4. DHW temperature control

The  DHW  temperature  is  controlled  by  a 

proportional valve – the PM controller. The DHW 

temperature control is realized by turning the 

lever towards the red (hot) or blue (cold) mark. The 

temperature should be set to 45-48 °C at normal 

use (7-8 l/min). 

The temperature should never 

exceed 55 °C

 to avoid lime scale precipitation in 

the heat exchanger.

If it is not possible to set the temperature according 

to the above recommendations, it is recommended 

to change the standard controller setting.

PM controller

The  PM  controller  can  operate  in  three  basic  

settings:

- High

- Standard – default

- Low

Approximate setting of PM controller is dependent on 

district heating supply temperature and ∆p:

wrench,

- remove plastic cap,

- mount lever again and turn it: 

- 1 rotation 

clockwise – high

- 1 rotation 

counter – clockwise – low

,

- mount cap and lever again.
