2. FOX-2005 Installation Instructions
- Panel Cutout Preparation: Cut a rectangular hole on the electrical cabinet panel with precise dimensions: 71mm (Width) x 29mm (Height). Ensure the surface is flat and free from burrs to allow for easy installation.
- Installing the Device into the Panel: Insert the FOX-2005 controller into the cutout from the front of the panel, aligning it properly into position.
- Securing the Device: Use the mounting clips provided with the product. Attach the clips into the side grooves of the device from inside the panel to securely hold the controller in place, ensuring it does not shift during operation.

a) Notes on electrical safety
- Completely disconnect the power before connecting: Before performing any wiring, make sure all power sources are disconnected to avoid the risk of electric shock or damage to the equipment.
- Use terminals for electrical wires: The ends of the wires should be neatly crimped to ensure good contact and increase safety when connecting.
- Protect the contacts with a contactor or auxiliary circuit breaker: Do not supply load directly through the contacts of the controller. Use a contactor or intermediate circuit breaker to protect the contacts from overload, helping the equipment operate more stably and durably.
b) Instructions for connecting temperature sensors
The FOX-2005 controller comes with 2 NTC sensors:- First sensor (black): used to measure room temperature
- Second sensor (yellow): used to measure evaporator temperature
How to wire the sensor:| Wire type | Connection location |
| White wire (of both sensors) | Pin number 9 |
| Black wire of black sensor | Pin number 8 |
| Black wire of yellow sensor | Pin number 10 |
⚠️ Note: It is necessary to carefully check the wire color before connecting to avoid confusion, affecting the device's ability to read the accurate temperature.c) Electrical connections and equipment
| | Number foot |
| Compressor | 3 + 12 |
| Fan | 2 + 12 |
| Defrost | 1 + 12 |
| Warning | 5 + 12 |
| Short-circuit the pins with short pieces of wire. | 11 + 6 + 4 |
4. Function keys and on-screen indicators
Front of Conotec FOX-2005
- SET: Setting key – used to enter the operating parameter setting mode.
- Defrost: Key used to activate or stop manual defrosting as needed.
- Arrow ▲: Used to move through the parameters, and increase the value when setting.
- Arrow ▼: Used to move through the parameters, and decrease the value when setting.| Symbol | Function |
S1 | Room temperature sensor indicator (probe S1) is active. |
S2 | The evaporator temperature sensor indicator (probe S2) is working. |
K1 | Compressor output indicator light. Light is on → compressor is running. |
K2 | Fan output indicator light. Light is on → fan is running. |
K3 | Defrost output indicator light. Light is on → the system is in defrost mode. |
K4S | Warning output indicator light. Light is on → warehouse temperature exceeds the allowable threshold. |
5. Set the SET (OFF) point on FOX-2005
The SET point (or OFF point) is the temperature threshold at which the control output will be turned off (OFF). When the room temperature (measured value from sensor S1) drops to or below the SET point, the controller will stop the compressor to maintain a stable temperature.
Steps to set SET point:
Press the SET key
→ The display shows "SEt".
Press the SET key again
→ The display shows the SET point value being set (this value will flash).
Use the ▲ or ▼ arrow keys
→ Change the value as desired.
Press the SET key again to confirm and save the value.
→ The display returns to show the current temperature.
6. Program installation
Unlock keyboard before installation
The FOX-2005 controller is designed with an automatic keypad lock feature to prevent accidental parameter changes during operation.
When the keypad is in a locked state, the user can only view the parameters – no editing or setting is possible.
Before proceeding with the program installation, the keyboard must be unlocked to be able to adjust the parameters as required.Note: Unlocking ensures that the user has full access to the device, especially during first-time setup or when changing the cold storage operating configuration.
a) Access the installation program
Press and hold the SET key for more than 5 seconds → The display will display the first parameter, usually LoC (keyboard lock) 
. b) Unlock the keyboard (if locked)
Note: The FOX-2005 keyboard automatically locks every time it exits setup mode, to avoid accidental operation.
At the LoC parameter display screen ,Press the SET key to enter change.
Use the up arrow (▲) or down arrow (▼) key to move the value from LoC (Lock) → LoF (Unlock)
.
Press the SET key again to save the value.
→ The screen will return to the next parameter display state, and you can continue setting. c) How to set parameters
Once the keyboard is unlocked, you can proceed to set the parameters needed to operate the cold storage as required. Below are the basic operations to access, adjust and save the parameters:
- At the display of a parameter, press the SET setting key to display the value of the parameter
- At the display of a parameter, press the ▲ or ▼ arrow keys to move to another parameter
- At the display of the parameter value, press the ▲ or ▼ arrow keys to change the value
- At the display of the parameter value, press the SET setting key to return to the parameter display screen
d) Explain the meaning of the parameters
7. Activate freezer defrost
In addition to the automatic defrost function based on programmed parameters, the FOX-2005 controller also supports manual defrost activation or stop at any time, which is very useful in cases where the evaporator needs to be cleaned or quick troubleshooting is required.
Activate manual defrost mode
Press and hold the "Defrost" key
in more than 4 seconds
→ The defrost indicator light (K3) on the display will light up, indicating that the defrost process is active.
Stop manual defrost mode
Press and hold the "Defrost" key for more than 4 seconds
→ The defrost indicator light (K3) will turn off, indicating that the defrost process has ended.8. FOX-2005 Installation Reference
