IMPORTANT INFORMATION: Installation should only be carried
out by a qualied and competent electrician. The 4iE requires
a permanent 230V supply from a 30mA RCD protected circuit
in accordance with the current edition of the BS7671 Wiring
Regulations.
The 4iE and its power supply should be isolated from the mains
supply throughout the installation process. Ensure that wires are
fully inserted into the terminals and secured. Any free strands
should be trimmed, as they could otherwise cause a short-circuit.
Electrical installation to be in accordance with latest
edition of BS7671 Wiring Regulations

Before making any permanent xtures Warmup recommends
identifying your preferred location for the 4iE. It should be
located in an area with good ventilation. It should not be beside a
window/door, in direct sunlight or above another heat generating
device (e.g. radiator or TV).
Ensure the distance from your router to the 4iE is not too great.
This will ensure the wireless connection is not subject to range or
interference issues once installed.
BATHROOM INSTALLATIONS: When installing a 4iE within a
bathroom it MUST be mounted outside of Zone 2 in accordance
with the Wiring Regulations. If it is not possible to identify a
suitable location outside of Zone 2 within the bathroom, then it
is recommended that the 4iE is installed in the adjacent room
and set to control the heating by oor temperature only. When
installed in this way, it is not possible to directly control the
heating based on the room air temperature, only the oor surface
temperature.

Step 6 - Registering your device
Location
A location needs to be setup before a room can be congured and
the 4iE device registered. Creating a location is user friendly and
easy to follow, it is advised to have details of your current energy
tari and pricing to hand, as these will be required for the energy
monitoring features.
Room
With a location now setup, the next step is to register a room.
When creating a new room, the following options are available to
select:
Location (Select the newly setup location)
Room name (Description, e.g. Upstairs Bathroom)
Room type (Select the room type e.g. Bathroom)
Floor type (Select the oor type e.g. Tile/
stone)
Device number (See page 9)
System type (Select e.g. ’Electric Underoor’
System power (Size of heat source e.g.1000W)
Power source (Energy source e.g. gas/electricity)
Registration
Once the App has been successfully downloaded and device
number recorded you will need to set up your MyWarmup account.
The Thermostat can be registered via the MyHeating App or by
visiting my.warmup.com

Once setup has been completed the thermostat will display the
home screen. If you do not press any button for 1 minute the 4iE
screen will dim and go into standby. To wake the 4iE just tap the
screen or press the lock icon.
Press the button on the bottom of the device to put the
thermostat in/out of standby mode. Hold the button for 3 seconds
to turn the heating o.
The icons at the bottom of the screen are your WarmApps. These

Energy Monitoring
The 4iE learns how you use your system and how your house reacts
to the heating and weather. It can give you an estimate of your
energy usage and the running cost of your system.
On initial set up, Step 5, you will have entered the power
(wattage) of your system and the cost per kilowatt hour charged
by your energy provider. The 4iE will use this information to
calculate the running cost of your system.
When you’ve set up the Energy Monitor you can view the
estimated usage or cost over a selected time period. If you have
a standard/low energy tari, the amount and cost of energy used
during the standard period will be displayed in dark green and the
amount used in the low period will be displayed in light green.

Troubleshooting
1. Check that the display/standby brightness is not on
the lowest settings ‘0’.
2. (Electrician Required) Electrician required to verify
power is going to the 4iE and that it is correctly wired.
1. (Electrician Required) Electrician required to verify
that the oor sensor has been wired correctly. If it is
correctly wired the electrician will need to check the
resistance of the oor sensor using a multi meter. For
temperatures between 20°C and 30°C the resistance of
the oor sensor should measure between 8K ohms and
12K ohms.
If the electrician nds a fault, and the 4iE is in the
room to be heated then it can be set into “Air Mode”.
1. The 4iE “Early Start” function is on. This means
that the heating will come on early to achieve the set
temperature at the set time.
1. Delicate oor coverings need to have their
temperatures limited. If the nished oor is set for
wood, laminate, vinyl etc. you are unable to set the
temperature above 27°C.
