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.
WARNING
Always turn o󰀨 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.

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.
When using the outdoor sensor and connecting
to the To and Tc outdoor temperature terminal
connections we suggest using a separate 2-wire
thermostat wire cable to the sensor.
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 o󰀨 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 Air Temperature Sensor Installation
(Optional)
The optional outdoor air (temperature) sensor
(OATS) (X2658) wiring distance to iComfort M30
should not exceed 150 feet (45 meters) when
wired with minimum 22 #AWG (recommend 18
#AWG) dedicated 2-conductor thermostat cable.
Installation of OATS must comply with the following
requirements:
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

5
programmable balance points.
• Dew point humidity control
• Humiditrol EDA operation (required)
• Connects to To and Tc terminals 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
a󰀨ected by:
• Drafts or dead spots behind doors and in
corners.
• Building entrances or automatic doors
• Heat generating equipment such as kitchen
equipment
• 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 three 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 a󰀨ect the thermostat’s
internal temperature sensor.
8. Trim 1/4 inch (6 mm) insulation from end of
each thermostat wire lead.

6
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.
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.

Thermostat Terminal Information
Table 1. Terminal Designations
Terminal Purpose
Tc and To
Used for connection to an optional outdoor tem-
perature sensor. Use only dedicated 2-conductor
thermostat wire.
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.
Connect accessory to terminal ACC2 and change
software setting to the applicable type of accessory.
Power is supplied by R2 to ACC1 factory jumper.
NOTE: The ACC1 is intended to be the voltage
input terminal for the ACC relay. If
the ACC relay is congured as a
Dehumidier and Humidier, the ACC1
terminal needs to be jumpered to “R2”
to supply the 24VAC from the HVAC
system’s 24V source. A jumper between
R2 and ACC1 will be shipped installed
by the factory.
NOTE: If the ACC terminal is used for ventilator
devices which have their own voltage
supply and need a set of “dry relay
contacts” then the jumper will need to be
removed from R2-ACC1.
R2
This is the secondary 24VAC power source for ACC
(Accessory). The R2 terminal is connected to the
ACC1 terminal by factory provided jumper.
