Overview of the H60 device.
The H60 solution are sold as a main unit that has to be completed with a heat pump cable/interface specific for the intended model of heat pump.
The first thing to do is to attach the cable-interface to the main unit. For this, remove 4 screws at the bottom of the main unit box and open the cover. Attach the interface cable circuit board on the two header connectors on the main board. Make sure to align it properly to the pins the right way. Miss-aligning the interface could damage the electronics.
Now attach the cover again using the 4 screws.
The USB Port
On the side there is a micro USB port that are normally not used. The intended use is to support advanced management, development, reflash and special solutions. Don’t ever connect a power source or computer to the USB port at the same time the H60 is connected to a heat pumps power. This could cause damage to the Computer, H60 unit and the heat pump. If you for some reason need to use the USB port, disconnect the heat pump power cable (violet) from the cable interface first so the unit is powered from the USB jack instead. The setting for the port is 115200 baud.
The device has two buttons on its side.
The Reset button will restart the unit, normally never used but if it gets stuck in an update or something it may be useful.
The Init button has two functions.
By holding it for 2 seconds, the unit will be put in AP (Access Point) mode so you can access the unit by connecting to it’s SSID “Husdata H60”. See support section. By holding the button for 6 seconds until the green led goes dark the unit will load default / factory reset config.
The Red led is flashing irregular when the unit has contact with and communicating with the heat pump.
The Green led is the Wi-Fi Connection status and should flash slowly in normal operations.
See suport sections for LED details and troubleshooting.
The H60 is a dual processor solution based on PIC and ESP controllers.
The PIC microconroller firmware is based on our prooved H1 interface solutions and are handling all heat pump communications.
This is performed independantly from the Wifi ESP controller. So if the ESP restarts, loose communications, or whaterver disturbance that could occur, it will not disturb or give trouble codes on the heatpump as the PIC controller remains unaffected. The ESP8266 is a well known system on a chip platform. Hard core developers has the possibility to develop their own custom firmware from scratch. The H60 USB interface module is fully compatible with the Arduino environment as an Wemos D1 Mini unit.
