Application:

The ACCUSTAT®                         model ES-H1 thermostat was designed

to operate 24VAC to 30VAC heating systems.  This thermostat is

MERCURY FREE!!  The ACCUSTAT®                           models utilize

pre-set plug-in temperature setpoints to activate the circuits.  Room air

temperature is measured by a microprocessor and compared with the

plug-in setpoint temperature.  The thermostat has a locking cover to

prevent tampering.

Operating Conditions:

The electronic mechanisms incorporated within this unit REQUIRE

operating conditions similar to other electronic devices intended for

INDOOR USE ONLY, such as would be acceptable for TV and similar

household appliances.  Relative humidity must be less than 95% and

the atmosphere must be non-condensing.  Air quality must be main-

tained, FREE of heavy dust or debris which may infiltrate the interior

of this device.  Installation in any space which is unfinished or under-

going repainting or general rehabilitation is also considered product

abuse.  This device should be removed from service during any local

construction activity.

Cleaning:

This device incorporates a high impact styrene enclosure which is

easily cleaned with a dry cloth or vacuum brush.  Occasional soiling

may be cleaned with a soft cloth lightly dampened with water and/or

mild cleaning solution.  IN NO CASE should this device be directly

sprayed with or exposed to free flowing liquids, including water, which

could penetrate its interior.
