2.COMPATIBILITY
MyDomo is compatible with most of DOMUSA TEKNIK’s boilers.
MyDomo allows a basic control in analogical boilers, being able to change the boiler
set temperature and at the same time programming different temperatures in diverse
time ranges.
In addition, in boilers with electronic control, the following advanced functions are
added:
Turning on and off the system when demanded.
Changing DHW set temperature.
Adjusting the operation power of the boiler automatically as it approaches to
the desired set temperature.
Getting to know the alarms.
3.RF PAIRING (RADIO FRECUENCY)
Long press light on receiver, green light is on and red light flicks regularly. Then long
press MODE button (MyDomo) to enter coupling state. Displaying “-----” on
transmitter is changed to wireless communication channel (Default channel is 10,
0-19 channels optional). RF icon on transmitter changed from flicking to
constant on means coupling succeeded.

Step 4: Settings.
There are two option to show local weather information in MyDomo:
1. Go to top left menu and go to Account. Input location information (where
MyDomo is being installed) at Weather Location line.
2. Tap in the Outdoor weather temperature and choose the location.

MANUAL MODE: Set the desired temperature by sliding your fingers on screen；
MODO AUTOMÁTICO: Enter programming interface taping in the high right
corner, the below screen appears:
Set the desired temperature and time. Tap the program screen again to set
temperatures and heating time for another period of time in the same day if
needed. If an adjusted program to be copied to another day or set of days, go to
top right corner “APPLY TO” and select the days desired the same operation to
be repeated to.

8
If changes to preset program needed, switch to “MANUAL MODE”, and set per
needs. To go back to the original “PROGRAM MODE”, just switch it back”.
OFF MODE: When set to “OFF MODE”, MyDomo only heats when the room
temperature drops below 5 ºC to prevent frost damage.

9
Before control a DOMUSA TEKNIK boiler with MyDomo, it is necessary to
examine their compatibility with the boiler. Boilers with “Remote Control” option
are compatibles with MyDomo.
Enter “Control my boiler” to see your boiler working state.

5.MYDOMO WI-FI REMOTE CONTROL (TRANSMITTER)
If Wi-Fi connection or the internet is not available, thermostat still work
per previous settings before network cut off, or you can set by
pressing the buttons on MyDomo.
All LED light up for 3 seconds upon powering on, followed by version of built-in
hardware.
①MODE: Press to select “MANUAL MODE”, “PROGRAM MODE” or “OFF
MODE”.
②SET: Press SET to change between room temperature and hour. Press 5
seconds to connect Wi-Fi.
③Knob: Rotate to adjust temperature (valid only in “MANUAL MODE”).
④Room temperature sensor.
⑤RESET: Reboot screen appears after reset button pressed.
⑥&⑦Micro USB port: to supply power.

Icono Descripción / Función
WIFI configuration (WPS) ：Fast double press SET to enter Wi-Fi
configuration, use router WPS function.
Press SET for display the hour. Rotate the knob to set wireless
communication channel (0-19) (default channel is channel 10). Press SET
to validate.
Rotate the knob and press SET to set hysteresis ON value (Range 0-2 ºC
in 0,1 increment). e.g. If target temperature set at 25 ºC and hysteresis ON
temp at 0,5 ºC, when room temperature at 24,5 ºC transmitter sends
heating request signal to boiler. Press SET to validate.
Rotate the knob and press SET to set hysteresis OFF value (Range 0-2 ºC
in 0,1 increment). e.g. If target temperature set at 25 ºC and hysteresis ON
temp at 0,5 ºC, when room temperature at 25,5 ºC transmitter sends
heating off signal to boiler. Press SET to validate.
No functional parameter.
Rotate the knob and press SET to exit current settings.

Factory set defaults:
Hysteresis ON: 0.4 ºC
Hysteresis OFF: 0.4 ºC
Frost protection temperature: 5 ºC
Temperature calibration: MyDomo may indicate a temperature different from the real
one due to its location in the house. After choosing the place of functioning thermostat,
it is useful to calibrate it. Use a precision thermometer near the thermostat that you
keep a minimum of 50 minutes. Press and hold SET and MODE until the temperature
remains on the display only. Enter the thermometer indicated value standard by turning
the wheel on the side of thermostat and press the SET.
Warning: the thermostat does not show correct temperature value and does not allow
calibration in less than 50 minutes after the electrical supply! The temperature is correct
and the device can be calibrated only after the symbol "C grade" goes from small ºc
to big ºC

On RF communication is normal
Radio communication inside the house building structure can be influenced by
many factors (concrete structure, metal objects…). Placing the thermostat in
the control room and the receiver near the boiler must be carried out so that
radio communication to be more stable.

③MANUAL MODE: MyDomo behaves as a simple thermostat. You can adjust
temperature from the side of MyDomo or from App.
④PROGRAM MODE: Check the schedule from the App on your smart
devices.
⑤OFF MODE: MyDomo only heats when the room temperature drops below
5 ºC to prevent frost damage.

6.RECEIVER
The receiver communicates with the transmitter via RF. It mounts near heating device
and is linked to it with electrical connections. Electrical connections will be made by
authorized personnel. Before connection check that the command of the terminals is
NOT 220V!
Receiver – Boiler connection.
1. There are 4 wires from receivers: wires from receiver labelled “OT” are to be
connected with boilers with electronic control. Wires labelled “ON/OFF” are to be
connected with analogical boilers.
2. Use black magnetic pad or the screws to fix the receiver to a proper place.
