WHAT IF…
AUXILIARY HEAT indicator is displayed…
The AUXILIARY HEAT indicator appears on
the heat pump version of the Thermidistat
Control only. It is displayed when your
system is operating on auxiliary heat.
NOTE: This indicator does not reflect a problem
with your system.
CLEAN FILTER indicator is displayed…
The CLEAN FILTER indicator tells you
when to clean or replace your system’s air
filter. Press the VACATION and
HOLD/END buttons simultaneously after
cleaning or replacing the filter to turn off
the indicator and restart the timer.
NOTE: This indicator does not reflect a problem
with your system.
HOLD indicator is displayed…
The HOLD indicator reminds you that
your Thermidistat Control’s comfort
schedule has been overridden. This
function will hold the current temperature
settings indefinitely, so it can be used to
hold an energy-saving temperature setting
for several days if needed. Press the HOLD
button to resume normal system operation.
NOTE: This indicator does not reflect a problem
with your system.
