Honeywell T7516A Thermostat User Manual

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 Thermo-

stat 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.

Replacing Thermostat Batteries

IMPORTANT

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.

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: The thermostat registers all program-

ming inputs immediately and main-

tains them until manually changed.

Low batteries or power outages do

not delete thermostat programming.

NOTE: If the time is ever incorrect, you can

not change it. Your energy utility

periodically updates the clock to the

correct time.

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 interrup-

tion.

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:

(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).

NOTE: If the heating and cooling are both off,

the display will show Set - -.

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.

—

Only items being held appear on the

display.

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.)

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 confu-

sion.

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.

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 tempera-

ture 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-

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.

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.

NOTE: You cannot set temperatures higher

than 88°F or lower than 45°F.

Price Response

You can also program the thermostat based on

the current price of electricity. Use Tables 7 and

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.

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).

69-1611

NOTE: Before programming the thermostat,

remove the clear protective plastic

display overlay.

CAUTION

Equipment Damage Hazard.

Use of sharp fingernails or pencil

points can damage the keypad

beyond repair.

Entering Schedule Programming

Refer to your Personal Programming Charts

and proceed as follows:

Use the ball of your finger or a soft

pencil eraser when pressing the keys.

IMPORTANT

The thermostat registers all program-

ming inputs immediately and main-

tains them until manually changed.

Low batteries or power outages do

not delete thermostat programming.

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.

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.

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).

Appliance settings are simply on or off.

The offset entered is the number of degrees

you are willing to allow the heating or cooling

69-1611

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 appli-

ance indicator with one exception: when the

RSVP price is low the water indicator is always

on.

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 program-

ming instructions—both heating and cooling—

detail this process.

NOTE: Price Response programming does

not affect temperature, water, or

appliance holds.

For example, if you want your home heated to

2° 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.

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 equip-

ment, 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.
