Caution
• Your thermostat is a precise instrument, handle it with care.
• Turn off electricity to the HVAC system before installing or
servicing thermostat or any part of the system.
• Do not turn electricity back on until work is completed.
• Do not short (jumper) across electric terminals at the control
on the furnace or air conditioner to test the system. This may
damage the thermostat.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 3AA alkaline batteries
and/or 24 volt AC C wire (or a 12-24 AC or DC source) and
millivolt gas systems. Each thermostat relay load should be
limited to 1.0 amp; higher amperage may cause damage to the
thermostat.
Caution
To avoid electrical shock and
to prevent damage to the furnace, air conditioner, and
thermostat, disconnect the power supply before
beginning work. This can be done at the circuit breaker.

TOOLS
You will need a small Phillips screwdriver and a drill with 3/16-in. (4.8mm) bit for wall mounts.
LOCATION
Replacement installations - mount the 3M-30 in place of the old thermostat.
A new location will require moving your wiring.
For new installations and for relocating the 3M-30 - follow the guidelines listed below:
• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the oor, and in a room that
is used often.
• Do not install it where there are unusual heating conditions, such as: in direct sunlight; near
a lamp, radio, television, radiator register, replace; near hot water pipes in a wall; or near a
stove on the other side of a wall.
• Do not locate in unusual cooling conditions, such as: on a wall
separating an unheated room; or in a draft from a stairwell, door,
or window.
• Do not locate in a damp area. This can lead to corrosion that will
shorten thermostat life.
• Do not locate where air circulation is poor, such as: in a corner, an
alcove; behind an open door.
• Do not install the 3M-30 until all construction and painting has
been completed.
• This thermostat does not require leveling.

REMOVE OLD UNIT
Switch OFF electricity to the HEATING and COOLING systems.
Then follow these steps:
• Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking
screws on the side or front. These must be loosened. DO NOT remove wires. Note the letters
printed near the terminals. Attach labels (enclosed) to each wire for identication.
Caution
Read instructions carefully before removing any wiring from
existing thermostat. Wires must be labeled before they are
removed. THERE IS NO STANDARD COLOR CODE. When remov-
ing wires from their terminals, ignore the color of the wires and
LABEL THEM by the lettered terminal where they were screwed.
• Label the wires one at a time. You must label all the wires
before you proceed.
• With all wires labeled, remove them from the old unit.
• Make sure the wires do not fall back inside the wall. You can
wind them around a pencil to keep them from falling.
• Loosen all screws on the old thermostat and remove it from the
wall.

What wires do you have? Make sure your wires are labeled. This may require you to
nd the ‘other end’ connection for each wire on your heating or air conditioning equipment and read
the label there. Refer to the Wire Reference page at end of install section for better understanding of
wire labels from different HVAC system makers.
IMPORTANT: The 3M-30 runs on 3 AA alkaline batteries and/or the C wire if available. If you do
not have a C wire you can run a new wire from the HVAC or use a standard 12-24V [AC or DC] wall
transformer. A constant power source is required when using a radio module.
IMPORTANT: If you have both RH and RC you need to
remove the jumper wire between these 2 terminals.
Prepare Wires
Please follow these guidelines for safe and
secure wire connections:
• You will need at least 2.6” of wire for each of your connections to the 3M-30.
• If you do not have enough wire, splice additional wire to allow enough slack
• Terminals accept wires from 16-22awg.
• Fan out wires below the hole as shown.
• Remove insulation 1/8” from the tip of each wire.
• Take care not to damage the labels for each wire in handling.

