You  have  a  power  outage...
An  internal  power  source  maintains  the
desired  temperature  settings
indefinitely.
You  have  a  system  error  message...
The  temperature  sensor  failure
indicator  sends  a --reading  to  the  LCD

temperature  sensor  is  no  longer  able  to
measure  temperatures.  You  will  need  to
contact  your  dealer  to  repair  the
problem.
An  E2 reading  on  the  LCD  display
means  there  is  not  enough  voltage  for
the  system  to  operate.  Contact  your
dealer  for  further  information.
A  flashing  E3 (alternating  with  room
temperature)  indicates  the  outdoor  air
temperature  sensor  is absent  or  not

proper  operation).
If  the  outdoor  air  temperature  sensor  is
absent,  the  outdoor  temperature
reading  will  be  --.
