Overriding a Utility Curtailment
The thermostat allows your local utility to remotely adjust (curtail) the operation
and temperature of your air conditioning or heating system for short periods of
time - only when absolutely necessary, to help minimize the load on the electric
system during periods of peak usage in your area. You always have the ability
to override (cancel) the adjustment if needed.
If a utility curtailment is active, the words saving mode will be displayed,
indicating you are helping to save energy. The clock display will show the time
remaining in the curtailment.

22 22
Using Emergency Heat
Using Emergency Heat:
Emergency heat is useful when the automatic auxiliary heat system can't keep
up with demand. (Systems with heat pumps use "auxiliary heat" when it's too
cold outside for the heat pump to heat the house without help. The thermostat
display indicator for this is auxiliary heat on.)
If the heat pump compressor that works with auxiliary heat fails, or if the heat
pump isn't working at all, you can turn on the emergency heat for that extra
help. (You'll know there's a problem if the house can't seem to get warm when
it's very cold outside.) You want to avoid using emergency heat, though,
because it's the most expensive option. And, of course, if you suspect a
problem with your heat pump, call for service immediately.
Here's how to set your thermostat to use emergency heat.
1. Open the thermostat door.
2. Press and release the mode button repeatedly until the arrow under the
button moves to Em heat on the screen.
3. Close the thermostat door.

Real-time pricing
Your utility may offer real-time pricing, which is an electric rate pricing strategy
where rates vary over short time intervals, typically hourly. You, as a consumer, can benefit from real-time pricing if you are able to shift or reduce your
electric consumption during high cost periods. Your thermostat will help you do
this by notifying you when real-time pricing is in effect and automatically
adjusting your temperature setpoint by a user-selected number of degrees.
Your utility will provide you with details regarding the pricing associated with
the different pricing periods. During the different real-time pricing periods your
thermostat will display the words energy price med $$, energy price high $$$,
or peak energy price $$$$.
In addition to displaying the real-time pricing notification, the thermostat will also
automatically adjust the temperature setting of your air conditioning or heating
system in accordance with any "offsets" (setpoint adjustments) that you
program into the thermostat, as described in the section which follows. When a
real-time pricing setpoint adjustment is in effect, the words saving mode will be
displayed, in addition to the real-time pricing notification message. If this is
critical peak price, the word critical will also be displayed. In addition, the clock
display will show the time remaining in the pricing event, if that is known.
If you are uncomfortable during a real-time pricing event you always have the
power to override (cancel) the setpoint adjustment.
30 30
Real-time pricing
To override/cancel temperature setpoint adjustment during a realtime pricing event:
1. Open the thermostat door.
2. Press the soft button below override. The words saving mode or
critical saving mode will disappear. The thermostat temperature setpoint
will return to your previous user-programmed value.
3. Close the door. The clock display will indicate the current time of day.
Note that the screen will continue to display the words energy price med
$$, energy price high $$$, or peak energy price $$$$. This indicates that
real-time pricing rates are still in effect (but keep in mind that because you
pressed the override button in Step 2 above, your setpoint is not being
adjusted). You could manually adjust your setpoint again, if desired.
To setup real-time pricing setpoint temperature offsets:
During real-time pricing events you retain ultimate control over your comfort as
you, the consumer, select the number of degrees that you want your temperature setting to be adjusted (0 to 10) based on the type of pricing signal received
(medium, high, critical).
31
Real-time pricing
1. Open the thermostat door.
2. Press and simultaneously hold the soft buttons below the heat and
cool setpoints (the two bottom buttons on the right) until the screen
displays the check filter reset reminder and 01 in the lower right corner.
3. Press the up arrow button until 01 changes to 09 with 1 next to it. You
will also see the words energy price med on the screen.
4. Press the rightmost lower button then press the up or down arrow
button until the screen displays the number of degrees (0 to 10) that you
want to automatically adjust your thermostat's programmed setpoint when
your utility issues a pricing signal.
5. Press the done button.
6. Close the thermostat door.
To setup temperature offsets for periods when your utility issues a high or
peak pricing signal, follow Steps 1 to 6 above, but in Step 3 press the up
arrow button until 01 changes to 10 (for high) or 11 (for peak). You will see
the words energy price high or peak energy price on the screen.
32 32
Time-of-use/peak pricing
Your utility may offer time-of-use pricing, which is an electric rate pricing
strategy where rates vary dependent on utility-designated peak and non-peak
time of day. Your utility will provide you with pricing details. You, as a consumer, can benefit from time-of-use/peak pricing if you are able to shift or
reduce your electric consumption during peak price periods. Your thermostat
will help you do this by notifying you when time-of-use/peak pricing is in effect
and automatically adjusting your temperature setpoint by a user-selected
number of degrees.
During peak pricing periods (which are determined by your utility) your
thermostat will display the words peak energy price $$$$.
In addition to displaying the peak pricing notification, the thermostat will also
automatically adjust the temperature setting of your air conditioning or heating
system in accordance with any "offsets" (setpoint adjustments) that you
program into the thermostat. When a peak pricing setpoint adjustment is in
effect, the words saving mode will be displayed, in addition to the peak energy
price $$$$ notification message.
If you are uncomfortable during a peak pricing event you always have the
power to override (cancel) the setpoint adjustment. See the instructions which
follow.

$$$$. This indicates that peak pricing rates are still in effect (but keep in
mind that because you pressed the override button in Step 2 above, your
setpoint is not being adjusted).You could manually adjust your setpoint
again, if desired.
During peak pricing events you retain ultimate control over your comfort as you,
the consumer, select the number of degrees that you want your temperature
setting to be adjusted (0 to 10)

Smart recovery, Troubleshooting
Smart Recovery:
The Smart Recovery feature transitions your home from one temperature
period (wake, day, evening, sleep) to the next so that the your home's
temperature matches the temperature setpoint at the start of each time
period. This means, for example, that if your sleep period temperature
setting is lower than the period that precedes it, the thermostat will start
cooling down the home before the beginning of the scheduled sleep
period. The thermostat does this at an energy-efficient rate. This not only helps
make your home as comfortable as possible, it also makes your thermostat
usage more cost effective.

the house without help, so it's getting help from the electric heaters. This
happens automatically.
•
Em heat is displayed (heat pump and Hybrid Heat systems only):
Em heat is the display term for emergency heat and applies only to the
heat pump systems. When emergency heat has been turned on, Em heat

is displayed. You have to turn on emergency heat manually - it doesn't
happen automatically - so if you see Em heat on the display, it means
someone has turned it on.
•
There is a Power Outage:

settings are retained in memory.
•
A service reminder message is displayed:
The check filter service reminder message tells you that it's time to change
the furnace filter. Make the indicated changes and reset/remove the
reminder rmessage by pressing and holding the done button for about
three seconds.
