Accessing Software Updates

Periodically the software is updated with enhancements, menu changes or must be reloaded such as when a control board is replaced or updated with a newer model control. Use the following procedures to reload the software.

Water Detection Software

The purpose of the water detection software is to prevent a frypot filled with water from boiling or pressurizing. The software works by preventing the fryer from leaving the melt cycle and entering a cook cycle, until the oil reaches 215°F. When the frypot is turned on, the software measures the temperature of the liquid in the frypot. If the temperature of the liquid in the frypot is below 215°F, the fryer enters the melt cycle. During the melt cycle, the solenoid remains open and does not allow the frypot to pressurize.

The melt cycle heats the liquid using a pulse rate that prevents water from boiling. If the liquid temperature in the frypot is below 200°F, then the fryer heats with an 18/40 pulse rate (18 seconds on, 22 seconds off) for electric units and 25/40 (25 seconds on, 15 seconds off) for gas units. Once the liquid temperature reaches 200°F, the pulse rate is reduced to 5/40 (5 seconds on, 35 seconds off) for electric units and to 8/ 40 (8 seconds on, 32 seconds off) for gas units. These reduced pulse rates provide insufficient energy to allow water to reach a boiling point of 212°F in the frypot, but will allow oil to reach 215°F. Once the liquid reaches 215°F the software allows the fryer to enter the cook cycle, and the vat to pressurize.

Control Board Updates

The control board is operated by an onboard Micro SD card, which is loaded with HP software during the factory programming process and/or installation; it occasionally requires an update. The software on a control board must be loaded from a USB drive. The file type used for loading software is an .hpf (Henny Penny Flash) file. All . hpf files are encrypted and are checksum protected, in order to prevent accidental or malicious changes to the official HP software. In addition, the boot-loader program on the control board allows selection of only the .hpf files that are designed for that specific unit’s control assembly. This prevents accidental loading of say a holding cabinet in to a pressure fryer control, or similar mistake.

USB Port Overview

The external USB port on the front of the unit is connected to an internal USB port on the control board with a short wiring harness. If the external USB port fails, access and use the internal USB port by lowering the control board from the unit to gain access to the internal USB port. Refer to USB Port Replacement.

SanDisk USB Flash Drive

It is recommended that before performing a service call, technicians check for and download the latest version of the software, and then update the unit while on site. Updated versions contain the latest customer requested features and fixes.

Two SanDisk brand USB flash drives with plastic tips, 2 to 8 GB of storage space and formatted with FAT 32 are shipping with each unit. One is zip tied externally to the front of the unit and the second internally to the back of the control board. Each contains the most current version .hpf file for the unit based on ship date. If the customer’s USB drives are missing or outdated, refer to Version Updates.

Version Updates

Current versions of the software are maintained on the HP Extranet by unit model and software version. Because the customer’s on site USB flash drive may be outdated. Download the newest version of the software to an approved plastic tipped USB flash drive before performing a service call. Refer to SanDisk USB Flash Drive and Access the Extranet to download the most current version of software.

Accessing the Extranet

The better the quality of ISP service the quicker the access to the Extranet. Always use a non-public, secure connection to the Extranet to prevent non-authorized access. Access the HP Extranet by doing the following:

1. From a Internet connected laptop, navigate to MyHennyPenny.

2. Scroll down to the Quick Links on the right side of the page. The Extranet- Distributor Network link displays.

3. Click the Extranet-Distributor Network link. Wait, a login displays.

4. Type your HP assigned e-mail address in the Email address text box and then your user defined password in the Password text box. 5) Click the LOGIN button. The HP Extranet home page displays.

Locating and Downloading the Latest Version of Software

1. In the upper right corner of the HP Extranet home page, type Software Update in the search box, and then press Enter. All Documents displays in the left navigation bar.

2. Click the Software Update link from the All Document menu list. A list of updates displays in the center navigation bar.

3. Scroll through the list and locate the latest .hpf file and then click on the associated READ MORE> link. A pop-up window displays asking if you want to save the file. If not, ensure pop-up blockers are disabled.

   Optionally download the file by right-clicking the READ MORE> link and selecting the Save Target As option.

4. Click Save and save the file to the laptop using the default file name.

   Do not change the file name, it is used during the reflashing process and to differentiate customer specific information.

5. Move the file to an approved plastic tipped USB flash drive. Refer to SanDisk USB Flash Drive.
