1 Introduction

Thank you or choosing a Dimplex Heat Pump.

Dimplex A-Class is designed speci ically to

maximise year-round heating system e iciency,

no matter the weather conditions. Its high

e iciency means lower running costs and a

aster payback or the homeowner.

How the heat pump works

The operation o the heat pump is shown in

igure 1 below. A heat pump works on the same

principle as a ridge using a re rigerant luid

which boils at a low temperature. Free energy is

take rom the air to boil the re rigerant in the

evaporator coil (1), changing it rom a liquid to

a vapour. This low grade heat is upgraded by

the compressor (2) increasing its pressure, and

consequently its temperature, to a use ul high

temperature. The heat is trans erred to your

heating system by the condenser (3), where the

re rigerant becomes liquid once again. The

liquid re rigerant is then expanded using an

expansion valve to a low pressure luid be ore

repeating the cycle. 60-80% o the heat

generated by the heat pump comes rom the

ree energy taken rom the air, compared to 20-

40% generated by the electricity used to power

the heat pump.

.1 Tips and advice to follow when

using your new heat pump

• Glen Dimplex heat pumps are designed

with e iciency in mind. As a result o

using our renewable technology rather

than combustion or ossil uels, the hot

water used to heat your home is heated

gradually, which allows the system to only

use as much energy as is required.

Because o this however, it will be

necessary to set your new heating system

to heat water/rooms a little while be ore

you would have had to set a traditional oil

or gas heating system, in order to allow

ample time or the desired temperatures

to be achieved.

• When using a Glen Dimplex heating

system, it is important to remember that

it is not possible to have the DHW and

space heating switched on at the same

time. I , or example, you require both hot

water and heating in the morning, it is

recommended to use the DHW unction

irst, ollowed by the space heating. The

insulation used on our cylinders ensures

that hot water will stay hot or as long as

possible, however it generally takes longer

to initially heat the DHW than or the

space heating to take e ect.

When programming timer settings on the

UI, please check that the timer set or the

space heating and DHW do not overlap, as

the DHW unction will automatically take

priority.

3 Heating System Controller

(User Interface)

The controller/user inter ace that is supplied

with the Dimplex A-Class heat pump is used as

a heat pump controller as well as a heating and

domestic hot water (DHW) controller. It is also

the pre erred option or use as a temperature

control device. The unctions available or each

o these applications are explained in section 4.

When your heat pump system was installed, the

installer would have discussed with you the

di erent temperature control device options

available. While only one user inter ace is

currently available per system, there are

additional options o either temperature probes

or mechanical thermostats, which can be used

to control the temperature in up to our zones.

Mechanical thermostats provide less control

over the heating system, while the temperature

probe option allows the heat pump to sense

changes in demand and adjust accordingly. The

temperature probe option is generally

recommended over the mechanical thermostat

option.

A zone is de ined as the physical area o your

home in which temperatures are controlled by

each individual device. For example, you might

have the user inter ace installed in your living

area, in which case this may be re erred to as

zone 1. You may also install a temperature

probe upstairs in the sleeping/bedroom area,

which would then be designated as zone 2, and

so on. Extra zones are an additional, optional

eature o the heating system. The standard

package comes with one User Inter ace and the

possibility o our separate zones.

Zone temperatures:

This icon shows the zone 1 temperature. The

temperature o all zones can be controlled using

this menu, as shown in igure 7(a) and 7(b).

Operating mode:

This icon shows what mode the space heating is

running in: ON, OFF or TIMER. At initial start-up

the space heating setting is OFF and will need

to be adjusted to constantly ON or in TIMER

mode. Selecting the TIMER menu allows you to

select a prede ined programme which can be

4.3.1 Comfort levels

I you eel that the desired room air

temperature in your home is not being reached,

it is possible to increase the com ort level

settings on your UI, which changes the water

input temperature or your heating system.

Glen Dimplex heat pumps allow or weather

compensation, and operate on a heating curve,

which will set the low (water input)

temperature automatically depending on

outside conditions. The heating curves or each

zone in your home would have been set up by

the installer during the heat pump installation.

Changing the water input temperature will

change the response time or your heating

system.

In the com ort level submenu, as shown in

igure 8, it is possible to alter the water input

temperature or your system within a range o

6°C (-3°C to +3°C).

A warmer water input temperature will

increase energy consumption and

therefore running costs - every 1°C

reduction in the system’s water input

temperature will reduce energy

consumption by .5%.

You can set your com ort level to automatically

remain set or anything rom 1 hour to 14 days

( or short term changes or seasonal

adjustments), or i you wish to keep your

settings permanently, there is a permanent

setting option which will stay as set until you

change it again manually. The de ault com ort

level setting is 0.

4.3. Operating modes

Clicking on the clock icon allows you to select

rom one o three running modes:

TIMER mode activates the pre-set timer

programmes.

ON mode turns the heating constantly on.

OFF mode turns the heating constantly o .

When the heating is set to OFF, you will be

asked or a setback temperature, as shown in

igure 9(b). This temperature is the OFF

temperature, which operates as a rost

protection eature. It is also the minimum room

temperature when the system is idle, and is

used as the set point temperature in between

programmed TIMER periods. It is set to a

de ault o 15°C but can be changed to suit the

climate.

