Floor Probe Installation Instructions


The thermostats come with a 9’ sensor cable to detect the temperature under the floor finish. The end of the probe wire contains a capped sensor that should be evenly centered between two heating cables at least 12” into the heated area. At no time should the probe wire cross the heating cable.

Can I cut my floor heating mat if it’s too large?


Instead, try pulling the cable off the mesh and spacing the cable every 2 or 2.5 inches apart. Consult your installation manual with further questions regarding where the cable or mat can be run.

What are the electrical requirements for my Warmup system?


Please verify that the circuit can handle the amount of amperage your heating system requires. Your thermostat can only handle up to 15 amps so if you are connecting multiple heaters to one thermostat location, you may need to use a relay and a larger breaker. Your or your electrician can find out the amperage rating of your specific floor heating system in installation manual or printed on the box. Note: Just because the Warmup thermostats are dual voltage, this does not mean you can supply any voltage to your heating system. You must supply the voltage supplied to the voltage of your specific heater.

How to repair an electric floor heating cable system


Here is an instruction sheet that will guide you through the repair process of a damaged heating system wire.

How do I use my TDR Meter?


The TDR Meter is used to measure the distance to an existing fault in the wiring of your heating system. It sends an electrical pulse into the connected cable, traveling along the cable until it reaches the fault and then that pulse is sent back to the TDR. The time it took for that pulse to reach the fault and travel back is measured and converted to a distance reading that will appear on the TDR Meter.

Check the Resistance Readings of your Electric Floor Heating System


If you purchased a Digital Multi-meter from Warmup you will have 2 connectors as shown below. Please make sure that the contacts that will be plugged into the multi-meter are properly exposed as illustrated below. It is possible that you may have to remove some of the sheathing from the connector ends to expose them enough to make the needed contact with the multi-meter in order to receive accurate readings.

What does the ‘!’ mean on my 4iE Screen?


This may also mean that you have not yet registered the actual thermostat under your location as a room. Please make sure you have added a room, which requires you to enter the thermostats unique device number to fully register. 

If I’ve Registered an Account, Why Does my 4iE Still Have an ‘!’ on the Screen?


It could also mean that your thermostat is connected to the internet but you have not registered the device as a room on the myheating app or the my.warmup portal. In this instance, you will need to gather your 4iE’s device number and enter a room at your location on your profile. 

Connected to the internet and getting the 4iE ! message?


Ensure you have created your account and registered the thermostat using the Device Number. Click “Read More” for details. 

Why Won’t My 4iE Connect to the Internet?


Check you are using a WPA2 password format (less than 10 characters) on your network. Click “Read More” for details.
