Connecting Thermostat to Android or iPhone App
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 phones 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.

To Set Time and Week Day Number
Programming – The controller is pre-set to the following times and temperatures:-
By default, the controller is set to 5+2 days. This means when programming Monday – Friday settings will all be the same and you can then program different settings for Saturday – Sunday. If you require 7 day or 6+1 day settings, go to “default settings” and adjust parameters first (See section 5).

INSTALLATION SAFETY INSTRUCTIONS
ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the installer to read, understand and comply with the following: You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. If in any doubt consult a qualified electrician. You must also read and understand the following instructions concerning electrical safety.
GENERAL SAFETY INSTRUCTIONS
The WT26 thermostat can be used with its internal air sensor or if required with an optional remote air sensor or optional remote black bulb sensor. Sensors are wired to terminals 5 and 6. Polarity of the sensor wires does not matter.
CHOOSING A LOCATION FOR YOUR WT26 OR REMOTE SENSOR
The WT26 controller or sensors should be mounted on an internal wall 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 advance default settings. See page 8 for more information.
INSTALLING THE WT26
Screw the WT26 in position using suitable fixtures and fittings.
There are 4 holes in the corners of the case, or you can drill additional holes in the back.
There are various master / default settings that can be changed by entering the default settings. To enter these settings, turn off the thermostat by pressing the

USING AS A CONVENTIONAL THERMOSTAT
It is easy to set up your WT26 thermostat to operate as a simple, conventional thermostat without the need to programme different times and temperatures. There are 2 steps.
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 advance 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 external mounted sensor.
