PERATING THE UNIT
I
NTRODUCTION
The
heat pump system is designed to provide
you a comfortable indoor climate for many years at low energy
consumption.
To get the most comfort with the lowest energy consumption out 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
the lowest possible hot water temperature required to heat your
house.
To optimize this, make sure the weather dependent set point is
used and configured to match the installation environment.
Refer to "Field settings" on page 10.
Make sure the equilibrium temperature field setting is configured
correctly.
Refer to "Field settings" on page 10.
This function applies to operation of the backup heater. Setting
the equilibrium temperature correctly will avoid the backup
heater to operate when the heat pump has sufficient capacity to
heat up your house.
It is advised to install a room thermostat connected to the indoor
unit. This will prevent excessive space heating and will stop the
outdoor unit and the indoor circulation pump when the room
temperature is above the thermostat set point.
Next recommendations only apply to installations with an
optional domestic hot water tank.
Make sure the domestic 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.
Make sure both the domestic water heating and booster
heating only start 1 to 2 hours before you expect domestic
hot water usage.
In case you only need a lot of domestic hot water in the
evening or in the morning, only allow domestic water heating
during early morning and early evening. Also keep hours with
low electricity cost tariffs in mind.
To do this, program both the domestic water heating and
booster heating schedule timer. Refer to Programming in
chapter "Programming and consulting the schedule timer" on
page 7.

PERATING THE DIGITAL CONTROLLER
Operating the HKHB* unit comes down to operating the digital
controller.
Never let the digital controller get wet. This may cause an
electric shock or fire.
Never press the buttons of the digital controller with a hard,
pointed object. This may damage the digital controller.
Never inspect or service the digital controller yourself, ask
a qualified service person to do this.
Features and functions
The digital controller is a state of the art controller that offers full
control over your installation. It can control a cooling/heating and a
heating only installation.
Both installations are available with a 6 kW backup heater and can be
integrated in a sytem with an optional domestic hot water tank with
booster heater.
