ComPressor sHort-CyCle ProteCtion

(ComPressor ProteCt)

This thermostat is equipped with automatic

compressor protection to prevent potential damage

due to short cycling or extended power outages.

The non-adjustable short-cycle protection provides

a 5-minute delay between heating or cooling cycles

to prevent the compressor from being damaged.

NOTE: There is an option in advanced settings that

will allow this safety feature to be disabled.

By default it is set to ON. Short Cycle

protection is disabled during testing of the

outdoor unit. It is automatically reset once

the test is completed.

WARNING

Improper installation, adjustment, alteration, ser-

vice or maintenance can cause property damage,

personal injury or loss of life.

Installation and service must be performed

by a licensed professional HVAC installer (or

equivalent) or a service agency.

IMPORTANT

In all applications, the M30 thermostat can only

be used with all residential units and approved

commercial split-system matches, and those

which meet the following installation criteria:

Installation uses 18 gauge thermostat wire or

larger and wire run length DOES NOT EXCEED

300 feet (91 meters).

Load from any thermostat connection is 1 AMP

or less.

WARNING

Always turn off power at the main power source by

switching the circuit breaker to the OFF position

before installing or removing this thermostat.

All wiring must conform to local and national

building and electrical codes and ordinances.

CAUTION

This is a 24VAC low-voltage thermostat. Do not

install on voltages higher than 30VAC.

Do not short (jumper) across terminals on the gas

valve or at the system control to test installation.

This will damage the thermostat and void the

warranty.

Installation Considerations

Before beginning installation, note the type of

equipment, number of stages, and any accessories

being installed. This thermostat is a 24VAC low-

voltage thermostat and requires a common wire to

the thermostat to operate.

• Shut off all power to system components before

installing thermostat.

• Make sure that all wiring conforms to local

and national building and electrical codes and

ordinances.

• Never short (jumper) across terminals on the gas

valve or at the system control to test installation.

This will damage the thermostat and void the

warranty.

• Never install thermostat on outside walls or in

direct sunlight.

Outdoor Temperature Sensor

Installation (Optional)

Install the optional (purchase separately) outdoor

sensor (X2658) on a northern wall of the home,

away from direct sunlight or other heat sources that

may affect its sensitivity.

The sensor is required for:

• Outdoor temperature displays on the home

screen if enabled

• Balance point adjustment and control. The sensor

enables optimal heating equipment operation via

programmable balance points.

• Dew point humidity control

• Humiditrol EDA operation (required)

• Requires 22AWG thermostat wire or larger and

not to exceed 300 feet (91 meters) maximum run.

• Connects to To and Tc terminals on thermostat

Connect outdoor sensor to terminals Tc and To on

thermostat.

NOTE: If alert code 108 appears on the screen,

check your wiring connections to terminals

To and Tc on the thermostat. Check

resistances using the resistance table

provided in the outdoor sensor instruction.

Thermostat Installation

neW installation

The following procedure is for new installation or

installing the M30 to a new location in an existing

home.

1. Unpacked the thermostat and open the case

with a thin-blade screwdriver. Place between

wall base and unit and twist to separate unit

from base.

2. Select a location for the thermostat about 5

feet (1.5 meters) above the oor in an area with

good air circulation at average temperature.

3. Do not install the thermostat where it can be

affected by:

• Drafts or dead spots behind doors and in

corners.

• Building entrances or automatic doors

• Heat generating equipment such as kitchen

equipment

• Enclose environment unless a remote indoor

sensor is used.

• Hot or cold air from ducts.

• Radiant heat from sun or appliances.

• Concealed pipes and chimneys.

• Non-heated (non-cooled) areas such as an

outside wall behind the thermostat.

4. Run thermostat wiring from indoor unit to

location where thermostat will be installed.

5. Drill or make opening through wall for thermostat

wiring 3/4” x 3/4” (19mm x 19mm).

6. Pull about 3 inches (76mm) of thermostat

wire through the opening and removed outer

thermostat wire jacket. This will help in routing

the thermostat wiring to the proper thermostat

terminals.

NOTE: Thermostat wires and outdoor sensor wire

can be run in the same bundle of wires if

needed.

7. Seal the hole in the wall with a suitable material

to prevent drafts from entering the thermostat

case. Not doing so could affect the thermostat’s

internal temperature sensor.

8. Trim 1/4 inch (6 mm) insulation from end of

each thermostat wire lead.

1/4”

rePlaCement installation

Use the following two steps to replace an existing

thermostat.

1. Remove existing thermostat.

2. Note the wire colors and what terminals they are

connected for future reference.

Common installation PraCtiCes

1. Use the provided wall plate as a template on

where to drill the mounting holes.

NOTE: Installation of wall plate is optional. Use

a eld-provided level to allow for proper

alignment.

(Use a level) Align Wall Plate

Use unit wall plate as template to mark desired

mounting nhole locations on wall.

2. Drill 3/16” (5 mm) holes in wall for provided

wall anchors. Insert provided wall anchors into

drilled holes.

3. Remove back plate from main thermostat

assembly using a at-head screw driver.

4. Route thermostat and outdoor temperature

sensor (optional) wiring from wall through

center openings on wall plate (use is optional)

and back plate.

ture sensor.

ACC1 and

ACC2

Default factory software setting for ACC (Accessory)

is off.

Terminal function setting can be changed by going to

settings > advanced settings > terminal settings.

Available settings are off, humidify and dehumidify.

ConneCting tHermostat Wiring

Use “Table 1. Terminal Designations” on page 8

for connecting the thermostat wiring to the back

plate terminals.

If this is a replacement thermostat, connect

to terminals as noted when removing the old

thermostat. If terminals were different on old

thermostat, use “Table 1. Terminal Designations” on

page 8 and wiring diagrams provided in the kit.
