Product Overview

How Fuel Smart
HydroStat
®
Saves Fuel
Thermal Targeting
The boiler and radiation installed in a house is designed to keep the
house warm on the coldest day of the year. For every other day, the
heating system is essentially larger than it needs to be. With conventional
boiler controls, this “oversized” boiler burns more fuel than is needed to
keep the house warm. Fuel Smart HydroStat
®
uses Thermal Targeting technology to analyze thermostat
activity and continually evaluate how much heat the house requires. When it’s very cold outside, the heat
demand is high and Fuel Smart HydroStat
®
will raise the boiler’s Target temperature to provide needed heat
to the home. When the outside temperature is milder, the heat demand is lower. During these periods, Fuel
Smart HydroStat
®
will lower the boiler’s Target temperature – saving fuel – while continuing to provide
comfort to the home.
Thermal Pre-Purge
To further enhance fuel efficiency, Fuel Smart HydroStat
®
is also equipped with a Thermal Pre-Purge feature.
When activated, the control will purge standing heat in the boiler at the start of any thermostat call, supplying
the “free” latent energy to the heating zone that is calling. If this latent heat is not sufficient to satisfy the
thermostat, the control will then energize the burner. This feature works with single and multi-zone heating
systems utilizing circulators or zone valves and requires no change in wiring.
Electro-Wells are available
in a variety of sizes to fit
virtually any boiler
To enable HydroStat’s low water
cut-off function, Electro-Wells are
available in eight sizes to replace
standard immersion wells.
Machined
Identification Groove.
Distinguishes Electro-
Well
™
from standard
immersion well without
the need to remove
from boiler.
Copper Immersion
Tube. Strong and
proven, it provides
more conductive
surface area than any
other probe-type low
water cut-off.
Electrical Insulator.
Made from special
high temperature
resin, it’s the key to
Fuel Smart Hydro-
Stat’s low water cut-
off capability.
Reverse
Compatible
Mounting Method. Industry
standard immersion well at-
tachment method allows
HydroStat
®
to be mounted on
an Electro-Well
™
or standard
immersion well. Conversely,
virtually any Aquastat
®
can be
mounted on the Electro-Well.
Great for tackling no heat
calls no matter what control
you have.
Available in ½"
and ¾" NPT
