 Hassle free delivery of replacement product
 Value Selling
Danfoss Electric Heating Systems DEVIreg™ Touch Training | 30

31. Warranty and Claim Handling
 5 years product warranty
 Present market standard is 2-3 years but DEVI raise
the level to 5 years
 In some countries thermostats are considered as a
part of the building construction
 5 years warranty becomes a legal requirement
 End users tend to look at the whole system rather
than cables + thermostat
 expect a longer lifetime than e.g. a DVD player
Danfoss Electric Heating Systems DEVIreg™ Touch Training | 31

32. Warranty and Claim Handling
 5 years product warranty
 Present market standard is 2-3 years but DEVI raise
the level to 5 years
 Not all installers do neccesarily like the longer
lifetime due to the hassle related to this
 DEVI introduce hassle free delivery of
replacement product
Danfoss Electric Heating Systems DEVIreg™ Touch Training | 32

33. Warranty and Claim Handling
 Battery lifetime
 DEVIreg 550 problems
 A soldering process overheated and discharged the
batteries during production (problem solved)
 Tariff systems in part of Eastern Europe cuts of the
power to the thermostat 2x per day
 The battery is discharged faster
Danfoss Electric Heating Systems DEVIreg™ Touch Training | 33

34. Warranty and Claim Handling
 Battery lifetime
 Examples with power cuts discharging 1%
 Battery is 100% charged
 Life time, approx. 30.000 times
 Battery is 98% charged
 Life time, approx. 6000 times
 Battery fully discharged
 Life time, approx. 50 times
 Charging time on the last few percent is very long.

DEVIreg™ Touch Training | 34

35. Warranty and Claim Handling
 Battery lifetime
 Batteries shall when installing first time be charged the first day
without power cuts.
 Battery is afterwards able to withstand continuous
 power cuts of 1x a day of max. 14 hours continuously
discharging for about 10 years
 or 2x a day of 7 hours…..etc.
 As the cycle of power cuts in each market are very individual,
so it is best not to “promise somebody the moon”……but
instead send a request first.
 Otherwise the supply for the thermostat has to be separated
from the supply to heating elements via contactor in switchboard

36. Warranty and Claim Handling
 Hassle free delivery of replacement product
 Web based automated replacement system
 Installer can claim for a new thermostat directly
