OPERATING GUIDE

Connecting Thermostat to Android or iPhone App

• You will need a 4G / 5G mobile phone and wireless router.
• Download “Smart RM” app from Google Play (Android users) or the App Store (iPhone users).

INSTALLATION.

CHOOSING A LOCATION FOR YOUR W16C
The W16C 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 W16C
The thermostat requires a one gang back box having a  minimum depth of 35mm.

• Remove the front screen from the back of the thermostat by turning over so it looks like picture A. Now with your fingers holding the white front screen gently push the back down using your thumbs. The black metal plate and the wire connection block should move together and end up like picture B.
• The back and front will now gently pull apart (NO FORCE REQUIRED) exposing the connecting plug and cable. Gently remove the plug and cable from the back of the front screen. You will now have two parts looking similar to picture C below.
• Wire the thermostat as per wiring diagram to the right making sure all the terminals are done up tightly. An underfloor sensor (supplied) must be used, 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. Loads greater than 16A should be controlled via a suitably rated contactor or relay box.
• 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 1 to the right.
• Slide down the front screen until it nclips into position. See picture 3 to the right.
• Reconnect lead to the front screen.
