A complete step-by-step instruction to both sw and hw installation can be found here. Below is a couple of tips how to connect ThermIQ-MQTT and ThermIQ-Room to the heatpump.
- First step to install ThermIQ-MQTT and ThermIQ-Room in your heatpump is to turn off the main switch and open the front to locate the main control-board.
- The main control-board is often located on the front behind a black plastic cover. On the top left side of the board you will find a connector labeled EXT to which you should connect the ThermIQ-MQTT/Room.
- Attach an USB cable and an USB Power adaptor able to deliver 1A to ThermIQ-MQTT/Room. Put on front cover and turn on the main switch.
One neat way to power the ThermIQ-MQTT/Room is to put a power outlet or a switched power supply on the DIN rail in the heatpump.
