4.1 The ÄssäControl system

ÄssäControl display ver. 1

ÄssäControl is a logic-based control system that takes both the outdoor temperature as

well as ambient indoor conditions into consideration. The system’s controller regulates

the heating system’s flow temperature based on the outdoor temperature using a

heating curve consisting of seven points. This keeps the indoor temperature at an

even, comfortable level regardless of changes in outdoor temperature.

Typically, ÄssäControl is used to regulate both domestic hot water heating and one

or two heating circuits. If the heat pump is not used for domestic hot water heating,

the number of heating circuits can be increased to 3. The system is also capable of

controlling external heat sources.

4.2 Operating the touchscreen

Main view page 1 ver. 1

Main view page 2 ver. 1

When the heat pump is switched on, the main view will be displayed. Consisting of two

pages, the main view provides access to eight 

quick functions

. The current outdoor

and indoor temperature will also be displayed.
