What Combi
Control does?

Combi Control is a heat pump controller you operate
with a mobile phone. It is compatible with most
popular Toshiba heat pumps and all mobile phones (see
CombiControl.eu for the complete list).

The easiest way to use Combi Control is with a
Smartphone, using the Combi Control app downloadable
from the Android Market (for Android phones ) or App
Store (for iPhone). It can also be controlled with regular
mobile phone text messages (SMS). Combi Control allows
you to have long distance control over the mode of the
pump, room temperature and fan speed settings. Combi
Control can also inform you about low room temperature,
power failures and heat pump service intervals.

Indicator lights

The controller has 3 LED indicators and 2 buttons for
easy setup. It has also 2 infrared LEDs that transmit your
commands to the heat pump.

battery

The controller has a battery that keeps it operational even
if it’s disconnected from a wall outlet. To fully turn o the
controller, push the RESET button. The 3 LED lights will
blink for about a second and the controller switches o.

Use this button also to clear the most recent settings (the
Owner number will remain unchanged).

TEST button

Short push turns the heat pump ON/OFF

Use the TEST button to conrm that the IR beam from the
controller reaches the heat pump.

RESET button

Power

When the power is out (power = 0V) the controller
continues to work on the battery and turns o after the
battery’s voltage drops below 3.5V. A fresh battery lasts
for approximately 24 hours (note that over time the
battery’s capacity decreases). After the controller is turned
o the run time will be saved. To save battery life when
the power is out the controller can be turned o with a
short push on the RESET button.

SIM card

NB! Make sure you disable the PIN code of the SIM card
you use in Combi Control.

NB! Make sure the SIM card you use in Combi Control can
access 2G network. Combi Control is not compatible with
SIM cards that use only 3G network.

A) Make sure that you have previously disabled the SIM card PIN code.
Insert SIM card as shown into Combi Control.
B) Plug the adapter into the socket under the Combi Control.

Installing
Combi Control

Combi Control should be mounted on the wall to the right
of your heat pump’s indoor unit (see g. 1), with its IR
transmitter pointing down. This way
the IR beam is reected from the oor and reaches the heat
pump’s sensor most eciently.

Other mounting congurations are possible too
as long as IR transmission from the controller
to the pump works.

NB! Thick carpets and dark oors can distort the IR beam.

Make sure the IR beam reaches the pump’s sensor by using
the controller’s Test function (see page 19).

Testing Combi
Control

To see if Combi Control can send commands to your
heat pump, turn o the pump and press the controller’s
TEST button. When the connection is established, Combi
Control turns the pump on with its last settings and you
can proceed using the controller.

Commands

The range of heat pump temperature values Combi
Control controls is 16-30 °C (default +20 °C) and the fan
speeds are MIN, NORM, MAX
(the default is NORM).

After selecting a mode (AUTO, DRY, COOL, HEAT, T8, T10)
heat pump is turned on with 20 °C maximum temperature
and normal fan speed, if not assigned dierently by the
Owner or the Users (see pages 24 and 29 for how to set
the Owner and Users).

The pump can be assigned dierent temperature and fan
speed values with Combi Control.
For example, the SMS: “COOL 19 MAX” orders the pump
to cool until 19 °C and fan at maximum speed. When
you change a heat pump function Combi Control always
responds with an SMS that reports its STATUS (see page 39
for full STATUS report explanation).

User levels

The amount of control Combi Control users have over the
device and the amount of information they receive from
the device can be set on a 3 level scale:

1. The Owner can send commands, report queries, setup
commands and receive Combi Control report messages
and alarm messages.

2. The Users can send commands and report queries to
Combi Control but cannot send Setup commands.

3. The All-level users can make report queries about the
status of the controller.

26 27

Owner setup

Setup can only be performed by the Owner. When no
Owner has been previously set, Owner number can be
sent from any mobile phone number. There are 2 ways
to do this:

The to-be Owner sends the SMS “93” to the controller. The
SMS containing “93” followed
by the mobile number of the to-be Owner –
e.g. “935012345”– is sent from any mobile phone.

