2. GENERAL SAFETY PRECAUTIONS

The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.

Do not touch any switch with wet fingers. Touching a switch
with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.

To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PA RT S

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.

WARNING

■ Never directly touch any accidental leaking
refrigerant. This could result in severe wounds caused
by frostbite.

■ Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts.

Your hands may suffer burns or frostbite if you touch
the refrigerant pipes. To avoid injury, give the pipes
time to return to normal temperature or, if you must
touch them, be sure to wear proper gloves.

CAUTION

Do not rinse the unit. This may cause electric shocks or
fire.

3. INTRODUCTION

4. QUICK START-UP OF THE UNIT

3.1. This manual

This manual describes how to start up and switch off the unit, set
parameters and configure the schedule timer by means of the
controller, maintain the unit and solve operational problems.

INFORMATION

Refer to the installation manual of the unit for installation
procedures.

3.2. General information

Thank you for purchasing the domestic hot water heat pump.

This unit consists out of two parts, a heat pump unit
(EKHVWQ002AAV3) and a domestic hot water tank (EKHHS). Only
this type of domestic hot water tanks can be combined with the heat
pump unit.

The domestic hot water tank is available in two sizes: 200 and 260
litre and can be mounted on top of the heat pump unit. For installation
of the domestic hot water tank on the floor next to the heat pump unit,
the dedicated EKFMHHSAA connection kit is required.

The domestic hot water tank contains an electric heater of 1.5 kW as
backup system.

In this chapter the step-by-step procedure is explained for starting up
domestic water heating.

The more detailed information of how the unit must be operated is
explained in the chapter "Operating the unit" on page 4.

The quick start-up offers the user the possibility to start up the
system before reading the entire manual.

5. OPERATING 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).

5.2. Operating the digital controller

Operating the domestic hot water heat pump comes down to
operating the digital controller.

CAUTION

■ 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.

■ Do not rinse the indoor unit. This may cause electric
shock or fire.

■ Do not climb, sit or stand on top of the unit.

■ Do not place any objects or equipment on the unit top

plate.

Features and functions

The digital controller is a state of the art controller that offers full
control over your installation.

NOTICE

■ Descriptions in this manual that apply to a specific
installation or that depend on the installed equipment,
are marked with an asterisk (*).

■ Some functions described in this manual may not be
available or should not be available. Ask your installer
or your local dealer for more information on
permission levels.

Basic controller functions

The basic controller functions are:

■ Turning the unit ON/OFF.

■ Schedule timer/continuous mode

■ Selection of features:

- quiet mode (refer to page 8),

- auto adaptive set point control (refer to page 9).

■ Temperature set point adjustment (refer to page 6).

■ Powerful mode

The digital controller supports a power cut off of maximum 2 hours.
When autorestart is enabled (see "Field settings" in the installation

manual) this allows a power supply shut down of 2 hours without user

intervention (e.g. benefit kWh rate power supply).
