Read This Before Installing Thermostat

IMPORTANT

SYSTEM COMPATIBILITY

Read the entire installation section of this Owner’s Manual

thoroughly before you begin to install or operate your

Hunter Thermostat.

Your Thermostat is designed to operate these

24-Volt systems:

■

Multi-stage heat pumps with auxiliary heat

Single-stage heat pumps

2, 3, or 4 wire gas, oil, and electric furnaces and air condition-

ing systems

Remove the Mylar label from the LCD display window.

INSTALLATION

All installation is normally performed at your

thermostat.

This thermostat will not control 120/240 Volt systems or

millivolt systems.

ARMCHAIR PROGRAMMING

You can program your thermostat before installation by in-

COMPRESSOR PROTECTION

serting the batteries and following the instructions starting

The thermostat provides a 3.5 minute delay after shutting off

5the heating or cooling system before it can be restarted.

This feature will prevent damage to your compressor caused

by rapid cycling.

on page 16. This can be done while you relax in your favorite

chair and is a very good way to familiarize yourself with all the

functions of your Hunter Thermostat.

TEMPERATURE RANGE

BATTERY WARNING

Your thermostat can be programmed between 45°F and 95°F

(7°C and 35°C). However, it will display room temperatures

from 15°F to 99°F (-9°C and 37°C). “HI” will be displayed if the

temperature is higher than 99°F (37°C), and “LO” will be dis-

played if the temperature is lower than 15°F (-9°C).

Fresh alkaline batteries will provide over one year of memory

9backup and clock operation. However, when the batteries

become drained, a low battery warning will appear on the dis-

play. When this message occurs, install 2 new AAA batteries. You

have approximately 30 seconds when changing the batteries to

keep thermostat’s clock and program settings.

AUTO RECOVERY

Your thermostat is set from the factory to gradually recover

NOTE: The default system selection at power-on is HEAT.

Batteries are recommended to prevent an undesired sys-

tem change due to a power outage.

the room temperature from an energy saving program to

your comfort program. Therefore, the thermostat may turn your

system on several minutes prior to your programmed time. This

operation is normal, but can be turned off. Refer to the Options

Menu information on pages 16.

OPERATION

This system operates on your system’s 24 Volt power supply.

The supply is monitored by the thermostat, and it will stop

functioning if AC power is lost. (When using backup batteries,

No AC Pwr” will be displayed.) All system controls will remain

“

off until power is restored.

NOTE: The INDIGLO Night-Light will not function when

AC power is lost.

INSTALLATION

What You Need

This thermostat includes two #8 slotted screws and two wall an-

chors for mounting. To install your thermostat, you should have

the following tools and materials.

■

Slotted Screwdriver(s)

Phillips Screwdriver

Hammer

■

Electric drill and 3/16" bit

Two 1.5 V (AA) size alkaline batteries

Remove Old Thermostat

CAUTION: Do not remove any wiring from existing ther-

mostat before reading the instructions carefully. WIRES

MUST BE LABELED PRIOR TO REMOVAL.

TYPICAL HOME THERMOSTATS

Figure 1

■

IMPORTANT! Turn off the power to the furnace at the main

power panel or at the furnace.

■

Remove existing thermostat cover. See Figure 1. Some ther-

mostats will have screws or other locking devices that must

first be removed. Once wall mounting plate is exposed, look

for wires.

Wall Mounting Plate

Thermostat

Cover

If wires are not visible, they may be connected to the back of

the wallplate. Again, look for screws, tabs, etc. Some models

have doors that open to expose wires and mounting screws.

(

See Figure 1).

Wall Mounting Plate

Wire Labeling

■

Each wire coming from the wall to the existing thermostat is

connected to a terminal point on that thermostat. Each of

these terminal points is usually marked with a code letter as

shown in Table A on the next page.

SHOWN IN TABLE A and B ON PAGES 12-13. (For example,

attach the label marked W to the wire that goes to the W or H

terminal on your existing thermostat.) IGNORE THE COLOR OF

THE WIRES since these do not always comply with the standard.

■

The number of wires in your system can be as few as four

■

After labeling wires, disconnect them from the existing ther-

mostat terminals.

Remove existing wallplate. To make sure wires do not fall back

into wall opening, you may want to tape them to the wall.

If hole in wall is larger than necessary for wires, seal this hole

so that no hot or cold air can enter the back of the thermostat

from the wall. This air could cause a false thermostat reading.

(

for single-stage systems), as many as eight, or any number

in between. If you follow the labeling procedures correctly,

you do not have to be concerned about how many wires

there are.

