THERMOSTATS AIR CONDITIONING
THERMOSTATS AIR CONDITIONING
thermostats are devices designed to
maintain temperature at a particular point in a space or
system. They can be electronic, digital and analog. They
can open or close an electrical circuit depending on
the temperature, keeping it within a set range or level.
• They are designed for measuring or controlling the
temperature
• The simplest types have a bimetallic plate for
opening or closing a circuit which activates or
deactivates a compressor
I. DIGITAL THERMOSTATS
Perfect manufactured thermostats especially designed
for domestic, industrial and commercial applications.
Ideal for (heat or cold) temperature control of conned
spaces.
FEATURES
• Base and re-resistant cover
• One-piece design for easy installation with
convenient wiring
• The most sophisticated models can function at
microprocessor levels
• They have a wide range of applications in domestic,
commercial and industrial refrigeration and AC
systems
• Multiple mounting congurations
• Easy and friendly use
They are highly sensitive and safe, and have a liquid-
display digital thermometer for accurately monitoring
room temperature.
• LCD display for a precise room temperature reading
• System in “OFF” for opening all circuits
• Instant protection against overload and pulse
