Adjusting Secondary Set Points
To adjust the secondary set points, press the Day/Night button to
select the secondary (nighttime) mode. The secondary heating and
cooling set points may now be adjusted. (See “How do I set my
thermostat?” on page 6).
Why does my thermostat have an
outdoor button?
Outdoor Button
An optional temperature sensor may be connected to your thermo-
stat. By pressing the OUTDOOR button the current outdoor tempera-
ture will be displayed. If the optional sensor is not connected, the
thermostat will display --.
What are the indicator lights for?
AUX Light
When the AUX light is illuminated, the thermostat is requesting
auxiliary heat. This generally occurs during extreme cold weather
conditions.
FAULT light
The FAULT light is used to indicate the following problems:
Continuously on- system has shut down due to a protective device
(see “Resetting the Unit” on page 12). The auxiliary heat, if installed,
will automatically come on to keep your home comfortable.
Slow flashing (1 flash/sec)- the unit is not receiving valid
thermostat signals (call your independent WaterFurnace dealer). Your
unit will operate normally during this time if possible.
Fast flashing (3 flashes/sec)- system has shut down due to
improper airflow and the entire system (including auxiliary heat) has
been shut off (see “Resetting the Unit” on page 12).
Note: There is an additional indicator light on the thermostat
which is normally not used by the Spectra system.
