The 3iE thermostat is designed to aid in the comfort of your home by providing timed regulation of your Warmup floor heating system. The thermostat is designed to receive temperature input signals from the following sensors:
- Air sensor located inside the thermostat
- Floor sensor installed in the floor to be heated (see Warmup heating product instructions for details)
- Optional 2nd sensor (either installed on the floor or outside the house)
The thermostat is not a safety device and should only be used with Warmup heating products. In order to avoid damaging your flooring the correct floor type should be selected during the thermostat programming process.

WET AREAS
Install the thermostat a minimum of 5ft away from showers, tubs and other
sources of splashing water.
INSTALLATION
To install your thermostat on the wall, you’ll need a 4″x4″x2-1/8″ square back box with a single gang mud ring (also called plaster ring).
Opening the thermostat
- Separate the front housing of thermostat as shown on the picture
- Unscrew both closing screws (at the bottom) until they don’t turn any further.
- Release front housing by gripping lower half of outer frame and pulling outwards then upwards. Place front housing somewhere safe.
Placing the back box
- Open the back box and create openings by pushing one or two holes.
- place the rear part into the wall where you’ve chosen to place the thermostat.
- With 2 screws, secure the back of the 3iE to the face of the electrical box (see picture on opposite page).
Connecting wires
- Attach the sensor wires into the thermostat following the instructions on page 8.
- Check to ensure that you have all the following wires connected to the back panel of the thermostat:
- Power lead (Line 1 and Line 2 )
- Heater wire (Line 1 and Line 2)
- Floor sensor
- External/ 2nd floor Sensor (if necessary)
- Complete wiring as explained on the following pages.
- Pull wires into the electrical box.
IMPORTANT
Ensure that multi-strand wires are fully inserted into twist-on wire
connectors (wire nuts) and secured tightly. Any loose strands should be
trimmed as they could cause a short circuit.
**Mounting the thermostat
**
- Close the electrical back box by screwing the front part (already attached to the back module of the thermostat) onto the rear part installed into the wall.
- Ensure that the thermostat is straight before tightening completely.
- Replace the thermostat’s front housing;
- align and sit front housing on to hinges,
- and push lower half of front housing until you hear a ‘click’.
- ensure front housing is securely fixed and insert the retaining screws.
- Tighten both retaining screws.
Note: Do not obstruct the thermostat’s vents.
ELECTRICAL WIRING
Connect the power base wires to the power supply and load using twist-on wire connectors for copper wires (see diagram below), as supplied in the packaging box.
- Connect the power line to the thermostat line cables marked L1 and L2.
- Connect the heating cable to the thermostat load cables marked Load 1 and Load 2. (max 15 amps)
- Connect to 1st wire of floor sensor to terminal 1 (color not important)
- Connect to 2nd wire of the floor sensor to terminal 2 (color not important)
NOTE: All cables and connections must be carried out by a qualified electrician and must conform to the local electrical code.
POWERING UP & ERROR MESSAGES
Specific wiring
Second sensor installation (2nd-floor probe or exterior probe)
- Connect to 1st wire of external sensor (2nd-floor sensor) to terminal 2
- Connect to 2nd wire of the external sensor (2nd-floor sensor) to terminal 3
Master/Relay installation (connecting 2 stats together)
- Connect from terminal 3 on the “master” to terminal 3 on the “relay” thermostat.
- Connect from terminal 2 on the “master” to terminal 2 on the “relay” thermostat.
NOTE: The “relay “ thermostat will no longer use its own floor sensor for thermal regulation. It will turn/off in tandem with the master thermostat.
Powering up
You can now power up the thermostat and begin the programming process. An
easy-to-follow menu will guide you through the programming. If you want to
turn on / off the thermostat and heating system, hold down the recessed button
on the bottom of the stat for 3 seconds. It is important to test the GFCI for
correct installation and function. Testing can only be carried out while the
thermostat is calling for heat (see operating instructions for details). When
you have ensured that both the floor sensor, heating elements, and the GFCI
are working correctly you can complete the installation of floor covering and
remove the protective cover on the front of the thermostat.
