model ES-H2 thermostat was designed
to operate 24VAC to 30VAC heating systems. The control can be easily
placed in economy mode by simply sliding a switch. 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.

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.
