Benefits
Many control parameters can be adjusted
to meet individual needs. This gives high

adapt to any type of application.
Benefits
The room temperature controller can
protect the compressor by limiting the
on/off switching cycle, thereby reducing
wear and tear and increase the lifetime of
the compressor. Simply speaking, we can
set a minimum on/off time via the control
parameters to control the opening and
closing actions if the user adjusts the
setpoint or heating / cooling mode
changeover incorrectly.
