INSTALLATION

CHOOSING A LOCATION FOR YOUR B16C

• The B16C controller 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.

INSTALLING THE B16C

• The thermostat requires a one gang back box having a minimum depth of 35mm.

1. Remove the front screen from the thermostat by gently using a screwdriver underneath the front lip to release the two plastic clips. Gently pull the screen towards you releasing the internal plug which allows the two parts to be separated.
2. Now remove the plastic centre housing from the back plate by gently lifting in the direction shown in the picture. Once lifted gently pull towards you exposing the black metal back plate.
3. Wire the thermostat as per picture 1 making sure all the terminals are done up tightly. An under floor sensor must be used (supplied) and this MUST only be wired to terminals 5 and 6. Polarity of the sensor does not matter. Do NOT exceed total load of 16A. For loads greater than this, use a contactor with the thermostat controlling the coil of the contactor.
4. Once all the connections have been made, make sure the arrow on the back plate faces upwards and secure to the back box using two screws. See picture 2 to the right.
5. Slide on the centre housing until it clips into position. See picture 3 above.
6. Finally push the plug into the socket on the front screen and clip onto the centre housing.
   • Note:– The plug only fits one way around so don’t force it.

CHANGING THE MASTER / DEFAULT SETTINGS

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 button. 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 back to off mode. Press button to switch to next option and press or buttons to adjust the data. If you wish to exit the settings without waiting 5 seconds press the button.

BATTERY REPLACEMENT

The thermostat contains an internal battery that maintains the settings should you have a power failure. If you find the settings are not remembered after a power cut, the battery needs replacing.

• Before replacing the battery, ensure the mains power is completely turned off and isolated.

1. Remove the front screen panel as per instruction.
2. Disconnect the plug connecting the front screen to the back of the controller.
3. Replace the battery with another ensuring polarity is correct.
4. Dispose of the old battery correctly.
5. Reassemble is reversal of above.

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.
• If in the master settings shown overleaf, you have selected N3 for option A4 (Sensors used) you MUST have a floor sensor present and working otherwise the display will show fault code E2 and will not work.
