OPERATING GUIDE
Connecting Thermostat to Android or iPhone App
- You will need a 4G or 5G mobile phone and a wireless router.
- Download the “Smart RM” app from Google Play (Android users) or the App Store (iPhone users).
- If you cannot find “Smart RM” or already have a “Smart Life” app the thermostat can also be used with this.
If you are intending to use the thermostat with your mobile phone, we recommend you set up the app as soon as possible. Adjusting the settings of the thermostat is much quicker using your phone’s display and buttons. Most settings are available on the app. The time and day number are automatically sent from the app once paired. Instructions for pairing your phone to the app are included but if you require a digital version or the latest update, just scan the correct QR code below for your phone type.

INSTALLATION
The OUH3-WiFi thermostat can be used with its internal air sensor or if
required with an optional remote air sensor or optional remote black bulb
sensor.
CHOOSING A LOCATION FOR YOUR OUH3-WiFi CONTROLLER OR REMOTE SENSOR
The OUH3-WiFi controller or sensors should be mounted on an internal wall of
approximately 1.5 meters from floor level and should be in a position away
from draughts, direct heat and sunlight. If you decide to use remote sensors
you will need to change “BN” to “N2” on the advanced default settings. See
page 8 for more information.
INSTALLING THE OUH3-WiFi CONTROLLER
- Decide if it is easier to drill holes for cable glands or conduit in the enclosure before mounting to the wall.
- Screw the OUH3-WiFi in position using suitable fixtures and fittings allowing space to the right to access the control switch.
- There are 4 holes in the corners of the case, or you can drill additional holes in the back below the circuit board.
- Wire the controller as per the picture above, making sure all the terminals are done up tightly.
- If you are using a remote sensor connect to terminals 5 and 6 (marked NTC). These are positioned on the thermostat mounted on the front cover.
- You can use any insulated copper wire.
- The polarity of the sensor does not matter. (you will also need to change the default settings to activate the remote sensor see page 8).
- Please also read the heater instructions regarding connection as it gives details on wire sizes etc.
SWITCH MODES
The switch on the right-hand side of the controller has the following modes:
OFF – When in this position both the fan and the heat are turned off. Please
Note:- Should you have a frost thermostat fitted to the heater it will still
operate even with this switch in the off position.
FAN – When in this position the fan will operate regardless of the thermostat
settings. Useful in the summer for moving air around.
HEAT – When in this position the heater will turn on and start warming up the
building BUT only when the thermostat is asking for heat. It will not override
the thermostat settings.
CHANGING THE MASTER / DEFAULT SETTINGS
Various master/default settings can be changed by entering the default
settings. To enter these settings, turn off the thermostat by pressing the
button. Now press the screen in the touch-sensitive area until all the buttons
light up. Then press and hold the button for 3-5 seconds until the A1 appears
on the screen. You are now in settings mode and if you don’t press any button
for 5 seconds the display reverts to off mode. Press the button to switch to
the next option and press or buttons to adjust the data. If you wish to exit
the settings without waiting 5 seconds press the button.

USING AS A CONVENTIONAL THERMOSTAT
It is easy to set up your WiFi thermostat to operate as a simple, conventional
thermostat without the need to program different times and temperatures. There
are 2 steps.
- Set the temperature required – Refer to “Run Modes” on page 3 and use manual mode, then select the required temperature by using the or buttons.
- Lock the thermostat – Refer to “Locking the controller” on page 3. Locking the thermostat will disable all the buttons except the on/off button.
- If you want to disable the on/off button as well, you will need to change the default lock settings before starting this process (see section 5).
SENSOR FAULT CODES.
E1 or E2 fault codes are displayed if the sensors are faulty or are not connected. The thermostat will stop heating until the fault is corrected. E1 = Internal sensor faulty. E2 = External sensor faulty or not present.
If in the advanced default settings shown above, you have selected N3 for option BN (Sensors used) you will get a fault code and the thermostat will not work, please select either N1 if you are using the internal sensor or N2 if you are using an externally mounted sensor
