K4: 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. To adjust
the System Pump Mode, access parameter K4. The default
mode is CFH.
L: Service Notification
L1: Service calendar 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. This parameter is adjustable by the installer by
accessing parameter L1. The time range for this parameter is 0
months to 36 months. The default time is 12 months.
L2: Service runtime (hours)
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. This parameter is adjustable
by the installer by accessing parameter L2. The time range for
this parameter is 0 hours to 100,000 hours. The default time is
10,000 hours.
L3: Service 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 L3. The range for this
parameter is 0 cycles to 100,000 cycles. The default is 10,000
cycles.
L4: Reset service reminder
Once servicing has been completed, the service notification
counter should be reset. This parameter can be reset by the
installer by accessing parameter L4. Once accessed, press the
RESET key to reset the service notification counter.
L5: 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”. Look behind the control panel at the connector plugged
into X5 on the control board. Note the number written on the
connector. Access parameter L5. That number should appear
after the word “Setting:” on the bottom line. If this number
matches the number on the connector, press “Enter”.
J7: Set point at high voltage
This setting determines the set point 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 Set Point. This parameter can be adjusted by the installer
by accessing parameter J7. The temperature range for this
parameter is 32°F (0°C) - 230°F (110°C) (boilers), 32°F (0°C)
to 190°F (87°C) (water heaters), or 32°F (0°C) to 105°F (40°C)
(pool heaters). The default value is 190°F (88°C) for water
heaters, 220°F (104°C) for boilers, and 105°F (40°C) (pool
heaters).
J8: 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. This parameter may be adjusted by the installer by
accessing parameter J8. The range for this parameter is (J9 +
0.1V) - 10V. The default value is 2V.
J9: Voltage differential 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. This parameter may be
adjusted by the installer by accessing parameter J9. The range
for this parameter is 0V - (J8 - 0.1V). The default value is 1V.
K: Circulation pumps
K1: System pump delay
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. This parameter
is adjustable by the installer by accessing parameter K1. The
time range for this parameter is 1 minute to 40 minutes. The
default time is 30 seconds.
K2: SH pump delay
The SH pump delay parameter sets the length of time the boiler
pump will run after a SH demand has been satisfied. This
parameter is adjustable by the installer by accessing parameter
K2. The time range for this parameter is 1 minute to 40
minutes. The default time is 30 seconds.
K3: 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. This parameter is adjustable
by the installer by accessing parameter K3. The time range for
this parameter is 1 minute to 40 minutes. The default time is
30 seconds.
