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.
