General Description
The CM712 is an advanced environmental monitor and alarm that
monitor’s temperature and humidity wherever it is located. These sen-
sors are referred to as “internal sensors”.
The CM712 can also monitor two additional temperature zones with
optional temperature sensors that can be located up to 200 feet away.
These sensors are referred to as “external sensors”.
Other advanced features include the ability to monitor two door sen-
sors (dry contact inputs) and a water sensor.
The CM712 has a rechargeable battery backup included that allows it
to continue monitoring for up to 10 hours without power. CM712 will
also send a warning text when the battery voltage gets below 5.8VDC.
This setting is not user adjustable.
The CM712 is programmed and notifies you of alarm conditions by
sending and receiving text messages via the cellular network. No
phone land line is required. The CM712 can send alarm condition text
messages to four cell phones.
Additional Features
Configure the CM712 to send a daily status text at the time you spec-
ify.
All program settings can be password protected
Sensors can be named to help identify the cause of the alarm.
Temperature readings can be set to Fahrenheit or Celsius.
You can request the current status at any time.
FCC ID: RI7GE865

Installation
Installation location depends on which features of the CM712 you are
using.
If you are using the internal temperature and humidity sensor,
located the CM712 in the area of interest away from direct
sunlight or air streams.
If you are using the external sensor(s), locate the CM712 con-
venient to power.
Connect any external temperature sensors, door sensors, or water
sensors purchased from www.temperatureguard.com. See wiring
diagram on page 12.
If you are providing your own SIM card
Turn the power off by sliding the power switch to the OFF position.
Remove the power jack.
Remove the four screws holding the cover on.
Insert the SIM card into the SIM slot.
Replace the cover, insert and tight the four screws.
Plug in the power jack.
Turn on the CM712 by sliding the power switch to the ON position.
The CM712 will power up and register itself on the cell network.
The green LED indicates the connection to the cellular network.
Steady blinking means that it is not registered on the net-
work.
Blinking on and then off for 2 seconds means that the
CM712 is registered on the network.
The Yellow LED indicates power and should be on.
The CM712 will now continuously cycle thru the status of all inputs.

Programming with a Cell Phone
Programming can be done with a cell phone or by email. This section only
covers programming with a cell phone.
It is recommended that you add the SIM number to your cell phone’s address
book.
It is recommended that you program the password last.
Programming is accomplished with commands. For example, if you want the
1st alert cell phone number to be 860-555-1212, then you would send a text
message to the phone number of the SIM card. The text would read,
P1:8605551212
See table for complete set of commands. Commands are not case sensitive
except for password programming.
All commands cannot be sent at once in a single text message. It is recom-
mended that it be broken into several different messages. If possible pro-
gramming with email is much easier.
Suggested Text or Email Programming Order (see pg. 14 for examples)
At the minimum:
You must program at least one cell phone number to receive alarm text
messages.
You must program limits for the sensors that you are using. The fac-
tory default limits are very wide and thus may not cause an alarm text
to be sent.

Commands Explained
In bold is the command, example in parenthesis.
♦ Units: (Units:C or Units:F) Unit is shipped in Fahrenheit. There is no
need to use this command if you want degrees displayed in Fahrenheit.
Changing from Fahrenheit to Celsius does not automatically change the
limits. It applies to all sensors, you cannot set one to C and another to F.
♦ P1:-P4: (P1:8605551212) You may program up to four cell phone num-
bers you wish to receive alerts when temperatures go out of limits for the
programmed time delay. Phone numbers must be at least 10 digits. To
delete a phone number send the command with no number. P1: for ex-
ample.
♦ UID: (UID:Mountain Cabin) This command names the monitor. It will be
displayed in the From portion of a text message sent by the monitor.
This is very useful if you have more than one. 10 characters minimum,
16 max!
♦ AU: (AU:85) This example sets the upper limit of the internal tempera-
ture sensor to 85 degrees. If the temperature were to exceed 85 degrees
for more than the programmed time limit, a text message would be sent.
♦ AL: (AL:35) This example sets the lower limit of the internal temperature
sensor to 35 degrees. If the temperature were to drop below 35 degrees
for more than the programmed time limit, a text message would be sent.
♦ AT: (AT:2) This example sets the time delay of the internal temperature
sensor to 2 minutes. This means that once the temperature went out of
range, the monitor would wait 2 minutes before sending text alerts.
♦ AID: (AID:Room Sensor) Sets the name of the internal temperature
sensor to Room Sensor.
♦ HU: (HU:70) This example sets the upper humidity limit of the internal
sensor to 70%.
♦ HL: (HL:0) This example sets the lower humidity limit of the internal sen-
sor to 0%.
♦ HT: (HT:15) This example sets the time delay of the internal humidity
sensor to 15 minutes. This means that once the humidity went out of
range, the monitor would wait 15 minutes before sending text alerts.
♦ HID: (HID:Humidity) This example sets the name of the internal humid-
ity sensor to Humidity.
♦ BU: (BU:30) This example sets the upper limit of the external tempera-
ture sensor 1 to 30 degrees. If the temperature were to exceed 30 de-
grees for more than the programmed time limit, a text message would be
sent.
♦ BL: (BL:-10) This example sets the lower limit of the external tempera-
ture sensor 1 to –10 degrees. If the temperature were to drop below –10
degrees for more than the programmed time limit, a text message would
be sent.
♦ BT: (BT:5) This example sets the time delay of the external temperature
sensor 1 to 5 minutes. This means that once the temperature went out of
range, the monitor would wait 5 minutes before sending text alerts.
♦ BID: (BID:Freezer) This example sets the name of external sensor 1 to

