Premier2 Owner’s Manual

What if the word TROUBLE is

displayed on the thermostat?

The 

TROUBLE 

display is used to indicate the following

problems:

Continuously on 

TROUBLE 

with backlight for LCD

flashing—the system has shut down due to a protective

device (see resetting the unit section, page 15).   The

auxiliary heat, if installed, will automatically come on if

necessary to keep the home or building comfortable.

Slow flashing 

TROUBLE 

(about 1 flash/second) with

backlight for LCD flashing—the unit is not receiving valid

thermostat signals. Your unit will operate normally during this

time if possible.  Call your WaterFurnace dealer.

Fast flashing 

TROUBLE 

(about 3 flashes/second)—The unit is locked-out due to

insufficient airflow.  Check, clean or replace filter.  Reset the unit (see page 15).  If unit still

does not operate or the 

TROUBLE 

display is still on, call your WaterFurnace dealer.

What if the words CLEAN

FILTER are displayed on the

thermostat?

This indicates that it is time to replace or clean the air

filter in the system.

After a new (or clean) filter is in place, press the

RESET FILTER 

button to reset the timer.

What do I do in case

of a power failure?

Don’t worry.

 Your Premier2 thermostat employs the latest developments in solid-state

electronic technology. One of its unique features is the elimination of the battery required to

maintain your selected set points in the event of a power loss. The thermostat memory is

unaffected by power failures of any duration. When power is restored, the thermostat will

continue operating as if the power had never been interrupted. However, there will be no

heating or cooling during the outage.
