IMPORTANT INFORMATION: Installation should only be carried
out by a qualied and competent electrician and must conform
to local electrical code. Conduits are only required where it
is mandated by state or provincial code. Please refer to local
electrical code for compliant applications.
The 4iE and its power supply should be isolated from
the mains supply throughout the installation process.

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. heater 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.

Master/relay function: Used to control loads greater than 15A.
Heaters will be split across two 4iE’s, one being the master and
the other being the relay (slave). Only one oor sensor is required,
wired into terminals 1 & 2 of the Master 4iE.
Wiring Connections: Use low voltage electrical cables to link
terminals 2 & 3 of the Master and Relay.

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.
During the initial setup step 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
4iE
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 68°F and 86°F 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”.
(Air Mode only suitable for tiled oors if oor sensor has
been damaged)
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 81°F.

GFCI Notice
The GFCI feature is used to detect any leakage of current from your heating
system. During a ground fault the two lines of the load will be cut o. Once
your thermostat is installed and connected to a power supply you can test
the GFCI function by increasing the set temperature until heating is on - the
heating up icon ( ) will be illuminated - and pressing the “TEST” button.
If your test is successful you will see the GROUND FAULT screen and you will
need to hold “cancel” for 3 seconds in order to restore heating operation.
However if the thermostat detects that one of the relays has FAILED to open
correctly you will see the CONTROL FAULT screen and the TEST LED will
illuminate. In the following circumstances you should immediately isolate
the power supply to the thermostat and contact our helpline:
1. Press the TEST button when heating is on (heating icon ( ) will be
illuminated) and the screen does not display GROUND FAULT or cut power to
the load.
2. The thermostat shows the GROUND FAULT screen during normal operation.
3. The thermostat shows the CONTROL FAULT screen.
Note: The GFCI test should be carried out monthly.
