Installation Guide:
for the Warmup 3iE Programmable Thermostat
3iE Installation Guide V5 © Warmup plc - 2015
Introduction:
The 3iE thermostat is designed to aid in the comfort of your home by providing timed regulation of your Warmup underoor
heating system. The thermostat is designed to receive temperature input signals from the following sensors:
1. Air sensor located inside thermostat
2. Floor sensor installed in oor to be heated (see Warmup heater instructions for details)
3. Optional 2nd sensor (either installed in oor or outside house)
The thermostat is not a safety device and should only be used with Warmup heating products. In order to avoid damaging
your ooring the correct oor type should be selected during the thermostat programming process.
Electrical Specication:
• Supply voltage: 230V +/-15% at 50Hz
• Thermostat is not designed for use with intermittent power supply.
• Maximum Switch Load: 16A resistive
• Insulation Class : II
• Housing : IP20 (IP32 when used with gasket- see tting instructions)
• Standards: EN60730-1 & EN60730-2-9 standards
WARNING – Important safety note
This product uses mains voltage electricity and work should only be carried out by a qualied electrician. You should always
isolate the power supply before attempting to install or repair the 3iE thermostat. The thermostat should not be put into
operation unless you are certain that the entire heating installation complies with current general safety requirements for
electrical installations. Electrical installation to be in accordance with latest IEE Wiring Regulations and appropriate Statutory
Regulations.
Location of Thermostat:
The thermostat should be installed inside a single gang electrical wall box that is at least 35mm deep. For optimal
performance the thermostat should be located in an area with good ventilation. It should not be beside a drafty window/
door, in direct sunlight or above another heat generating device (e.g. radiator or TV).
In most bathroom installations the thermostat cannot be located within the bathroom itself as the thermostat is IP20 rated
and must be located outside of Zone 2. In such cases the thermostat must be tted to the outside of an internal wall of the
bathroom using the oor sensor to regulate the temperature.
The thermostat is designed for operation between 0°C and 55°C with relative humidity less than 80%.
Location and installation of oor sensor:
The optimum location of the oor sensor is described in each Warmup heater installation manual. Refer to that manual when
selecting oor sensor location.
The oor sensor provided with the 3iE thermostat enables accurate temperature control of the oor heating system. Floor
sensors are required to regulate electric underoor heating systems. It is recommended that oor sensors are also tted with
hydronic underoor heating systems, providing improved oor temperature control.
The oor sensor must be at least 300mm from the wall and should be placed centre of two heating element runs.
When positioning the oor sensor avoid placing the sensor in areas where it may be exposed to sunlight or draughts. Avoid
areas where there are hot water pipes that may aect the temperature reading.
As the warranty does not cover the oor, it is recommended that the oor sensor is installed into a non-conductive conduit.
This will allow for easy replacement of sensor after the ooring has been laid.
Make sure the conduit has a gradual bend when it enters oor, this will ensure the sensor cable can be easily inserted or with-
drawn. Seal the end with tape to prevent adhesive/screed from entering the conduit.
Route the conduit to the connection box. The end of the conduit should be easily accessible after the ooring has been xed.
Warning: Do not attempt to cut conduit with sensor installed. This could lead to irreparable damage to your sensor.
- Installed in oor: This is to be used if the oor surface area is very large and delicate to overheating. The reading
from this secondary oor sensor will be used to monitor the overheat limit.
- Installed outside house: The 2nd oor sensor will engage weather compensation. Weather compensation saves
energy by delaying the start of heating period by 10 minutes if the dierence between internal and external
temperature is less than 5°C.

Installation:
Separate the front housing of thermostat from wall module:
1. Unscrew both closing screws (bottom of stat) until they will not turn any
further.
2. Release front housing by gripping lower half of outer frame and pulling
outwards then upwards
3. Place front housing somewhere safe
4. Run all wires to the wall box. Check to ensure that you have included the
following:
• Power (Live and Neutral)
• Heater (Live and Neutral)
• Floor sensor
• Fil pilote (if necessary)
• External/ 2nd oor Sensor (if necessary)
5. Pull wires through wall box and complete terminal wiring.
IMPORTANT: Ensure that multi stranded wires are fully inserted into the
terminals and secured tightly. Any loose strands should be trimmed as they
could cause a short-circuit.
If connecting more than two heaters, an electrical junction box will be required.
NOTE: Always ensure that the sensor cable is installed in a separate
conduit to the power cables supplying the thermostat and heating system.
Normal electrical installation (see numbering on diagram to right)
2. Connect to Power Supply (Live – 230V AC)
3. Connect to Power Supply (Neutral – 230V AC)
4. Connect to Warmup heater(s) (Neutral – MAX 3600W/ 16 Amps)
5. Connect to Warmup heater(s) (Live – MAX 3600W/ 16 Amps)
7. Connect to 1st wire of oor sensor (colour not important)
8. Connect to 2nd wire of oor sensor (colour not important)

Special installations:
(should only be performed under the supervision of Warmup)
Fil Pilote installation: (only for use in France)
Connect l pilot (F.P.) to terminal 1
Second sensor installation: (2nd oor probe or exterior probe)
You are able to attach a second sensor to terminals 6 and 7. You can then use external sensor function to dene the use of
that sensor:
Master/Relay installation: (connecting 2 stats together)
This feature allows you to use one thermostat to control another. This is useful if you need to control multiple underoor
heating elements with one program.
Use low voltage electric cable to connect terminal 6 on the “master” to terminal 6 on the “relay”
Use low voltage electric cable to connect terminal 7 on the “master” to terminal 7 on the “relay”
On the “master” thermostat these connector cables are in addition to the oor sensor but on the “relay” thermostat the oor
sensor is not necessary. The“relay”thermostat will no longer use its sensors for thermal regulation. It will now turn on/o in
tandem with the “master” thermostat.
- Installed in oor: This is to be used if the oor surface area is very large and delicate to overheating. The reading
from this secondary oor sensor will be used to monitor the overheat limit.
- Installed outside house: 2nd oor sesnor will engage weather compensation. Weather compensation saves energy
by delaying the start of heating period by 10 minutes if the dierence between internal and external temperature
is less than 5°C.

The 3iE has a Ingress Protection rating of IP20 but this rating can be increased when used in conjunction with the Gasket
(supplied separately), in which case it is ingress Protection rated to IP32 but only when used in accordance with these
instructions.
Fitting the Gasket
Remove backing from seal and attach to the back of the thermostat ensuring that there is a tight bond between the seal
and the back of the thermostat.
Once tted do not remove or attempt to ret the seal as this may aect the protection against ingress of water if the not
xed correctly.
Powering-up:
You can now power up the thermostat and begin the programming process. An easy to follow menu will guide you through
the rest. If you want to turn on / o the thermostat and heating system then hold down the recessed button on the bottom of
the stat for 3 seconds
When you have ensured that both the oor sensor and heating elements are working correctly you can complete the installa-
tion of oor covering and remove the protective cover on the front of the thermostat.
Error Messages:
Your thermostat can give you two error indications:
1. “er1”: This will occur if no oor sensor is detected
2. “er2”: This will occur if the oor sensor has a short circuit

Mounting thermostat into the wall box:
1. Push excess wire back through the wall box and insert thermostat back
module into wall box.
2. Put xing screws through mounting holes and tighten.
3. Ensure that thermostat is straight before tightening completely.
4. Replace thermostat front housing;
i) align and sit front housing on to hinges,
ii) push lower half of front housing until a ‘click’ is heard.
5. Ensure front housing is securely xed.
6. IMPORTANT: Tighten both retaining screws