4.3.3 Setting time periods

Time periods are pre-set but can be changed. 5

di erent ‘Options’ are available, each o which

can have up to 3 time period settings, and are

accessible by selecting the ‘Setting’ icon in the

space heating menu.

re-set time periods

A number o time period have been pre-set to

typical heating time periods, to aid in quick and

easy initial set up. For example, Option 1 has

been set up as ollows:

Period 1 21°C 06:00 – 09:00

Period 2 19°C 12:00 – 14:00

Period 3 21°C 17:00 – 22:00

The pre-set time periods can be easy changed to

suit your pre erence by selecting the Space

heating menu and the ‘Setting’ option.

Quiet Mode

Runs the heat pump in quiet mode, which may

be desirable at night i the heat pump is located

near bedrooms. Please note that in quiet mode it

will take longer to reach the set temperature as

the heat pump is running at a lower capacity in

order to reduce noise.

4.4 Domestic hot water (DHW)

Selecting the domestic hot water icon rom the

home screen will take you to the domestic hot

water menu, shown in igure 11.

Water temperature:

This icon shows the set point temperature o the

DHW. You can also adjust the set point hot water

temperature here by turning the dial up or down

and then pressing it in to con irm, provided that

the TIMER mode is not set (TIMER mode

overrides all temperature changes except the

temporary modes explained in section 4.6 and

the Boost unction).

A practical temperature or domestic hot water is

45°C. The A-Class cylinder and heat pump

together can typically achieve up to 60°C. The

maximum achievable temperature or the heat

pump is measured during commissioning, and an

indication is given when selecting the DHW set-

point i the immersion will be required to achieve

the set-point (adjusting the temperature o the

DHW above the maximum cylinder temperature

causes the immersion to be used to heat the

water above this maximum temperature).

Operating mode:

This icon shows what mode the domestic hot

water is running in: ON, OFF or TIMER. The

de ault setting is OFF, but can be adjusted to

constantly on or in TIMER mode by selecting the

mode icon and turning the dial. Selecting the

TIMER menu allows you to select a prede ined

programme which can be modi ied in the ‘Setting’

menu.

example, i you arrive home rom work early

and want to take a shower, but the DHW isn’t

scheduled to run until later. In this case, the

Boost unction can be used to override the

TIMER until the water in the cylinder reaches

the set point temperature.

Disinfect:

Enable disin ection and set the time when it will

occur.

Setting:

Set up time periods or the hot water to come

on and o . Time periods (in the ‘Setting’ menu)

are pre-set but can be modi ied. There are

three types o settings you can store at one

time; Weekdays, Weekends and Custom time

periods, shown in igure 13(a). Up to 3 periods

can be chosen or each setting, as shown in

igure 13(b).

The time periods selected in ‘Setting’ can be

applied in TIMER mode, as shown in igure 14.

4.4.1 Disinfection

Disin ection is a unction which keeps the level

o legionella bacteria in the cylinder under

acceptable levels. This is carried out by heating

the hot water in the cylinder to a high

temperature or a minimum set time. The

disin ection settings are pre-de ined in the User

inter ace. I you wish you can change the

requency o disin ection and the time that it

takes place, as shown in igure 10.

4.5 Information

Selecting the in ormation icon rom the home

screen will take you to the in ormation menu.

The in ormation menu provides you with details

o the settings which are currently active, as

shown in igure 16.

The icons will be highlighted in green i that

part o the system is on and white i it is o .

Some o the symbols displayed on this screen

will depend on the set up o your heating

system, there ore some icons may not be

visible. In this screen, you can also access an

additional menu which allows you to change the

date and time, the outside o temperature and

to view a list o any messages that occur. This

menu is accessed by turning the rotary dial to

the ‘Login’ button and middle clicking. Turn the

dial to ‘998’ and middle click again.

4.5.1 Adjusting the date and time

The date and time will be set during installation.

I or any reason you need to adjust these

settings you can do so by using the ‘Login’

button in the in ormation screen, as shown in

igure 17. Turn the rotary dial to the login

button and middle click. Turn the dial to ‘998’

and middle click again.

4.5. Information – Message list

I the in ormation symbol on the home screen is

highlighted orange, it means a minor ault has

occurred. When the message icon is highlighted

in red on the home screen, it usually means

there is an issue with the operation o the heat

pump. When you see this you must contact the

heat pump installer and provide them with the

error code.

The ull message list can be viewed by entering

998, similar to the date and time menu

described in section 4.5.1. I a message is

active, it will be highlighted orange. Selecting

the message (by middle clicking the rotary dial)

will open a list o details about the system

operation the moment the message occurred.

4.5.3 Changing outside off temperature

You may not require your heat pump to come

on in warmer months, when the outside air

temperature reaches a certain level. You can

change the outside o temperature in the

in ormation menu, by entering ‘Login = 998’ as

be ore. In this menu you will see a submenu

called ‘General DHW & Heating Control’.

Accessing this menu will allow you to change

the outside o temperature, by clicking on the

temperature and turning the dial to increase or

decrease the temperature.

I the outside o temperature is set too low or

your environment (e.g. de ault outside o

temperature is 18°C) and the temperature

outside surpasses this (e.g. it is 20°C outside

during summer), the heating will be switched

o and will revert back to the set back

temperature (see section 4.3.3) until the next

change. This can be prevented by increasing

the outside o temperature.

You will also ind a number o other sub menus

in the ‘Login = 998’ menu. These menus display

in ormation about temperatures in each zone,

which may be required when speaking to a

service agent.
