Standard Application
Hydrolevels Fuel Smart HydroStats are installed primarily on residential oil or
gas fired water boilers. Fuel Smart HydroStat combines the functions of
temperature limit control, low water cut-off and energy saving boiler reset into
a single control.
Operation
How Thermal Pre-Purge Works
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.
Thermal Targeting Technology analyzes thermostat activity and continually
evaluates 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 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, the Fuel Smart
HydroStat will lower the boilers Target temperature - saving fuel - while
continuing to provide comfort to the house.
How Thermal Targeting Works
When installed with Hydrolevels ElectroWell, Fuel Smart HydroStat will provide
automatic reset Low Water Cut-Off functionality to any boiler installation. When
the Fuel Smart HydroStat is installed on an electrowell a green LWCO active
light will automatically illuminate on the control.
