Use this basic guide to set hot water and heating temperatures, heating

schedules, and to remedy simple faults including resets and repressuring

the system.

CONTENTS

The heat pump system operates in a more sophisticated way to most traditional

heating systems, and as a result the way it heats will dier slightly for what we

have grown accustomed to with traditional boilers.

The new heat pump systems operates on the principles of conserving and

maintaining a comfortable heating temperature throughout the day, rather than

emitting large amounts of heat at certain points in the day, like older heating

systems.

The sophisticated system is also Weather Compensating, meaning that it measures

the outside temperature and accommodates your indoor heating accordingly.

Please remember, the more you ask the system to uctuate, the harder it has to

work, and therefore the more inecient its performance will be. We recommend

for the most ecient performance and consistent comfort experience, that you

leave the system to operate at the settings we have programmed.

A key thing to remember is that this system operates on a gradual basis, and

this is how it maintains an ecient performance. Please allow some time for the

system to respond to any changes.

Occasionally you may notice that your heating is set to be on, but you will feel

no heat coming out of the radiators. The reasons for this will often be that the

system has measured the temperature of the room/indoor environment and if

the temperature is already met there is no need for the radiators to be running.

The system does this to retain its energy and maintain eciency. In this instance,

it is best to check what the temperature of the room feels like to you. If you do feel

cold, you can always turn the temperature up on the thermostat for a temporary

boost (please refer to p3 of this guide).

Heating

Select ‘Indoor Climate’ by pressing ‘OK’ from the Main Menu.

N.B. After resetting temperature please wait 24 hours for room temperature

to stabilise before changing settings again.

To change the room temperature, use the control knob to set a new value.

Conrm the new setting by pressing the OK button.

For systems that are controlled by a room sensor, the value in the display

appears as a temperture in °C:

Setting range: 5°C - 30°C

Setting range: -10 to +10

Default value: 0

Default Value: 20°C

To change the room temperature, use the control knob to set the desired

temperature in the display. Conrm new temperature by pressing “OK”.

Setting Hot Water Capacity

To set the hot water capacity, from the main menu scroll down to the “HOT

WATER” option and press “OK”.

USER GUIDE

evoecohomes.co.uk

To temporarily increase hot water select “temporary lux”. From there you

can navigate through a selection (see next page):

Temporary lux

To permanently increase hot water volume, select ‘Comfort Mode’ from

the HOT WATER Menu. The comfort mode has 4 options depending on the

size and usage requirements of your home.

The default setting is “o’. Scroll through the options to nd the best

extra heating option for your requirements. Press “OK” to tick the circle.

When you return to the “HOT WATER” menu, your selection will appear

on the right side of the temporary lux tab.

If a time period has been selected (3/6/12hrs), a timer will appear

showing time remaining in temporary lux mode.

N.B. This setting cannot produce any extra hot water if comfort modecomfort mode is

already set to “luxury”. See below for more info on comfort modecomfort mode.

Comfort Mode

USER GUIDE

evoecohomes.co.uk

Smart ControlSmart Control: N/A

EconomyEconomy: This mode produces less hot water, but is more economical.

This mode is useful in smaller households with a small hot water

requirement. Heats your hot water to 48°C and reheats

when the temperature drops to 42°C.

NormalNormal: This gives more hot water than economy mode, and is suitable

for most households. Heats your hot water to 50°C and reheats when the

temperature drops to 46°C.

LuxuryLuxury: This produces the greatest possible amount of hot water. The

compressor and immersion heater are used in this mode, which may

incur higher operating costs. Heats your hot water to 50°C and reheats

when the temperature drops to 49°C.

Highlight the comfort level you require, select OK. This is now selected.

Press ‘Back’ twice to return to the Main Menu.

Scheduling Heating

Our recommendation is to leave your heating system in comfort mode

instead of setting a scheduling time. The heat pump is designed to produce

and sustain heat throughout the day, compared to traditional heating

systems that emit large volumes of heat at set times of day to heat your

home quickly but ineciently.

Should you wish to set, for example, a nighttime schedule, there are a few

things to consider:

For a night time schedule, we would recommend only reducing the

nighttime temperature by 3°C. For example, if you like your room

temperature to be at 20°C during the day, we would recommend setting

a night time schedule of 17°C. Set this any lower and you may nd your

house is too cold to wake up to!

Also remember, the schedule will tell the system when to initiate the set

temperature, please allow time for the system to reach this temperature.

E.g. if you want your system to revert back to 20°C for 7am, you may wish

to set the schedule to initiate at 6am, to allow the system to achieve your

desired temperature of 20°C by 7am.

throughout the week by selecting “scheduling” in the “HOT WATER” menu. throughout the week by selecting “scheduling” in the “HOT WATER” menu.

N.B Please bear in mind if you set a schedule that any gaps in your schedule

will revert back to comfort mode, and WILL NOTWILL NOT turn the heating o.

For example, if you set a schedule from 08:00 – 17:00, the system would

revert back to comfort mode between the hours 00:00 - 08:00 and 17:00

– 00:00. If you would like set a schedule without the system reverting to

comfort mode, you can activate both Schedules 1 & 2 and set their times

so that every hour in the week is accounted for, and by setting diering

temperatures for Schedule 1 and Schedule 2.

See the next page for an explanation of what each of the labelled elements

refers to.

ScheduleSchedule: You can set two dierent schedules.

ActivatedActivated: a green tick in the white circle indicates the schedule is

activated.

DayDay: Set on and o times for each day. If you do not want a timer to run

for any given day, make sure your start and end times are the same. e.g.

00:00 - 00:00

*Tip*: if you wish to set similar scheduling for each day of the week, start

by lling in ‘all’ (found above ‘mon’ in the diagram) and then making any

desired changes for each day accordingly.

AdjustingAdjusting: set the hot water comfort level to be applied during your

scheduling e.g. smart control / economy / normal / luxury. This will appear

next to the time period.

ConictConict: a red exclamation mark will appear if you select times which

conict with each other, e.g. selecting an end time that occurs before the

start time, such as 01:00 - 00:15.

Disruptions to Comfort & Troubleshooting

If there are disruptions to comfort levels in heating or hot water, there are

some steps you can take that may resolve the issue without needing to

If you require more hot water, please follow steps on p4 to activate

‘temporary lux’. Instructions for adjusting heating temperature are on p3.

Usually, the control module will note a malfunction and will indicate this

with alarms and show instructions of how to rectify it in the display.

Alarm Reset

occured that the heatpump/module cannot remedy itself.

Full Reset

In some cases, e.g. following a power cut and your heat pump has not

recoverred automatically, your system may need a full reset.

To do this, turn the power supply to your indoor unit o.

Next, turn the power supply to your outdoor unit o using the rotary

isolator, which is a switch next to the heat pump and looks like this:
