.

DHW pump delay

The DHW pump delay parameter sets the length of time the
DHW pump (boiler), or unit pump (water heater) will run
after a DHW demand has been satisfied. The time range for
this parameter is 1 minute to 40 minutes. The default time is
30 seconds.

System pump mode (boiler only)

The system pump can be configured to operate in one of two
modes. “CFH” runs the system pump whenever there is a SH
demand. “WWSD” runs the system pump continuously, except
when the boiler is blocked due to outdoor shutdown. The
default mode is CFH.
