PERATING THE UNIT
5.1. Introduction
The heat pump system is designed to provide you domestic hot water
for many years at low energy consumption.
To get the most comfort with the lowest running cost of your system, it
is very important to observe the items listed below.
Defining possible schedule timer actions for each day and filling out
the form at the very end of this manual can help you minimize the
energy consumption. Ask your installer for support if required.
■
Make sure the heat pump system works at the lowest possible
hot water temperature required to fulfill your domestic hot water
needs.
To optimize this, make sure the auto adaptive set point is used.
Refer to "Auto adaptive set point operation" on page 9.
■
Recommendation
■ If you set the set point manually, make sure the domestic hot
water is only heated up to the domestic hot water
temperature you require.
Start with a low domestic hot water temperature set point
(e.g. 45°C), and only increase if you feel that the domestic
hot water supply temperature is not sufficient.
INFORMATION
Use the auto adaptive set point to optimise.
■ Also keep hours with low electricity cost tariffs in mind.
To do this, program the domestic water heating schedule
timer. Refer to "Programming" in chapter "Programming and
consulting the schedule timer" on page 9.
INFORMATION
There is a default schedule timer set (refer to
"Schedule timer operation" on page 7).
