When the machine is installed in particularly cold climates, the operation of the controller or LCD display may be
impaired. To ensure that this does not happen, a heating resistor housed inside the electrical cabinet is controlled
through a digital output DO1.
The heater is activated when the indoor temperature of the electrical panel falls below the PE31 activation threshold
and is deactivated when it rises above this temperature + PE32 return differential. Activation of the resistor can be
disabled by parameter PE30.
Attention: if the user disables this function, said user is responsible for any failures or breaks caused by the low
temperature.
