5

Electrical Information  

All electrical work must be  carried out by a certified electrician.  All work must 

confirm to current IEE wiring regulations - BS 7671:2008. A certified electrician 

must sign off the final installation.

Installing an RCD

The electrician 

must

 install a dedicated 30mA RCD.  A combination “double pole 

fused switch/spur must incorparated in order to isolate the system.  

Ensure that all earth connections from the heating panel are connected to the 

protective conductor of the supply circuit. 

Electrical accessories needed

• Electrical Back Box - A 35mm back box may be used for the all Warmup 

thermostats. 

• Junction Box - If installing more than two heaters a junction box will be required.

• Conduit or plastic trunking- The wiring to the thermostat should be chased into 

the wall protected by conduit or plastic trunking. 

Connecting the thermostat 

The Warmup wall panels must be controlled via a thermostat using an external 

temperature sensor at all times to ensure that the maximum temperature of 40°C 

is not exceeded. The thermostat must be connected to the mains electrical sup-

ply via a double pole isolator fused spur or RCD that has a contact separation in all 

poles providing full disconnection under over-voltage category III conditions .The 

thermostat is IP20 rated and must be located outside of Zone 2 in wet areas. 

If floor heating is also installed the system 

must 

be controlled via a separate 

thermostat and temperature sensor.

Temperature Sensor Location 

The thermostat must always be operated 

using the 3m external temperature sensor 

supplied with the Warmup Thermostat. The 

sensor must be placed centre of two of the 

heating element runs of the heating panel. 

The sensor must not cross over or touch any 

of the heating wires. When connecting to the 

thermostat ensure that the wire is installed in 

a separate conduit to the heating panel cold 

lead to avoid any electrical interference.