Find the step-by-step diagram for your system
• Select the referenece
page with your wiring
diagram and set-up
information below.
• The C-wire is optional
but prefered for all
installations [shown dotted
in diagrams]. Some radio
modules will require the
24VAC C-wire power.
• If your combination of
wires is not above you
can use the wiring table
at the end if the install
section to determine your
connections, contact

• “Fan” wires out as illustrated with 3M-30 below the wall opening.
As in the example: fan out the wires so that the C wire is above the C
terminal, the W above the W. This allows the 3M-30 to t snug to
the wall.
Caution
Do not allow wires to touch each other or parts on thermostat.
• Wires will position behind the 3M-30 and up over the
terminal area.
• Do not bunch wires behind the 3M-30. Feed any slack
back into the wall opening.
Connect Your Wires
• Connect labeled wires only to a terminal with the same letter label.
• Insert the wire in the terminal well and tighten the screw securely.
NOTE: If you wish you can mount the 3M-30 to the wall rst, and then connect the wires.
• The 3M-30 can be externally powered with a power source rated from 12V to 24V, AC or DC, at
300ma or greater. If used, connect to the C and RH terminals (no polarity).

HVAC Selection
• Set the HVAC TYPE switch in the NORM position if you have
conventional natural gas, propane, oil, or electric heat. If you
have a HEAT PUMP system set the HVAC TYPE switch to HP.
• Set the HEAT SOURCE switch in the GAS position if you have normal gas or oil heat or if you have
a heat pump with gas or oil auxiliary heat. Put the HEAT SOURCE in the ELEC position if you have
normal electric heat or if you have a heat pump with electric auxiliary heat.
Install 3 AA Batteries
• Install 3 AA alkaline batteries [required] following
the marked polarity in the battery compartment.
Put the lower battery in negative end rst against
the spring, then push the positive end in. Then
insert the last 2 batteries as shown.
IMPORTANT: Press the RESET button (under
top cover) to implement the HVAC switch selections.
• With all the wires connected it is time to turn the AC power back on. Do this at the breaker you used
to switch it off. The 3M-30 will power-up in the control OFF mode. Your 3M-30 is not congured to
operate your HVAC system yet. You must now congure your thermostat for your HVAC system.

Caution
Special Battery Warning
Always replace the batteries as soon as the “Low Batt” ashes. The thermostat is a battery powered
device, you must be responsible to replace batteries before they run out. Failure to replace batteries can
result in overheating or excessive cooling of your house.
• Even if the “Low Batt” indicator does not ash, you should always replace the batteries at least once a
year. Replacing the batteries also helps to prevent leakage that can corrode and damage the thermostat.
• If you are leaving your home for a month or more, you should replace the batteries as a precaution
against battery failure in your absence.
• Always use new alkaline batteries.
• Failing to replace the batteries, when necessary, could cause the thermostat to lose power or
malfunction. If the thermostat loses power, then the thermostat will not control the temperature which
could result in your HVAC system not functioning as you intended and lead to possible damage from
overheating or excessive cooling.
• If the thermostat batteries fail with the heat OFF, this can result in NO HEAT and possible frozen or
broken pipes and water damage.
• If the thermostat batteries fail with the cool OFF, this can result in NO COOL and could cause possible
damage or excessive temperatures.

HVAC Setup on Screen
IMPORTANT: Make sure the 3M-30 is powered up and the
mode switch is set to OFF. HVAC conguration switches must
be set rst [pg 8].
• With mode in OFF press MENU to do HVAC SET UP.
• Use +/- icons to select HVAC SET UP number on screen.
The LCD display will show your selection and indicate the
number of stages you have selected. During setup, 2nd stage
will blink when both heat and cool have 2nd stages.
If you have a Normal HVAC system and
you want fast temperature recovery...
HEAT and COOL select 1
2 stage HEAT, 1 stage COOL select 2
2 stage HEAT, 2 stage COOL select 3
If you want efcient [but slower] recovery...
2 stage HEAT, 1 stage COOL select 4
2 stage HEAT, 2 stage COOL select 5
NOTE: For 2 stage systems your 3M-30 can recover from a temperature setback in 2 ways: 1] Fast Recovery - This uses your 2nd
stage to bring the house to Target Temperature. This may use slightly more energy. 2] Efcient Recovery -This uses the 2nd stage to
bring your house to within a few degrees of the Target and then uses the 1st stage to go the last bit. (See setting the differential in the
operating guide). This is more efcient.
