Visual checks

VISUAL CHECK ONE

Cracked LCD display

This fault is caused when someone

attempts to remove the front cover of

the thermostat. This is normally

removed by carefully pushing down

on the plastic tab in the top central

grill. If care is not taken, the

implement used to push down the

tab slips and damages the display,

causing it to crack. This damage can

also be caused by over-tightening of

the screws.

This fault is caused when the

electrics entering the back of the

thermostat are stripped back too far,

exposing the live conductors. When

this happens, if these exposed wires

cross, they short and cause the fuse

to blow and the back of the

controller to be blackened.

Remove the front cover and inspect

the back of the LCD display. At the

back are a set of gold connector

pins, these leave the factory

straight, if they are bent or

distorted then a heavy hand has

been used to plug the display into

the base of the thermostat.

VISUAL CHECK TWO

Blackening at the rear of the

thermostat

VISUAL CHECK THREE

Bent pins

These instructions will help to identify whether the fault with your underfloor heating system has been

caused due to mis-installation/not following user instructions.

If these VISUAL checks are carried out correctly, the thermostat may not have to be returned to DEVI,

which will save you time.

In all three examples, the thermostat would not be covered by the DEVI Warranty.

In this case a new thermostat should be purchased.
