Diagnostics Menu / 4.1 - Outdoor Unit
This section of the menu displays the diagnostic data available from the outdoor air conditioning unit.
: the state of the outdoor unit. Off – air conditioner off; Heat-on – compressor on in heating mode; Heat-off – compressor off in heating mode; Cool – cooling mode; Fan – fan mode. MiniHPC does not actually have a fan mode, but this mode is artificially sent to the outdoor unit so that it does not enter sleep mode, for example, if MiniHPC is in the state of a turned-off thermostat. : Current compressor frequency. : Speed of the outdoor unit's fan [revolutions per minute]. : Compressor power consumption. This value is calculated by the outdoor unit and may not be completely accurate. It does not account, for example, for the power consumption of the unit's heating, circulation pump, etc. This value can be calibrated in the menu 7.4 input power : Current position of the electronic expansion valve. : Voltage on the compressor [value in V]. : Current drawn by the compressor [value in A]. : Outdoor temperature measured by the sensor on the outdoor unit. If a value is also given in parentheses, that value is measured by an external sensor and sent to MiniHPC via MQTT or REST API : Temperature of the sensor located on the heat exchanger (evaporator) of the outdoor unit. : Temperature of the sensor located on the compressor discharge pipe. : Temperature of the IPM module (not every air conditioner measures this temperature; some display a constant temperature of 60°C). : During the regulation of the heating water temperature, MiniHPC simulates an attached indoor unit and sends the outdoor unit false data about the room air temperature so that it can regulate the water temperature according to the set parameters. The values of these temperatures are shown as follows: [room temperature (Tamb) / set air temperature (Tpreset)]. These temperatures can be configured in the menus 7.5 IDU heat temperature, 7.6 IDU cool temperature, and 7.7 IDU DHW temperature : Current status of defrosting of the outdoor unit. : Number of received packets with an incorrect checksum. A nonzero value indicates electrical interference on the communication cable between the outdoor and indoor units.
