How to Use Your Heat Pump Remote Control
This is your quick and simple guide on how to navigate your heat pump remote control so you can
enjoy year-round comfort!
Please note that these instructions only cover the basic heat pump functions. Also, your remote
controller may look different depending on your chosen model with additional functions that are
covered in your user manual.
Operating Modes
Your heat pump can perform in several functions, the main
being the Heating Mode and the Cooling Mode. Other functions
are Auto, Dry, and Fan Mode.
Each time your press the
MODE button a different
operation mode is selected.
The graphic below shows the sequence of the different
operation modes.
The corresponding symbols will be displayed at the top of the
remote control screen.

Winter Heating Mode
STEP 1 – Set Heating Mode
Press the
MODE button and select heating which is
represented by the
(sun) symbol.
STEP 2 – Set Temperature
Press the
(down) and (up) buttons to adjust the
desired temperature.
Optimum Heating Temperature Guide
We recommend 18–22°C for a comfortable environment. If you
prefer your home on the warmer side then we suggest 22°C.
IMPORTANT!
Setting a higher temperature is not going to heat a room quicker.
In fact the heat pump is forced to work harder to achieve this
temperature and is likely to increase power usage!
Summer Cooling Mode
STEP 1 – Set Cooling Mode
Press the
MODE button and select cooling which is
represented by the
(snow flake) symbol.
STEP 2 – Set Temperature
Press the
(down) and (up) buttons to adjust the
desired temperature.
Optimum Cooling Temperature Guide
We recommend 18–20°C for a comfortable environment.
Keep your curtains closed while the heat pump
is in Heating Mode, to ensure that warm air is
retained inside the room.
Auto Mode
In Auto Mode – which is represented by this symbol – the
unit will automatically adjust itself between Heating and Cooling
Mode to maintain the set temperature.
Controlling the Airflow
Adjusting the Fan Speed
Press the
FAN button repeatedly to select the appropriate
fan speed level. To heat or cool a room more quickly, select a
higher fan speed.
A fan speed of 1 or 2 (LOW or MEDIUM) is ideal to keep a
consistent environment.
Setting a lower fan speed offers a more gentle
heating or cooling effect.
Rather than using the Auto Mode we
recommend using either the Heating
or
Cooling
Mode based on the season.
To heat or cool more quickly select a higher
fan speed.
Auto Fan Speed
Selecting Auto Fan Speed (represented by the
symbol)
means that you no longer have to worry about which fan speed
is best suited to any particular time of the day.
The fan speed will automatically adjust to quickly get the room
to the set temperature (3 or 4 bars) and then drops back (1 or 2
bars) to maintain the room temperature.

How to set a Daily Timer to Turn
Your Heat Pump on at a Specific
Time
When you go to bed at night, instead of turning the unit off with
the
ON/OFF power button, press the TIMER ON
button.
Now you can select the time that you would like the unit to turn
on in the morning by using the
up and down arrow
buttons.
In the example on the right the heat pump is set to turn on at
8:30 in the morning.
You can do this again during the day if you are going out and
would like the unit to turn on before you arrive home.
Using the Daily Timer function will require you to do this each
day as it is a 24 hour timer only.
Press to SET START TIME
Press
to INCREASE or to DECREASE start
time by 10 minutes
Press to SET STOP TIME
Press
to INCREASE or to DECREASE stop
time by 10 minutes
IMPORTANT!
Your remote controller will need to be set with the correct time
and day for the Daily Timer function to operate.
Please remember that the time shown is in a 24 hour format and
does not indicate AM and PM.
It is likely that your installer would have set the correct time on
your controller, but if you have any problems please call our
Customer Service Team on 0800 784 382.
The Weekly Timer
Your remote controller also features a Weekly Timer function which allows you to set up to four start
and stop times for each day of the week.
For more information on how to set the Weekly Timer, please refer to your user manual, visit
our website or please call our Customer Service Team on 0800 784 382.

Frequently Asked Questions
How do I know if my room has reached the
set temperature?
Our Mitsubishi Electric Heat Pumps have two indicator lights on
the bottom right corner of the indoor unit that are connected up
to a built-in indoor temperature sensor.
These two indicator lights will tell you the temperature status of
your heat pump.
Two green lights
This indicates that your heat pump has not yet reached the
set temperature and the system is working to heat or cool
your room.
The indoor temperature sensors are intuitive and will identify
temperature drops or increases over 2°C from the set
temperature of your heat pump.
As a result the fan speed will automatically increase to start
heating or cooling the room until the set temperature is reached.
One green light
This indicates that the heat pump is within 2°C of your set
temperature. As a result the fan speed will automatically reduce
in order to keep airflow circulating in the room.
My heat pump has reached the set
temperature but it looks like it is still running
Our Mitsubishi Electric Heat Pumps utilise inverter technology,
which means they intuitively increase or decrease operation to
achieve your desired temperature.
Heat pumps with old technology (fixed speed systems) used
to turn on and off like an electric heater, which meant that
increased amounts of power were required during this action.
Non-Inverter Heat Pump
Continuously switching
between sprinting and
resting wastes more energy.
Inverter Heat Pump
Maintaining a steady
pace and making small
adjustments is more
energy-efficient.

