Operation Guide 3M-30

The  3M-30 programmable communicating  

thermostat operates via a high-quality, easy-

to-use touch screen. To program or adjust 

your 3M-30, simply touch your finger firmly to 

the screen. The screen will automatically light 

up and you will hear a “beep.” The screen will 

respond differently to different types of touches, 

so you may want to experiment by touching it 

different ways, finger, fingernail, etc. Do not use 

a sharp or metallic device; it will scratch the 

screen.

ENGLISH

Statement of use:  100% Compatible with all popular 

residential HVAC systems; 24VAC single, two stage

single stage or with auxilliary heat (electric or fossil), 

zoned forced air and zoned hot water (2 or 3 wire), millivolt

SWING

   (HVAC cycling rate)  This feature allows you to set the desired variance in temperature 

between the  3M-30 setting and the room temperature required before the heating or cooling system 

will turn on—from 0.5° to 2.0° F (.25° to 1° C). For example, if SWING is set to 2.0° F and the  3M-

30 is set to 70°F Target Temperature, the heat cycle will start when room temperature drops to 68°F. 

Similarly, the cooling system will start when the room temperature increases to 72°F. The HVAC then 

runs and will shut off at the Target Temperature. 

To set 

SWING:

Touch SWING.

Touch the left/right arrows to set the SWING from 0.5° to 2.0° F.

The HVAC will run more frequently at .5°F and less at 2°F.  Default is 1°F.

Touch HOME to return to the MENU screen.

CALIBRATE

     Your thermostat was accurately calibrated at the factory to ±1° F of actual ambient 

temperature. You do have the option, however, to change the display temperature to match that of a 

previous thermostat, or to match another thermostat already in your home. The range of change is from 

-6°F to +6°F or -3°C to +3°C.

To change your Thermostat Calibration, touch MENU and then touch CALIBRATE.

Use the + / -  to adjust the displayed temperature up or down, as desired. 

The DELTA FACTOR that appears on the screen will also automatically increase or decrease for 

each  0.5° (F or C) adjustment so you can see your change. The large display will show the modified 

temperature reading that will be displayed on the HOME screen and used as the new room temperature.

Press 

HOME to return to the Home screen.

DIFF

 

(Used for 2 stage normal or heat pump with auxillary only, not on screen for single stage).

The differential is the number of degrees between the room temperature and the Target Temperature at 

which the 2nd stage will be used. Default is 2°F.

Touch 

MENU and then DIFF. use the arrows to set the DIFF

Recommend  

DIFF  be set to 2°F for very cold climates and to 4°F for warm climates.

MANUAL Screen Functions

 

The 3M-30 has 4 manual override commands. The manual screen is accessed by touching the large 

current temperature display on the middle of the HOME screen.

IMPORTANT: The Mode must be in HEAT or COOL  to access the manual screen. 

TEMPORARY override   Touch the + / -  arrows to select your desired temporary Target Temperature.  

Touch HOME to return to operation.  The 

TEMPORARY icon will display indicating you have modified 

the Target Temperature for the current Time Slot only. It goes back to the program target at the next 

period. Also once in temporary,  if the target is set the same as the programmed target for that period, 

the word TEMPORARY will go out. 

HOLD  This will hold the target temperature you set indefinitely, until you turn HOLD off.  HOLD will allow 

you to operate your thermostat as a manual thermostat.  It will keep whatever temperature you set until 

you change it or cancel hold. Take care using the 

HOLD function as the program is now bypassed.  To set 

a hold target temperature, touch 

HOLD and use the +/- icons to select your hold temperature. The HOLD 

icon will display on the HOME screen indicating you have changed the Target Temperature.  The system 

will 

HOLD this temperature until you return to the manual screen and de-select HOLD by touching it. Hold 

is also canceled when you set the mode to OFF.

HOLIDAY   This is a single program that repeats day after day until you turn it off. It supersedes the 

weekly program. To use it touch 

HOLIDAY on the temporary screen. The default holiday program is 

shown below. To modify this program, touch the PROGRAM  button and then touch the DAY area until

EMER (in HEAT PUMP type) 

If you setup your 3M-30 for HEAT PUMP with auxiliary heat, EMER function is available with a 

switch under the top cover on the right. If you switch EMER to ON, your heat pump is disabled and 

auxiliary heat is your sole source of heat. This manual override stays active until you switch EMER 

off.   Auxiliary heat is more expensive than the heat pump so use EMER only if the heat pump cannot  

keep up or is defective.

Other  Functions

Save Energy Button

The “Save Energy” feature on the 3M-30 provides a simple, easy-to-use way to help you manage 

your energy use. SAVE ENERGY automatically adjusts your Target Temperature up in COOL or 

down in HEAT by 4

o

F.   To use Save Energy, press  the Save Energy button in the upper left corner 

of the unit. The screen will now read “Save Energy”.   To return to normal operation, press the “Save

FAN Switch

AUTO: The fan control is normally in AUTO mode, meaning that the fan operates automatically with 

the HVAC system and the thermostat. When the fan switch is in 

ON, the fan will run continuously until 

switched back to 

AUTO.

[NOTE: Fan 

ON function is available in the OFF mode to allow simple ventilating.]

Simple Screen 

This display mode limits the amount of information on screen and limits the functions to just the 

+/- arrows. To access the limited display “Simple Sceen”, hold down the PROGRAM button for 12 

seconds.  Hold down the PROGRAM button for 12 seconds to leave the limited display screen. 

RESET button 

The RESET button re-boots the 3M-30 processor. It does not effect the user 

programs that have been stored in permanent memory.

Compressor Protection   

The 3M-30 has a minimum cycle time of 4 minutes to protect your 

compressor in cool and in heat pump (if you have one). The Home screen will show a small clock and 

A/C during this time and the compressor will not come on until the 4 minute delay is over.

Communicating Thermostat

  

The 3M-30 has 2 RTM-1 radio ports. These allow your thermostat 

to communicate with other systems. Depending on your area 

power company, programs may be available to connect your 

thermostat to power grid status information. This can make it easy 

for you to moderate your energy use at peak hours and use power 
when it is less expensive. 

Using USNAP Radios

 - The USNAP ports allow you to 

connect your 3M-30 to your home WiFi network. This can give you 

access to your home’s HVAC system even when you are away 

[with additional web service].  It can also give you access to web 

based efficient energy management sites that can help you save 

money and protect the environment.You can connect your 3M-

30 to an AMI network for In Home Display of electric grid status or connect to a Home Automation 

network for HA functionality with remote access to your HVAC system and home conditions.

 

To Insert a USNAP radio module:

Power off the 3M-30.  Insert the radio module in either 

slot on the back of the 3M-30. Power up 3M-30.

  

To connect to a network follow the instructions that 

came with the USNAP module.

Caution

DO NOT INSERT or REMOVE USNAP radio
