“CONTROL CUBE T” TEMPERATURE CONTROLLER MANUAL
Important Safety Precautions:
The Control Cube T operates on 110vac, 50/60Hz and can control appliance current of up
to 13A. The controller enclosure is not sealed and under no circumstances should be
immersed in water, installed exposed to weather. There are no user serviceable parts inside
the enclosure, and opening the enclosure will void warranty (section 4) and risk electrical
shock. For in-warranty service or replacement contact info@Perfect-Cheese.com.
Quick look
The Control Cube T is a compact modular digital thermostatic controller that can
be used to control temperature within cooling enclosures like refrigerators or
freezers, or heating liquids using table-top appliances like slow cookers or
electric griddles. The controller requires the appliance have a 110vac power
cord, and maximum continuous current requirement of 13A.

Installation
Note: A video installation tutorial is available at www.perfect-cheese.com.
1. Remove all parts from packaging; check that you have all components
listed above.
2. Determine best location and best mounting option (shelf or wall mount).

3. If you’re wall mounting the CCT remove the mounting bracket and screws.
Locate bracket and mark and drill pilot holes. Attach the bracket to the
wall using the screws (with anchors if you’re attaching to drywall or thin
paneling).
4. Once the bracket is attached you can mount the Cube and plug in to a wall
socket.
5. If the sensor is not attached the display will read “EEE”. Once you plug in
the temperature sensor it should read the correct temperature
6. The cable can be taped in place around the edge of the door
7. If you want to permanently install the sensor (a) drill a 3/16” diameter or
larger hole into the side of your refrigerated enclosure; (b) thread sensor
through hole and secure probe near center-back of the enclosure; (c) apply
silicone caulk to seal hole

“CONTROL CUBE T” TEMPERATURE CONTROLLER MANUAL
Key Functions:
1. To change Setpoint: Press SET key once to display temperature setpoint,
then use the ▲ or ▼ keys to increase or decrease value. Once desired
setpoint is reached press SET key again.
2. Turning controller ON and OFF: Pressing the RST (Reset) key and holding
for 3 seconds will turn the controller OFF. Pressing the RST key again will
turn the controller back ON. The RST key can also be used to silence and
reset the AH or AL audible alarm.
Note: The WH7016C+ has two setting menus. The first menu is accessed by
pressing and holding SET key for 3 seconds. The second menu is accessed by
pressing and holding the SET and ▲ keys simultaneously for 3 seconds.
System Settings – Menu 1
1. To change system settings: Press and hold SET key for three seconds to
display system settings, then use the ▲ or ▼ keys to scroll through settings.
To change a displayed setting, press SET key once and use the ▲ or ▼
keys adjust to desired value. To exit and save settings press RST key.
Note: Controller will exit and save settings automatically after 5 seconds.
2. Symbol Details:
H or C: Mode (H= Heating C= cooling)
D: Hysteresis (or temperature offset)
LS: The minimum set limit
HS The maximum set limit
CA Temperature calibration
PT Delay time Minutes
AH High temperature alarm
AL Low temperature alarm
2.1. (H) or (C) Control Mode:
Function: The Control Mode sets the controller to either cooling (i.e.
power activated when temperature is above setpoint) or heating (power is
activated when below setpoint).
4|P a g e
“CONTROL CUBE T” TEMPERATURE CONTROLLER MANUAL
To change the Control Mode: Press and hold the SET key for 3
seconds. HC will be displayed. Press SET key one time to display the
mode and use the ▲ or ▼ keys adjust to desired value. When ready exit
the settings menu by pressing RST or waiting 5 sec.
Operation:
(C) Cooling Mode: When the measured temperature is higher than or
equal to the set value + (D) hysteresis, power will be supplied to the
appliance. When the measured temperature is below the set value, power
will be turned off.
Example: Mode is (C) Cooling, Setpoint is 50 deg. and (D)
hysteresis is set to 4 deg. When temperature increases to 54 deg.
power will be turned ON; below 50 it will turn OFF.
(H) Heating mode: When the measured temperature is higher than or
equal to the set value, power will be OFF. When the measured
temperature drops below the set value – (D) hysteresis, power will be
supplied to the appliance
Example: Mode is (H) Heating, Setpoint is 80 deg. and (D)
hysteresis is set to 2 deg. When temperature increases to 80 deg.
power will be turned ON; below 78 it will turn OFF.
2.2 (D) Hysteresis function:
Function: Hysteresis is a “offset” or temperature differential that is either
added to or subtracted from the setpoint depending on the control mode.
Default setting is 1.0 deg.
To change hysteresis: Press and hold the SET key for 3 seconds, then
the▲ once to display the hysteresis (D). Press SET key to display
hysteresis and use the ▲ or ▼ keys adjust to desired value. When ready
exit the settings menu by pressing RST or waiting 5 sec.
Operation: (See Control Mode above)

