eFlex and Floor Sensor

1st Step

2nd Step

Electrical Requirements

Before installing the eFlex you should make allowance for the electrical connections.    
The eFlex system requires a mains voltage 230/240V and must be connected in 

accordance with the current IEE regulations and building regulations part ‘P’ approved 

document.
For areas up to

 3450W 

power connection can be provided through a 13A switched 

spur outlet/combined RCD spur outlet. For larger areas a dedicated circuit should be 

installed from the local consumer unit.

Confirm your thermostat is suitable to switch the appropriate electrical 
load e.g. 16A thermostat is suitable to switch up to 3450W total load.

If you are required to switch greater electrical load than 16A a suitably sized 
thermostat or electrical contactor MUST BE INSTALLED. Please consult our 
Help Line if in doubt 08714 740 818.

We recommend that all eFlex systems are protected by a 30ma RCD earth trip either 
at the consumer unit or by a combined RCD spur outlet.
When installing in a bathroom or other wet areas the thermostat must be located 

outside Zone 2 (600mm from any wet appliance e.g. shower sink etc) or outside of the 
wet area ideally on the opposite face of the wall. The eFlex must be earth bonded in 

accordance with the current IEE regulations.

Important. When designing your electrical installation you should always 
consult an electrician concerning your requirements.

Please follow these instructions carefully. If you require assistance prior to 
or during your installation please call our helpline on 08714 740 818
