Clean Filter
This is a reminder to you to clean or replace your return air filter. Once you have
cleaned or replaced your return air filter, PRESS and HOLD both the MODE and
FAN buttons together for 5 seconds. The LCD will blink, the filter counter will reset
and the text CLEAN FILTER will vanish.
RECO
If the Adaptive Recovery mode is active, the thermostat will pre-warm or pre-cool
your building to ensure your set temperatures are reached by your scheduled
event start time. Whenever the thermostat is performing a pre-warming or
cooling, the word RECO (recovery) will be shown on the LCD.
HOLD
This indicates that the residential program is ON HOLD (inactive) and a permanent
set temperature is being used. This temperature can be changed manually if
desired. Automatic time-based temperature changes are suspended.
FAuLT
This indicates the SMART 2000 has been requested to shut down the heating,
cooling or air conditioning system as a response from an external command.
This request may have come from a sensor fitted to the air conditioning system,
a sensor monitoring supply power, or a multitude of interlocks. This fault would
require a service call to your air conditioning service person.
