The Smart Control™ incorporates multiple features that increase hot water performance and efficiency.
All settings are accessed via the MODE button. To change any setting, simply hold the MODE button
then tap to cycle through the settings as outlined below.
• When power is applied to the unit, the display will show the setpoint temperature (default 120°F).
• Pressing and holding the MODE pushbutton once for 6 seconds will display
then 120°F. This is the water temperature
setpoint. To raise or lower this temperature setpoint, press the
s
or
t
pushbutton. The temperature can be set between 90°F
and 150°F. To shut the unit down, scroll below 90°F until 0°F is displayed. Shutting the unit down is beneficial if the water heater
will not be used for an extended period of time.
WARNING: Temperature settings above 120°F can create a scald hazard.
• Pressing the MODE pushbutton a second time will cause
to be displayed, and releasing the MODE pushbutton will cause 10°F
to be displayed. This is the differential setpoint, a setpoint that determines how many degrees the water temperature is allowed
to drop before the water heater activates. To change between the available 10°F and 5°F settings, press and release the
s
or
t
pushbutton.
• Pressing the MODE pushbutton a third time will cause
to be displayed, and releasing the MODE pushbutton will cause 0°F
to be displayed. This is the post purge setpoint, a setpoint that allows the boiler to be shut off when the actual water temperature
is a certain number of degrees below the setpoint temperature. Since the circulator continues to run, the post purge feature will
remove excess heat from the boiler after the boiler shuts off. To change the post purge setpoint, press and release the
s
or
t
pushbutton to select 0°F, 4°F, or 8°F below setpoint temperature.
NOTE: If the differential is set to 5°F, then the post purge setting
will not be available and will automatically be set to 0°F.
NOTE: When using the BoilerMate
®
on a zone valve application, the post
purge feature will not function.
• Pressing the MODE pushbutton a fourth time will cause Pri to be displayed, and releasing the MODE pushbutton will cause ‘y’
to be displayed. This is called the priority setting, a setting that allows the domestic hot water to reach the setpoint temperature
before spatial heating is allowed to resume. To disable the ‘priority’ feature, press and release the
s
or
t
pushbutton until ‘n’ is
displayed.
• Pressing the MODE pushbutton a fifth time will cause
to be displayed, and releasing the MODE pushbutton will cause ‘41’ to
be displayed. This is the tank volume in gallons. To change this volume, press and release the
s
or
t
pushbutton to select the
proper tank size (26, 41, 60, 80, or 120 gallons).
• Pressing the MODE pushbutton a sixth time will cause
to be displayed, and releasing the MODE pushbutton will cause a
number to be displayed. This is a BTU heat transfer rate estimate in MBH. This is a diagnostic readout and cannot be changed.
•
NOTE: Any changes made to the above settings will take effect after 10 seconds. This will be acknowledged by a display of
. Thereafter, these changes will be the new control settings even in the event of a power outage.
• An approximation of the actual domestic water temperature in the tank can be displayed in °F by pressing the
s
pushbutton.
• One or more error messages will be displayed if abnormal operation occurs, and an audible alarm will sound for most error
messages. The audible alarm can be silenced by pressing the
t
pushbutton. An
message indicates an unplugged or
damaged thermistor (temperature sensor). Check and replace as necessary. An
message appears when the stored water
temperature exceeds 155°F. Contact your service person to correct the problem. An Er3 message indicates that the actual
domestic water temperature did not reach the setpoint temperature after one hour of attempted heating. Contact your service
person to correct the problem. For models equipped with a water sensor, an Er4 message indicates that a water puddle has been
detected. Contact your service person to correct the problem.
Note: Smart Control
™
is to be used for indoor applications only. Do not operate the Smart Control
™
unit outside
of the following ranges:
• Ambient temperature from 38°F to 125°F.
• Relative humidity ranging from 20% to 90% (non-condensing).
• Boiler load rating up to 15A resistive, 1/4hp inductive @120VAC.
• Circulator load rating up to 15A resistive, 1/4hp inductive @120VAC.
• Space heating load rating up to 8A @ 120VAC.
Note: For models equipped with a water sensor, the water sensor should be placed flat on the floor in a low-traffic area. On a regular
basis, verify that the water sensor is functioning properly by placing the orange puck in a water puddle or inserting a coin
between the two electrodes and listening for an audible alarm.
This water sensor should not be the primary means of leak
detection. See water sensor installation page for more details.
Note: If setpoints were being adjusted when a power outage occurred, then recheck all set points after power has been restored.
