OPERATING GUIDE

Connecting Thermostat to Android or iPhone App

1. You will need a 4G or 5G mobile phone and wireless router.
2. Download “Smart RM” app from Google Play (Android users) or the App Store (iPhone  users).
3. If you cannot find “Smart RM” or already have “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 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.

CHOOSING A LOCATION FOR YOUR WT16 OR REMOTE SENSOR
The WT16 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 WT16
Screw the WT16 in position using suitable fixtures and fittings.
There are pre-drilled holes in the back of the case, or you can drill additional holes in required.

1. Wire the thermostat as per picture to the right and below making sure all the terminals are done up tightly.
2. If you are using a remote sensor connect to terminals 5 and 6 (marked NTC) of the thermostat using any insulated copper wire. Polarity of the sensor does not matter. (you will also need to change the default settings to activate the remote sensor see page 7).
3. Do NOT exceed total load of 16A. For loads greater than this, use an additional relay box (RB26) or contactor. If using a contactor, the thermostat must only control the coil of the contactor.

USING AS A CONVENTIONAL THERMOSTAT

It is easy to set up your WT16 thermostat to operate as a simple, conventional thermostat without the need to programme different times and temperatures. There are 2 steps.

1. 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.
2. 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 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.
