speed fan
• Fan Purge – Fan remains on for
60 seconds after Heat/Cool call is
dropped for improved efciency (Auto
mode only)
• Room air sampling: Selectable time
intervals ensure the fan will cycle
on periodically, in Auto Fan Mode
to help eliminate room temperature
stratication.
• Selectable Fahrenheit (°F) or Cesius
(°C) temperature scale.
• Dry mode – Operates cooling and
electric heat simultaneously to remove
humidity. Optional electric heat must
be selected.
• Anti-Short Cycle Compressor Pro-
tection.
• Minimum on time for heating and
cooling Helps eliminate room temper-
ature drop and system short cycling.
• Freeze Protection – Prevents evapo-
rator freeze up
.
• Test operation – Allows ease of test-
ing after installation (all timers are
eliminated).
• Non-volatile back-up memory will
maintain control settings for an indenite