8
Freezer.
♦ CU: (CU:20) This example sets the upper limit of the external tempera-
ture sensor 2 to 20 degrees. If the temperature were to exceed 20 de-
grees for more than the programmed time limit, a text message would be
sent.
♦ CL: (CL:-15) This example sets the lower limit of the external tempera-
ture sensor 2 to –15 degrees. If the temperature were to drop below –15
degrees for more than the programmed time limit, a text message would
be sent.
♦ CT: (CT:10) This example sets the time delay of the external temperature
sensor 2 to 10 minutes. This means that once the temperature went out
of range, the monitor would wait 10 minutes before sending text alerts.
♦ CID: (CID:Refrigerator) This example sets the name of external sensor 2
to Refrigerator.
♦ PT: (PT:1) This example sets the power outage time to 1 minute. Once
power has been out for one minute, a text will be sent. Note: A setting
of PT:0 will only alarm after a power outage of 3 or more seconds.
♦ WT: (WT:1) This example in the table and parenthesis would set the
time delay of the optional water sensor to 1 minute. This means that
once the water sensor became wet a text would be sent one minute later.
♦ RT: (RT:120) This example in the table and parenthesis would set the
reminder time to 2 hours. The monitor will continue to send text alerts
every 2 hours as long as the condition remains in alarm. Zero is the de-
fault and is disabled when set to zero.
♦ ST: (ST:13) This example would send a status message at 1:00 pm
every day. 0 is disabled, therefore you cannot receive a status update at
midnight. Status contains everything the ? Query returns.
♦ D1: (D1:2) This example in the table and parenthesis would set the time
delay of the optional door sensor 1 to 2 minutes. This means that a text
would be sent after the door was open for two minutes. To disable a
doorsensor,setthedelayto999.D1:999 (default)
♦ 1ID: (ID:Front Door) This example sets the 1st door sensor name to
Front Door.
♦ D2: (D2:2) This example in the table and parenthesis would set the time
delay of the optional door sensor 2 to 2 minutes. This means that a text
would be sent after the door was open for two minutes. To disable a
doorsensor,setthedelayto999.D2:999 (default)
♦ 2ID: (2ID:Garage Door) This example sets the 2nd door sensor name to
Garage Door.
♦ PW: (PW:5964) This example in the table and in parenthesis would set
the password of the monitor to 5964. This means that any further texts or
emails sent to the monitor should include on the first line the number
5964. It can be any 4 digits or letters. Letters are case sensitive.
♦ CPW: (CPW:5964) This example in the table and in parenthesis would
clear the password of the monitor which was set to 5964 in the previous
example.

♦ Warning: The commands for PW: and CPW: must be in all caps!
If you forget your password, the only way to clear it is to set the monitor
back to factory defaults. That can only be done by turning the monitor
off, pressing and holding the reset button, while turning it back on. It
can be done remotely, but if it happens on a Friday night tech support
will not be able to help until Monday morning.

Programming with email
The monitor can be programmed with email in the same fashion as a text message with a
few differences.
When sending an email delete your signature line and any other extra characters attached to
a generic email. Remember 160 characters max.
Do not try to program every parameter in a single email. It won’t work. Break it into sev-
eral separate emails. See table on pg. 5.
The subject line must contain the ten digit cellular telephone number you would like the
monitor to respond to.
This example above shows the number of the monitor is 860-555-2424 and the cell phone it
will respond to is 860-555-1212. When this email is sent, the limits of the monitor will be
sent via text to the cell phone. See pg. 12.
