Hydrolevel Company HydroStat 3100 - Page 2

HydroStat
®
can be used in two ways.
By installing the control on an existing immersion well,
HydroStat
®
can be used as a universal replacement for
common Aquastat
®
models. Whether it’s a cold start or
a tankless coil boiler, Hydrostat
®
will provide all the
temperature functions of the control being replaced.
Or, install HydroStat
®
on a Hydrolevel Electro-Well
™
(sold separately) to automatically activate the low water
cut-off function. With HydroStat
®
you can add low water cut-off
protection to new or existing installations without the added time and
cost to install a separate control.
䡵
Dial-Type Settings
Allows for quick and easy limit and differential settings.
䡵
Dynamic Temperature Display
This 3-digit LED display continually indicates boiler temperature. Whenever the high limit,
low limit or differential temperature dials are turned, the LED instantly changes to display
the setting temperature. For a quick reference, the LED will scroll through the current
temperature and differential settings each time the HydroStat
®
control is powered up.
䡵
Easy to Wire
HydroStat
®
uses the same terminal designations as common Aquastat
®
models. This makes field replacement
fast and easy.
䡵

®
is powered and the temperature