“CONTROL CUBE T” TEMPERATURE CONTROLLER MANUAL
2.3 (HS) and (LS) Upper and Lower Limit Settings
Function: Establishes the “range” of temperature measurement and
control.
Default setting: Full range of controller (-50℃ - 110℃/ -58℉ - 230℉ )
To change the Limit Settings: Press and hold the SET key for 3
seconds, then the▲ five times to display the Upper Limit (HS). Pressing▲
again will display the Lower Limit (LS). When ready exit the settings menu
by pressing RST or waiting 5 sec. Note: The setpoint needs to be set
within the new range before the limit settings are changed.
Operation: Use the (HS) and (LS) settings to reduce the range of
temperature control.
Example: (HS) is set to 90 deg. and (LS) is set to 70 deg. The
controller will display and/or control when the temperature is within
this range.
2.4 (CA) Calibration
Function: Adds (or subtracts) an “offset” in the measured vs. displayed
temperature.
Note: This is not calibration in the true sense, but simply an artificial
adjustment to the displayed temperature above or below the measured
temperature. For most applications this setting should be zero.
Default setting: 0 deg.
To change the Calibration offset: Press and hold the SET key for 3
seconds, then the▲ three times to display the calibration setting (CA).
When ready exit the settings menu by pressing RST or waiting 5 sec.
Operation: If the CA value is positive it will be added to the
measured probe temperature. If the CA value is negative it will be
subtracted.
Example: Calibration offset (CA) is set to – (minus) 2 deg. and the
probe temperature is 50 deg. Displayed value will be 48 deg.

“CONTROL CUBE T” TEMPERATURE CONTROLLER MANUAL
2.5 (PT) Delay Protection
Function: Adds an “on” delay (in minutes) before power is applied to the
appliance.
Default setting: 0 min.
To change the Delay Protection: Press and hold the SET key for 3
seconds, then the▲ four times to display the delay protection setting (PT).
When ready exit the settings menu by pressing RST or waiting 5 sec.
2.6 (AH) and (AL) Alarm High and Alarm Low Settings
Function: Enables audible alarm if temperature is below setpoint (-) AL.
and/or above setpoint (+) AH.
Default setting: 0.0 (alarms disabled)
To change the AH or AL setting: Press and hold the SET key for 3
seconds, then the▲ six times to display AH. Pressing the ▲key a
seventh time will display AL.. If the setting is 0.0 then the alarm is disabled;
any other value enables the alarm. When ready exit the settings menu by
pressing RST or waiting 5 sec.
To silence and reset the alarm: Press RST.
System Settings – Menu 2
1. To change system settings: Press and hold SET and ▲ keys simultaneously key
for three seconds to display system settings, then use the ▲ or ▼ keys to scroll
through settings. To change a displayed setting, press SET key once and use the
▲ or ▼ keys adjust to desired value. To exit and save settings press RST key.
2. Symbol Details:
C or F: (C= Celsius F= Fahrenheit)
H or L: (Needs to be set to L for this type of sensor)
ST: Increment setting; 1.0 or 0.1
AD: Alarm delay (OFF or ON)

3. Changing Settings:
Use same procedure as described earlier. Note that changing Menu 2 settings will
reset Menu 1 settings to their default. Also, you must press RST key to exit Menu 2
settings .
4. Fault messages
EEE - Temperature probe failure or not connected to controller
LLL - Temperature below control range lower limit
HHH – Temperature above control range higher limit
5. Typical settings for cooling / heating applications
Cooling (cheese, wine, beer): control mode (C); D = 3 deg; LS and HS
(default); CA = 0; PT = 1 min. AH and AL = 6 deg.
Heating (milk / curds for cheese): control mode (H); D = .2 deg; LS and
HS (default); CA = 0; PT = 0; AH and AL = 5 deg.
Sous Vide (crock pot): control mode (H); D = .1 deg; LS and HS
(default); CA = 0; PT = 1 min. AH and AL = 6 deg.
