There are 6 terminals on the back of the unit and are number 1-6 from left to right. The left most (1 and 2) are the switch terminals. The middle (3 and 4) are the power. The right (5 and 6) are for the thermocouple. Although the terminals are identified on the unit with regular old Arabic numerals the text there is foreign, most likely Chinese, characters.
To hook up the unit I split an extension cord and put the temperature controller in the middle, which the following instructions detail: I purchased a http://amzn.com/B0002J1KRQ and cut it 1/3 of the way down from the female end. The only other parts needed are an extra piece of wire the same gauge as the wire in the extension cord 1.5" long and one wire nut. After cutting the extension cord and I then cut back 1.5 of an inch of the main insulation (on both pieces of the extension cable) exposing the 3 insulated wires per piece of cable. Next I stripped all of the insulators back 1/4 of an inch to exposes the wires (3 per piece of cable and twice on each side of the extra wire). The neutral, white, wires I joined together and mounted into terminal block 4. The male cable's (the one that plugs into the wall) black wire and one end of the extra wire were mounted into terminal block 3. The other end of the extra wire was mounted into terminal block 2. The black wire from the female side of the extension (part the crock or other device plugs into) was mounted into terminal block 1. The green (ground) wires from each side of the cable were connected with a wire nut. The two ends of the thermocouple were mounted into terminals blocks 5 and 6. I looped the ground up over the screw extrusion where the back plate mounts and screwed down the back plate (this holds the ground line up and pins the extension cable up into the back and force the ends of the now pieced back together extension cord out of each end of the temperature controller. (see Ravi's customer image ... it is very close to my assembly).
Note: If you don't have an extra piece of wire just cut 1.5" off of the long side of the extension cable after cutting the cable in half and take the black insulated wire as your extra piece of wire.
See customer images for a picture of my setup.
Most the manual is in very poor broken English, but I found it easily decipherable. That said besides the table, you really don't need it.
Codes (hold set for 3+ seconds to access)
HC - heat/cool - H/C (heat or cool); heat mode turns on switch when temp is too cold (setting - hysteresis). cool mode turn on switch when temp is too hot (setting + hysteresis).
CP - slew or hysteresis - 1-30 degrees F; see above for usage
LA - lowest operating temperature - -58 degrees F; when exceeded the device will switch off the load and blink LLL.
HA - highest operating temperature - 194 degrees F; when exceeded the device will switch off the load and blink HHH.
PU - delayed start - 0-10 minutes; When heat/cool setpoint (- [for heating]/+ [for cooling] the hysteresis) is reached the delay will start counting down and then switch on the connected load. The intent here is to give a minimum off time to a device, e.g. a compressor, which if not given proper time to internally cool from switch on heat inertia will be damaged.
CA - temperature correction - -10-10 degrees F
Set:Hold for 3+ second to access setting menu. Press set to accept and exit settings menu after configuring a parameter.
Rst: In set menu less than 3 second press exits.(3+ seconds when in set menu to reset to factory defaults or 6+ second anywhere else to reset to factory defaults)
UpArrow: Increases settings. When not in setting menu this sets the heat/cool set point. Hold for 2+ seconds to auto advance.
DownArrow: Decreases settings. When not in setting menu this sets the heat/cool set point. Hold for 2+ seconds to auto advance. (From main display of temperature hold for 6+ seconds to lock parameters, including temperature set point, from being changed; hold another 6+ second to release from lock mode).
The light next to Heat or Cool turns on when the load is on.

The controller fits perfectly into a $0.6 plastic electrical box (B122A size), which is available in any home improvement center. I spend less than $3.00 for extra material to build a very nice controller box - see picture.
Many people complained about the poorly written manual for the controller. I would like to share my knowledge about this controller. I hope this Manual will help.
Manual for MH1210F 10A 110V Digital Temperature Contoller with Sensor - NTC 77 Fahrenheit=10K B3435.
Display Codes (Adjustable Parameters):
HC H/C Heating or Cooling mode.
CA -1.5 Temperature Calibration. -1.5 is my setting (default at 0.0 ˚F) which decreases measured temp by 1.5˚F. At the default 0.0 setting, my controller reads 78.5˚F and a good thermometer reads 77˚F; I entered -1.5˚F in CA, now the controller and the good thermometer have the same readings.
PU 00 Delayed cooling start time (minutes). Minimum off time to protect cooling compressor.
HA 194 Highest operating temperature limit (default at 194˚F). When exceeded the device will switch off the load and blink HHH.
LA -58 Lowest operating temperature limit (default at -58˚F). When exceeded the device will switch off the load and blink LLL.
CP 01 Temperature Differential Setting. 01 is my setting (default at 02 or 2˚F). Turn on at 1˚F below temperature setpoint. If my temperature setpoint is 77˚F, heater is turned off when temperature reached 77˚F and turned back on when temperature dropped to 76˚F. The aquarium is always between 76˚F and 77˚F, a 1˚F temperature differential.
Set: Press once to change temperature setpoint. Then press once return to display measured temperature. Hold for 3+ seconds to access parameters setting menu. Press "Set" to accept and exit settings menu after configuring a parameter.
Rst: Press once to exit current setting. Press and hold 6+ second to reset to factory defaults.
UpArrow: Increases settings. When not in parameters setting menu, this sets the heat/cool setpoint. Hold for 2+ seconds to auto advance.
DownArrow: Decreases settings. When not in parameters setting menu this sets the heat/cool setpoint. Hold for 2+ seconds to auto advance.
DownArrow: From main display of measured temperature, hold for 6+ seconds to lock parameters from being changed (display shows "OFF"), temperature setpoint is NOT locked and still can be changed; hold another 6+ second to release from lock mode (display shows "ON").
