SETTING THE HIGH LIMIT
The high limit is factory set at 190°F. To adjust, turn the HI LIMIT
Dial A to the desired setting. (Setting range: 100°-220°F)
SETTING THE ECONOMY FEATURE
The Economy Feature is factory set for a 1 zone heating system.
To adjust, turn the ECONOMY Dial B until the number displayed
equals the number of heating zones. Do not include indirect
water heaters in the number of heating zones. The Economy
Feature conserves fuel by reducing boiler temperature (see “How
Thermal Targeting Works” below). If the heating system is unable
to supply needed heat to the house, the ECONOMY Dial should
be turned to a lower setting (example: In a three zone house, turn
the dial to 2 or 1). Conversely, if the boiler provides adequate
heat, added fuel savings can be achieved by selecting a higher
setting (example: 4 or 5).
DIFFERENTIALS
Differentials are automatic and will vary based on control settings
and boiler temperature.
ACTIVATING THERMAL PRE-PURGE (OPTIONAL)
Fuel Smart HydroStat has a Thermal Pre-Purge feature to
maximize efficiency. When active, the control will purge higher
boiler temperatures down to 135° at the start of any thermostat
call and supply the latent energy in the boiler to the heating zone
that is calling. During the purge cycle, the PURGE LED will light.
If the heat is not sufficient to satisfy the thermostat, the control will
energize the burner. This feature works with single-zone and
multi-zone heating systems utilizing circulators or zone valves. No
change in wiring is needed.
To Activate Thermal Pre-Purge
Push and hold the LWCO TEST button for 10 seconds. The PURGE
LED will will blink twice and remain on as long as your finger is on the
button. To deactivate the feature, push and hold the button a second
time for 10 seconds. The PURGE LED will blink twice and turn off.
SETTING THE CONTROL
At initial start up, with the Economy Feature active, the control
establishes a 145°F target temperature. To test the high limit
shut-off function, the Economy Dial must be turned to OFF.
Once tested, restore the Economy setting. If the heating
demand is high, the target will increase over time to satisfy the
heat load. NOTE: To reduce the potential for condensing, the
control will allow the boiler to heat to 120°F prior to energizing
the circulator.
Thermal Targeting technology analyzes thermostat activity and
continually evaluate how much heat the house requires. When
it is very cold outside, the heat demand is high and the Fuel
Smart HydroStat will raise the boilerʼs Target temperature to
provide needed heat to the home. When the outside tempera-
ture is milder, the heat demand is lower. During these periods,
the Fuel Smart HydroStat will lower the boilerʼs Target temper-
ature – saving fuel – while continuing to provide comfort to the
house.

SETTING
OFF Disables economy function. Will allow boiler to fire until hi
limit temp is reached and re-fire with a 10° subtractive
differential.
LO Provides lowest level of fuel savings. Use this setting only
if the house does not stay warm at higher settings.

2 Recommended setting for Two zone systems
3 Recommended setting for Three zone systems
4 Recommended setting for Four zone systems

IMPORTANT NOTICE
This boiler is equipped with a feature that saves energy by reducing the boiler water
temperature as the heating load decreases. This feature is equipped with an over-
ride which is provided primarily to permit the use of an external energy manage-
ment system that serves the same function. THIS OVERRIDE MUST NOT BE
USED UNLESS AT LEAST ONE OF THE FOLLOWING CONDITIONS IS TRUE:
• An external energy management system is installed that reduces the boiler water
temperature as the heating load decreases.
•This boiler is not used for any space heating.
•This boiler has an input of 300,000 BTU/hr or greater
• This boiler is part of a modular or multiple boiler system having a total input of
300,000 BTU/hr or greater.
• This boiler is equipped with a tankless coil.
