Selecting Heating or Cooling
Use the SYSTEM button to select your thermostat system mode. The possible system modes are:
•
•
•
•
•
Heating – Displays on the thermostat as HEAT.
Cooling – Displays on the thermostat as COOL.
Auto-changeover (see below) – Both HEAT and COOL icons are on.
Emergency heat – Displays EMER (flashing) and HEAT.
Off – Displays on the thermostat as OFF.
When heating or cooling is On, STG 1 or STG 1+2 will display (depending on how many speeds your heating/cooling
system is capable of using).
Auto-Changeover Mode
When the thermostat is in auto-changeover mode, it automatically switches between your heating and cooling
programmed schedules to maintain your home temperature within your heating and cooling programs. The thermostat will
call for heating or cooling as needed, but never both at the same time. Auto-changeover is convenient during the fall and
spring when days may be cool in the early morning hours and hot in the afternoons.
Important:
•
•
In auto-changeover mode, the programmed heat setpoint must be 2 degrees lower than the cool setpoint.
Keep the windows in your home closed when auto-changeover mode is in effect, to avoid wasting heating or cooling
energy.

Setting Holds
You can override your heating or cooling program by setting a temporary or permanent hold.
Temporary Holds
A temporary hold is when you override a programmed setting to be in effect until the next programmed time period
begins (Morning, Day, Evening, or Night). You do not have to manually clear a temporary hold. When your next
programmed time period begins, the temporary hold ends and the setting for the next time period is in effect. If desired,
however, you can manually clear the hold at any time.
The thermostat display indicates a temporary hold with a flashing HOLD icon below the Day of the Week.
Permanent Holds
A permanent hold is when you override a programmed setting for an indefinite period of time. A permanent hold lasts
until you manually clear it.
The thermostat display indicates a permanent hold by displaying the HOLD icon below the Day of the Week bar (not
flashing).
Use a permanent hold when you go on vacation or have guests in your home
and want to override your programmed settings for an extended period of
time. Don’t forget to clear it when you come back home or your guests leave.

Critical Event Periods
Critical event periods are periods of time when PowerCentsDC would like you to use less energy. For critical peak pricing
or critical peak rebate customers, a Critical Event period is the same as a critical peak period where you should use less
energy to save money on your electric bill. For hourly pricing customers, it means the hourly energy price is high and you
should use less energy to save money on your electric bill.
To initiate a Critical Event period, PowerCentsDC sends a radio signal to your thermostat to override your settings. Your
thermostat indicates that a Critical Event period is in effect by turning On the green light to the right of the arrow buttons.
The light stays On for the duration of the Critical Event period.
Note: During a Critical Event, you may also see the word “SAVE” appear on the thermostat display.
There will be a limited number of Critical Events each year. For critical peak pricing and critical peak rebate customers,
the hours for Critical Events are:
•
•
June - September 2 pm - 6 pm
November - February - 6 am - 8 am and 6 pm to 8 pm
*Critical Events will not be called in the other months of the year
For hourly pricing customers, the hours may vary. You will be notified about high prices a day in advance.
Note: For critical peak pricing and hourly pricing customers, the price you pay during a Critical Event is substantially
higher than the price at other times. If you override the event, you will use even more high priced energy. Therefore, it is
important to use as little energy as possible during these events. For critical peak rebate customers, you have the potential
to earn a rebate during Critical Events and should try to minimize energy use during an event.

Overriding Critical Events
When you override a Critical Event, the override remains in effect for 8 hours. You cannot cancel an override of a Critical
Event.
Caution: It is recommended that you avoid overriding Critical Events whenever possible.
•
•
For critical peak pricing and hourly pricing customers, when you override a Critical Event, you will pay a
significantly higher energy price for all usage for the duration of the event.
For critical peak rebate customers, when you override a Critical Event, you will miss the chance to earn a significant
rebate for energy saved for the duration of the event.

Displaying Energy Price and Usage Information
For customers on an Hourly or Critical Peak Pricing plan, your thermostat displays information about current energy
price. Customers on a Critical Peak Rebate Pricing plan will see a “0” in the energy price display because your energy
price is the same as on the regular rate plan with Pepco.
Your thermostat displays information on your estimated bill, energy usage, and Critical Event periods for all customers.
During a Critical Event, your air conditioner or heater will be automatically cycled on and off periodically to reduce your
energy use.
Energy Price, Estimated Bill, and Energy Usage Information
For hourly and critical peak pricing customers, your thermostat displays your current energy price in cents/kWh. The
energy price is updated every hour. For critical peak rebate customers, your thermostat will always display a “0” in the
energy price display.
For all customers, your thermostat displays estimated total bill-to-date for the current billing cycle, and accumulated
energy usage in kWh since the start of your current billing cycle. The estimated bill and energy usage are updated once
per day.
When the thermostat is in normal display, the current energy price, estimated bill, and accumulated energy usage display,
alternating with the current period of the day.

The thermostat fan setting may be in the On position. In this position, the fan will
continuously run. Change it to the Auto position.
Thermostat may be currently calling for heat or cool. This is normal operation. Fan
will turn off automatically once the heating/cooling is satisfied if fan is in Auto mode.
With fan in Auto mode and heating and cooling system is not operating, the fan will
not shut off. The air handler fan relay switch is likely bad. Call your heating and
cooling contractor.
•
Heating/Cooling equipment has an internal fan overrun where the fan continues to run
after the heating or cooling unit turns off. Typical fan overrun times are 1-2 minutes
following the heat or cool system shut down.
Fan will not turn On.
Some heating and cooling equipment, especially gas furnaces, have a built-in time delay
before the fan is activated (plenum switch or fan timer). It may take up to 90 seconds. A
temperature sensor in the top of the air handler activates the fan on a gas furnace.
Set the heating setpoint 5 degrees above the room temperature. Wait 5 minutes for the fan
to be activated. If the fan does not activate, call your heating and cooling contractor.