When your heat pump has reached the set temperature, it will
ramp down but continue to circulate the room air. It is important
that it does this as it aids in better heat distribution throughout
your whole room; improving air circulation and enabling the
system to correctly sense the whole room temperature.
The air being circulated by the heat pump may not feel
very warm (when the system is in Heating Mode) as it is
not producing heat. The air will be at room temperature so
may feel cooler than the air you feel while the system is in
heating operation.
Rest assured, when the heat pump senses a drop or increase in
room temperature, it will begin to heat or cool again depending
on the mode selected.
If I turn my heat pump up to 28°C will it heat
the room faster?
A heat pump should not be operated like a radiant heater.
Turning your heat pump up to 28°C will not make the room
warm up any faster. In fact, it will use more energy as the heat
pump attempts to absorb energy to achieve this unrealistic
temperature.
By setting the temperature to what is actually required, the heat
pump will respond in the most efficient way and will reach this
temperature quickly and continue to maintain it – without any
further adjustment.
We recommend a temperature between 18–22°C for a
comfortable environment. If you prefer your home on the warmer
side in winter then we suggest 22°C.
Should I use my heat pump 24 hours a day?
This really depends on your lifestyle and health requirements.
If you are at home for most of the day, then you may choose to
run your heat pump at a constant temperature on heating, say
about 18–22°C, so that you are always comfortable during the
day. When you are ready to go to bed, you can then choose to
turn the heat pump off.
Heat pumps are clever and will sense when the room is naturally
warmed by the sun and will stop heating if not required.
The heat pump will then start heating again automatically if the
room temperature falls.
You can see this by looking at the 2 heat pump indicator lights
on the front of your heat pump.

Should I leave my heat pump running
overnight?
This is very much a personal preference.
But, while sleeping, your body does not have the same sort of
temperature requirements as it does during the day.
If you like your environment to stay nice and warm then you
could run the heat pump overnight at a lower temperature than
you would run it during the day for example between 16–18°C.
Reducing the temperature before you go to sleep at night will
ensure that you are not using excessive power to maintain a
high temperature that you are not awake to enjoy.
Should I leave my heat pump on if I leave
home during the day?
If you are going to be out for a few hours or most of the day,
then it is more economical to turn your heat pump off so you are
not heating an unoccupied space.
On a sunny day this means that the unit will be utilising the
warmth that is already in the house from the sun, and it will not
have to heat the room up from a much lower temperature.
Alternatively you could use the timer on the
heat pump to have it turn on 30 minutes before
you normally wake up in the morning, so that
the room is toasty warm for you when you get
out of bed.
We suggest that you use the Timer function to
have the heat pump turn on around the time
you lose the sun or 30 minutes before you are
expected to return home.
9
Should I pre-cool or not?
Pre-cooling a room is not recommended. With summer cooling
we recommend you use the heat pump only when you feel too
warm and for shorter periods of time.
This will ensure that you are not experiencing larger than desired
power bills whilst maintaining comfort levels.
Does a heat pump prevent condensation?
The simple answer is no.
While a heat pump’s primary purpose is to heat or cool your
room, our heat pumps offer limited dehumidification in Dry Mode.
It is important to note that when the heat pump is operating in
Dry Mode, the unit is not heating, so it is recommended to only
use the Dry Mode for shorter periods of time and when heating
is not required.
While good airflow does help to prevent moisture build up,
specialised moisture control products such as the Mitsubishi
Electric Lossnay Home Ventilation System or a Mitsubishi Electric
Oasis Dehumidifier may be required to specifically address
excess moisture concerns and assist with fresh air ventilation.
What is Defrost Mode?
All heat pumps will from time to time perform a defrost cycle
when operating in cold winter conditions.
This is normal to remove ice build up from the outdoor unit.
In Defrost Mode the heat pump stops heating for short periods.
Some heat pump brands spend longer in defrost than others.
This is part of what makes Mitsubishi Electric Heat Pumps
so efficient.
With a Mitsubishi Electric Heat Pump you get more heat and less
defrost cycles, which means less overall power usage and higher
energy efficiency.

Heat Pump Maintenance
Cleaning your heat pump regularly ensures optimum operation by reducing unnecessary power
consumption; increasing energy efficiency and limiting exposure to condensation.
Indoor Unit
We recommend cleaning your heat pump filters with every seasonal change. You can do this
yourself by using a domestic vacuum cleaner with a small brush attachment.
Should you encounter any issue with your heat pump, please contact us.
Call Customer Service on 0800 784 382
or visit www.mitsubishi-electric.co.nz/support for additional support documentation.
If you prefer you can organise a service company to regularly clean and service
your heat pump indoor and outdoor unit for you. Please contact our Customer
Service Team on 0800 784 382 for assistance.
Outdoor Unit
We recommend cleaning your outdoor unit every 6 months.
You can do this yourself by clearing any rubbish, plant matter or
debris from around the unit. Wash the outdoor unit and coil with
a detergent (car wash liquid is ideal, do not use other detergent
i.e. dish washing liquid) and hose down afterwards.
It is also important that you do not place any outdoor furniture,
plants or ornaments on or around your outdoor unit. Anything
that compromises the airflow around the outdoor unit will
compromise its performance.
