HP Module Release Notes

General

The HP Module firmware is published as Open Source since firmware release V6.0.x. Below you'll find all the changes since that release.

The firmware updates happening in the Openmotics portal (Settings - Update) contain not only the firmware update of the Master, but also the firmware of other modules as well as the updates for the Beagle Bone Black. All these different firmware updates are assembled in a package which get's a general version number. This version number which you see in the portal is not the same as the Firmware Version of the Master. To check which firmware version is installed on the Master or any other module, in the Openmotics portal, go to Settings - Maintenance and open maintenance mode by pressing the Connect button. Type the instruction firmware version to read the Master Firmware version.

Important Notes:

• V6.x.y only works with Gen 3 hardware
• For more information, see HP Tips & tricks during installation and troubleshooting

V6.0.6

Date: 10/01/2022

Added functionality

• Eeprom Memory model has been changed to allow future parameters for PID configuration
• This new memory model has been implemented in this version
• When the Thermostat setpoint is updated in the Master (by using CLI instruction "thermostat setpoint write"), these setpoints are distributed to the HVAC module by a modified RS485 instruction.
• UART Debug information has been extended with more information
• The PID filter output is linked to the DAC outputs of the HVAC module
• When a Setpoint Min (for cooling) or Max (for heating) is specified and a higher setpoint is written by the Master, the HVAC module will automatically limit this setpoint
• When a setpoint in the HVAC module changes, it will write this updated value in eeprom which guarantees that the correct setpoint is used when the module resets or communication is lost
• A failsafe setpoint temperature is added: When the module goes in failsafe or just after startup of the HVAC module, this thermostat failsafe setpoint temperature is loaded.

V6.0.5

Date: 04/01/2022

Resolved bugs

• When performing a factory reset, the ID's of the Sensor module didn't got erased. This release solves this issue.

Added functionality

• Failsafe function has been added:
  • When RS485 power is lost, the HVAC module goes in Failsafe warning state
  • When power is lost for more then 30 seconds, The HVAC module goes in failsafe state (actions can now be linked to this failsafe state)
  • When power was lost for more then 2 seconds and then restored, the HVAC module will reset
• Execution time and execution setting for each PID filter has been added
• Maximum Temperature Setpoint per PID filter has been added
• Heating/Cooling per PID filter has been added
  • Heating has his own set of PID parameters
  • Cooling has his own set of PID parameters
  • An eeprom setting will define, for each PID filter, if it's configured as heating or cooling PID filter

V6.0.4

Date: 30/12/2021

Added functionality

• Sensor measurement frequency has been added: Eeprom parameter 95 will set the sensor refresh rate. This will allow the user to set the correct sensor measurement rate.
• Sensor debug information via direct UART has been added: This can be configured via eeprom parameter 94.
• PID epic has been added:
  • Eeprom Memory model has been created, see HP Tips & tricks during installation and troubleshooting
  • Loading of all PID parameters from eeprom
  • Checking loaded PID parameters, abnormal values will be overruled by default values
  • 2 simultaneous PID filters can run, this can be extended to maximum 6
  • Each PID filter can be linked to it's own temperature sensor and output (configurable via eeprom parameters)
  • All PID parameters can be programmed via CLI instruction "eeprom write"
  • When a PID Eeprom parameter has been changed, it will be automatically loaded in RAM memory and will be active immediately
  • UART debugging has been added for testing and setting the right PID parameters
• Factory Reset RS485 instruction has been added: The Master can perform a Factory reset of the HVAC module.

V6.0.3

Date: 28/12/2021

Added functionality

• This version supports the automatic detection of the HP module on the Brain(+)
  • When a new module is linked to a Brain, the Brain will do the automatic handshaking and will add the HP module
  • An output module and a sensor module will be added without user intervention
  • When performing "error list" in the CLI will give you the following result (modules with "H" are HP modules):