■

IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY

THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS

PROGRAMMING

Programming Introduction

Studies conducted by the Department of Energy estimate that

setting your thermostat back 10°F (6°C) for two 8-hour periods

during winter can reduce your fuel bill by as much as 33%. By

setting your thermostat up 5°F (3°C) for two 8-hour periods dur-

ing summer you can reduce your fuel bill up to 25%.

You can program weekdays as a group, weekends as a group, all

7 days individually or everyday as a group.

The system fan may also be set to run continuously during a pro-

gram time period.

Your Hunter thermostat is pre-programmed to meet the ENERGY

current operating mode will be used for pro-

gramming.

■

Familiarize yourself with Manual Programming, so that you

can easily modify your programs as your comfort needs

change. Follow the steps below to change the program times

and temperatures.

5) After 15 seconds without a key press, the ther-

mostat will return to normal display mode.

Auto Season Changeover

When the System Selection is in AUTO position, the thermostat

will automatically change between Heating and Cooling systems,

depending on your program. We recommend keeping your pro-

grammed heating and cooling temperatures at least 5°F (3°C)

apart to allow the Auto Season Changeover to occur when the

appropriate temperature span has been reached. However, if

your heating and cooling programs set temperatures are close,

there is a built-in program to prevent the thermostat from

changing unnecessarily.

play. “AUTO” will return when these holds are cleared. Auto Sea-

son Changeover will still function in Home Today mode, as this is

a comfort setting.

For example, you may have the following temperatures pro-

grammed at a given time:

Heat Set Temp = 68°F

Cool Set Temp = 78°F

If the room temperature rises above 78°F, then the thermostat

will automatically change to cool mode and turn on the air

conditioner.

Auto Season Changeover is disabled when the thermostat is in

Temporary or Permanent Override, or Vacation Hold, as these

overrides are energy saving settings. While in any of these

modes, “AUTO” will be temporarily removed form the LCD dis-

Likewise, the thermostat will automatically change to heat mode

and turn on heat when the room temperature falls below 68°F.

OPERATION

SPAN Settings

STAGE 1

The Span settings remain the same for both HEAT and COOL.

Your thermostat is set at the factory to cycle at 1°F (0.5°C)

above and below the set temperature in Stage 1. (Span = 2.) This

setting has been designed to provide a comfortable room tem-

perature under most all conditions. However, if you find your sys-

tem cycling too fast or too slow, then the Span can be adjusted

to modify the cycle time. Refer to the Option Menu Stage 1 Span

selection on page 17.

The Span can be changed at any time and is independent of pro-

gram times or temperatures.

When the thermostat is powered on or the Reset key is pressed,

the Span is reset back to setting 2.

Span = 1. This decreases the cycle time by causing your

system to run shorter.

Span = 3. This increases the cycle time by causing your

system to run longer.

Auto Recovery

Hunter’s Auto Recovery feature meets the ENERGY STAR^®guide-

lines for energy efficiency by allowing the heating or cooling sys-

tem to recover gradually from an energy-saving setpoint tem-

perature to a comfort setpoint temperature.

Auto Recovery calculates how early to turn your system back On,

so that the room temperature is already comfortable by the start

of the comfort temperature program period. Auto Recovery

works in both Heat and Cool modes.

Details of Auto Recovery Operation:

■

Auto Recovery can be disabled by selecting “NO” in the Op-

tion Menu. Refer to page 17.

For example, in Heat mode, you could have the following

programs:

■

Auto Recovery will not operate if Permanent hold, Vacation

hold Temporary hold or Home Today is in operation. It will

also not operate if the thermostat resets due to AC power loss

with no backup batteries.

Program #4 (Overnight)

Set Temp = 60°F

Time = 10PM

Program #1 (Morning)

Set Temp = 68°F

Time = 6AM

The room temperature fell to 60°F overnight. Rather than having

the thermostat turning on at 6AM, Auto Recovery would note

the temperature difference between 60°F and 68°F and turn the

Heat on approximately 30 minutes early. Therefore, the room

temperature at 6AM would be about 68°F instead of 60°F.

■ Auto Recovery can be canceled manually if RET CLEAR is

pressed during the recovery process. If a recovery process is

canceled manually then the recovery process will not start

again until the next program period starts (an exception is

that if time or program is changed then the thermostat will

check Auto Recovery conditions immediately).

or manually) then the thermostat will recalculate Auto Recov-

ery again. Setpoint temperature will be changed to the oppo-

site system’s comfort temperature if the recovery entry criteria

are still met. Otherwise, the recovery process will be canceled

and return to program control mode.
