HP Tips & tricks during installation and troubleshooting
Introduction
The HP (Heat Pump) module is made to work in combination OpenMotics. This module will allow to built a full electric solution for Heating and Cooling in combination with a Heatpump. The HP module has following connections:
- 6x NTC (temperature) probe connections
- 4x 230VAC outputs
- 2x Relay outputs (dry contacts)
- 2x 0-10VDC inputs
- 2x 0-10VDC outputs
- 1x Aquastat input

Configuration HVAC module
Command line Interface (CLI)
The Brain(+) has a command line interface that interacts directly with the Master processor of the Brain(+). Since the HVAC module communicates directly with the Master processor, it's a good practice to test functionality on this layer before integrating on a higher layer (graphical interface, cloud and others).
The Master processor has a CLI (Command Line Interface) with about 160 different instructions. Details regarding the CLI instruction set can be found here: CLI Reference Guide AIO and AIO Tips & tricks during installation and troubleshooting
In the portal, maintenance mode can be opened (or an UART cable can be used to directly connect to the Brain(+)).
Debug information will also appear on the HVAC module. This information can be seen by connecting an UART cable on the HVAC module (115200 baud).
Connecting the HVAC module
Discovery of the HVAC module
Discovery of a new HVAC modules happens fully automatic and no manual actions are needed. In the below example, we plugged a new Input, CAN Control and HVAC module. As you can see below on the CLI output, the 3 modules have been added just after startup of the Brain:
----------Hardware Check------------ FRAM found EEPROM found (255) **I2C2 failed, address=152 i2cMode=4** **DAC5574 not found** Brain detected AT24C02 found MCP7940 RTC found -> Clock is running PCA9534_1 found PCA9539_1 found PCA9539_2 found LM75 found Std (125kbps) CAN settings used CAN speed is set at 125kbps Search started New Input module (I) found: 073.017.243.000 New Can Control module found: 067.051.255.000 New Output module (O) found: 079.023.125.000 Search done
