Welcome to the world of comfort and energy savings with your new Honeywell T7516A,B,C Energy Management Thermostat brought to you by your energy utility. This thermostat allows up to seven separate days of programming. You can set the thermostat to control the temperature in your home, your water heater, and another appliance (such as a swimming pool pump) according to your personal schedule and preferences. This thermostat keeps you comfortable, and saves you energy.
Besides being programmable, this thermostat contains a communications module that allows your energy utility to communicate with your thermostat so you can take advantage of Residential Service Variable Price (RSVP) Rate.
Residential Service Variable Price (RSVP) Rate. The T7516A,B,C Energy Management Thermo­stat informs you of the energy price in effect at any given time (see Fig. 1). A special feature of this thermostat allows you to program it to automatically adjust your energy use for each price. These prices are: Low (least expensive), Medium, High, and Critical (most expensive). The thermostat also provides you with the ability to operate your electric water heater and another appliance based on the price in effect.

Getting to Know Your Thermostat
The thermostat has a display, a covered 15 key keypad, a covered battery compartment, and an indicator light on the front panel (see Fig. 2). Fig. 2 shows the thermostat, display, and all display segments.
Standard Display
The current room temperature and time are always part of the standard display. Other displayed data includes heating and air conditioning (Heat/Cool) status, day of the week, schedule period, water heater and appliance status, and the RSVP current price (see Fig. 2). The thermostat display automati­cally sequences several displays (see Fig. 3).

Keypad
Lift the front cover to see the keypad. From the keypad, you can operate and program the thermostat. To operate the thermostat, press and release the keys.
NOTE: The thermostat registers all program-
ming inputs immediately and main­tains them until manually changed. Low batteries or power outages do not delete thermostat programming.
Battery Compartment
The battery compartment under the left side of the front panel contains two AA batteries that keep the clock running during a power interrup­tion.
Replacing Thermostat Batteries
IMPORTANT
Install batteries to maintain the time in the event of a power loss. Although the thermostat has a low battery indicator, replace the batteries once every two years to prevent the thermostat from losing the time during a momentary power loss.
NOTE: If the time is ever incorrect, you can
not change it. Your energy utility periodically updates the clock to the correct time.
8
69-1611
As the batteries run low, the thermostat display sequence includes an indication of this. The low battery indication appears one to two months before the batteries run out completely. Replace the batteries as soon as possible after the indication appears.
You need two AA alkaline batteries (not supplied); non-alkaline batteries do not last as long, and can leak, damaging the thermostat or wall surface. To replace the batteries:
1. Use a coin to carefully remove the battery door (see Fig. 4).
2. Follow the directions on the label revealed by removal of the battery door.

Programming Overview
Complete the Personal Programming Charts (Tables 3 through 6) before you program your thermostat.
You can program the thermostat with separate schedules for heat, cool, electric water heater, and one appliance (such as a pool pump). Each device schedule is for seven separate days and up to four periods. For convenience, you can program the seven days individually, or simultaneously in any one of the following groupings: Monday through Sunday, Monday through Friday, or Saturday and Sunday. The four periods are: Morning (MORN), Day (DAY), Evening (EVE), and Night (NIGHT).
User Operations
Present Setting
Press and release the Present Setting key to return to standard display from any other display. The display first switches to show the current settings. After a few seconds the thermostat returns to the standard display.
NOTE: If the heating and cooling are both off,
the display will show Set - -.
CAUTION
Equipment Damage Hazard. Use of sharp fingernails or pencil points can damage the keypad beyond repair.
Use the ball of your finger or a soft pencil eraser when pressing the keys.

