4. Pre-commissioning checks
These temperature control systems have been designed and manufactured to the highest
industrial standards. In order that they function correctly, please observe the following points
and then proceed with the 'Display adjustment' in Section 5 for adjusting to the desired set
temperature.
Factory temperature setting
In order to avoid accidental damage due to exposure of extreme temperatures, the unit is
factory adjusted to its highest set temperature. This value will vary according to the data
shown in Table 2.
Overtemperature protection
In the event that the overtemperature protection is exceeded by the values shown, serious
damage will occur and the warranty will be invalidated. Before commissioning this unit, please
ensure that the system temperature cannot exceed the overtemperature protection value.
