During standard operation of the controller, 

graphic

 display shows the main page. Apart from the selected scheme, the 

display also shows: 

- operation mode  (or type of alarm), 

- current time, 

- collector temperature, 

- current temperature of the heat tank, 

- temperature of all additional sensors depending on selected configuration. 

 

On the right-hand side of the screen you may see the following icons: 

Active operation mode icon

 

Icon of active additional device (peripherals)

 

 

Automatic operation mode

 

 

Circulating pump

 

 

Collector defrosting mode

 

 

Pellet CH boiler fire-up (voltage-free 
signal)

 

 

Holiday mode

 

 

Heater

 

 

Collector overheating  (alarm mode)

 

 

 

Anti - legionella

 

 

Sensor damage (alarm mode)

 

1/17

 

Selected scheme

 

 

If one of the sensors is damaged, an additional icon will be flashing

 in the place of the damaged sensor temperature. 

The icon indicates which sensor was disconnected or damaged.  

Additionally, the pump icon will be displayed on the system scheme (if the pump is working/rotating) or/and the valve 
icon will appear (with an indication of current circulation direction).