price changes to a rate programmed to switch on the Water or Appliance.
Recovery From Setback
Recovery is the time when the thermostat operates the heating or cooling equipment to return the house from the energy savings to the temperature you prefer when you are present and awake.
14
69-1611
This thermostat uses a recovery process that turns your heating/cooling equipment on or off at the time you program the temperature to change. For example, if you set the thermostat to heat to 72°F at 6:00 AM, the heating equipment comes on at 6:00 AM and begins warming the house to 72°F. If you want the temperature in the house to be 72°F at 6:00 AM, you must set the thermostat to turn on earlier; for example, 5:30. (The amount of time required to warm or cool your house to the temperature you want depends on many factors such as the size of your heating/cooling equipment and the outdoor temperature.)
NOTE: If the thermostat is for a heat pump
system, the thermostat uses a method of recovery that helps reduce the use of auxiliary heat.
Programming Your Thermostat
IMPORTANT
Press and release the Present Setting key to exit programming and return to the standard display.
NOTES:
— Energy prices supplied by your
energy utility may influence the times you choose to schedule periods for maximum energy efficiency.
— Each period can occur at any pro-
grammed time; for example, you can set morning at 9 PM. When you program the thermostat, be careful to use the correct time to avoid confu­sion.
15
69-1611
MORN is the time you get up. Generally,
you want the house at a comfortable temperature when you wake up. Set the MORN time earlier than your alarm clock so your home has time to reach the desired temperature.
DAY is the time you leave for work or
school. Generally, once you leave your home, you want the temperature higher or lower (depending on the season) so that you can save energy while you are away.
EVE is the time you return from work or
school. Again, you want your home at a comfortable temperature when you return and go about the normal activities of your evening. Set the EVE time earlier than the time you arrive so your home
has time to reach the desired tempera­ture before you get there.
NIGHT is the time you usually go to sleep.
While you are sleeping, you can save energy by setting the thermostat to control the temperature higher or lower (depending on the season).
If you choose not to program the thermostat, it controls the temperature using the following defaults:
The cooling temperature remains set to a constant 78°F.
At 6:00 AM every day, the thermostat sets the heating temperature to 68°F.
At 10:00 PM every night, the thermostat reduces the heating temperature to 60°F
You do not need to enter a time and tempera-
16
69-1611
ture program for every period if your schedule does not require it; for example, if your home is occupied during the day on weekdays, you can program only the MORN and NIGHT times.
NOTE: You cannot set temperatures higher
than 88°F or lower than 45°F.
As the cost of energy increases, the thermostat uses your pre-programmed choices to reduce usage by temporarily changing the setpoint; that is, it changes the temperature setting— increasing it for cooling, decreasing it for heating—or turns off the water heater and/or appliance.
Price Response
You can also program the thermostat based on the current price of electricity. Use Tables 7 and 8 to plan the Price Response program.
Price Response programming allows the thermostat to respond to changes in the RSVP prices. Your energy utility tells the thermostat what the current RSVP price is for electricity. These prices are: Low (least expensive), Medium, High, and Critical (most expensive).
NOTE: You can enter the number of degrees
you want the thermostat to change the temperature (offsets) for each price except Low. The Low price always uses whatever schedule programming exists and it is the basis for the offsets. The one exception is the water heater, which is always enabled during the low price.
17
69-1611
CAUTION
Equipment Damage Hazard. Use of sharp fingernails or pencil points can damage the keypad beyond repair.
Use the ball of your finger or a soft pencil eraser when pressing the keys.
IMPORTANT
When programming for the appliance, make certain that you consider potential safety issues; for example: with a pool pump during winter freezing weather, you will have to operate the pool pump as you have always done to prevent pump and pipe freezing.
NOTE: Before programming the thermostat,
remove the clear protective plastic display overlay.
Entering Schedule Programming
Refer to your Personal Programming Charts and proceed as follows:
IMPORTANT
The thermostat registers all program­ming inputs immediately and main­tains them until manually changed. Low batteries or power outages do not delete thermostat programming.
18
69-1611
NOTE: When setting a program time or
temperature, the instructions direct you to “Press and hold until the display shows the desired time (or temperature).” This changes the setting quickly in the selected direction. Use this method when the change is large (for example, two hours, or ten degrees). Once the setting is close, press and release the key to move the setting one step at a time.
Inputting Basic Program
The most efficient way to program the thermo­stat is to first input a basic program for the entire week. Then, you can make changes to specific days to fit your needs.
IMPORTANT
Because this procedure can affect up to seven days of programming, be careful when making changes with multiple days selected.
NOTES:
— If you delete all programming with the
CLEAR key, the thermostat uses the default program.
— PGM is an indication that you are in
programming mode.

Programming Price Response
Overview
Price response allows the thermostat to respond to changes in the RSVP prices. Your energy utility tells the thermostat what the current RSVP price is for electricity. These prices are: Low (least expensive), Medium, High, and Critical (most expensive). As the cost of energy increases, the thermostat reduces usage by temporarily changing the setpoint; that is, it changes the temperature setting— increasing it for cooling, decreasing it for heating—or turns off the water heater and/or appliance. If you do not enter any price offsets, the thermostat uses the default settings (see Table 2).

The Low Price Response settings are fixed and cannot be changed.
Heat offsets are always negative (less heat to save energy). Cool offsets are always positive (less cooling to save energy). Hot Water and Appliance settings are simply on or off.
The offset entered is the number of degrees you are willing to allow the heating or cooling
temperature to change from what you pro­grammed for normal operation to save money at each price. Think of the Price Response programming as what you are willing to give up to save money when RSVP prices increase.

With an appliance, the APPL indicator lights with either an ON or an OFF indication. With APPL set to OFF at a particular price, when the price reaches that level, the appliance load turns off, ignoring the program schedule. The water indicator works identically to the appli­ance indicator with one exception: when the RSVP price is low the water indicator is always on.
NOTE: Price Response programming does
not affect temperature, water, or appliance holds.
For example, if you want your home heated to 72° during low rate, but are willing to allow the temperature down as low as 70° during high rate, your heat offset for rate H (high) is -2 (72° -2° = 70°). If you do not enter an offset, the offset remains as shown in Table 2.
If you program an incorrect offset, press and release the Clear key. This changes the offset on the display to zero. The Clear key works for all programmable rates.
Entering Price Response Programming
Price Response programming is very similar to the other programming. One primary difference is that you can program the temperature offsets and water/appliance setting changes from the same display. The same water and appliance setting changes apply for both heating and cooling. Therefore, they need only be set once. Program them from either the heating or the cooling offset display. The following program­ming instructions—both heating and cooling— detail this process.

Controlling Fan
There are two fan settings: AUTO and ON.
To select the fan setting, press the Fan key. Each time you press the key, the fan status changes to the next setting.
With FAN displayed, the fan is on continuously. Use this setting for improved air circulation or during special occasions of short duration.
With nothing displayed, the fan is in AUTO mode (it comes on with the heating or cooling equip­ment, as needed). AUTO is the typical setting. If you have a two-speed fan, it usually runs on high with cooling and on low with heating.
