Page 8: Terminology
Introductory information Terminology To provide you with a better understand- ing of the functions of your heat pump control unit, the appendix contains the chapter "Terminology" (see page 51). Energy saving tips ■ Only activate the DHW circulation pump for when DHW is drawn off reg- ularly. - Page 9 Introductory information Energy saving tips (cont.) Further recommendations: ■ Correct ventilation/airing. Briefly open windows B fully and at the same time close thermostatic radi- ator valves C (if no domestic ventila- tion system is installed). ■ Close roller shutters (if installed) at dusk.