The Owner number can be international (with the “+”
symbol and country code) or local. The length of the
number must be between 3 -16 symbols (“+” counts as
1 symbol).

Successful Owner number entry/Owner number change
is conrmed by “VERSION” report SMS sent to the new
Owner (see page 40 for full “VERSION” repor t explanation).

After Owner number has been set up, setup can be done
from this Owner number. All other numbers attempting

to change setup will be ignored. When no Owner number

has been entered all numbers have Owner rights (all
numbers can assign themselves as owners and no alarm
messages will be sent). When the Owner has not set User

numbers, all numbers have User rights.

Should you suspect Combi Control could be controlled
from unapproved numbers, we recommend you set the
Owner and User numbers.

Owner number
reset

Once set, Owner number can be reset via mobile phone
only by the Owner himself or by performing a hard reset
by pushing both controller hidden buttons simultaneously
for 3 seconds (hard reset can also be used when a wrong
Owner number is entered by mistake).

Setup reset

For setup reset send the SMS “90” to the controller. Combi Control responds with SETUP
report:

“Owner: All; Users: All; Pump: All; Ring 2,2,2; Param: 5, 24, 180”.

This means Owner is not specied; all users can send commands;
the pump model is not specied, call commands are set to default;
“LOW TEMPERATURE” message will be sent when room temperature drops below 5 °C ,
“NO POWER” message blackout is in 24 hours and the “SERVICE” alarm message interval
is 180 days.

User setup

To set User numbers start your command SMS with “91”, followed by the mobile phone
number of the User. For example: “91+495012345” or “915012345” to enter User1
number where “5012345” is the cell phone number of User1 and +49 is the country
code. User numbers (Owner, User1, User2) can be international (with the “+” symbol and
country code) or local. The length of the number must be between 3-16 symbols
(“+” counts as one symbol). Multiple commands can be combined into one SMS. When a
User has been set, Combi Control responds with a SETUP report message.

91xx* User1 number entry (to delete: 910)

92xx* User2 number entry (to delete: 920)

93xx* Owner number entry (to delete: 930)

*xx marks the place of mobile phone number

32 33

Multiple commands

If you want to set up several parameters with one SMS, separate commands with one of the
following:

space
comma “,”
semicolon “;”

For example, the SMS „91+ 49550111111 92+49550222222 9522 9720”
sets the User1 and User2 numbers, species the heat pump model as “Toshiba Daiseikai 5”,
and determines that NO POWER message will not be sent in case of a power failure.

When a command in the multi-setup is incorrect, the Owner will receive an error message.
All the correct commands that precede the error command in the multi-setup command
will be activated.

Multi-setup sender will always receive SETUP report SMS from Combi Control to conrm
that all commands arrived to the controller. There can be spaces before and after a
command but not inside a command as this will interfere with the code.

Heat pump model setup

The pump can be chosen on 3 levels of precision:

1. The precise name of the pump: the manufacturer and the model.
This is recommended for the most ecient operation.

2. Pump manufacturer.

If you only choose the pump manufacturer, functions T8 will not be checked and the
command will be sent even if the pump does not have
T8 mode. If the exact pump model is not listed on our webpage or in this manual,
Combi Control may or may not work with the heat pump, for which the Combi Control
manufacturer will not be held responsible.

3. All pump models.

If you choose All pump models (SMS: “950”), then all supported brands IR commands will
be sent to the pump, and Combi Control can be used without choosing the pump more
precisely.

Alarm messages setup

The Owner can change the default values of the conditions on which alarm messages
are sent. For example, SMS “9713” lowers the room temperature value at which “LOW

38 39

Error messages

“Error command: text”
SMS will be sent if there was an error in your command.

For example, an SMS “cool19max” receives the response
“Error command: cool19max”. Note that Combi Control will only return your incorrect
command without suggesting a correct one (the error in the example is the absence of
spaces between commands).

“Error userrights: text”
SMS will be sent if the user had no rights for that command.

“Error pump command: text“
SMS means the operation T8 is not available for the specied pump.

When Combi Control fails to send an SMS it will retry after 1 minute.
