Why is the output K 1/2 switched off in intervalls even if the commanded output signal is 100%?
If the "Electric Heat" output K 1/2 of the PCD7.L60x room controllers is written to 100% in RIO mode, it is still switched off after around 15 minutes for 2 minutes.
If the "Electric Heat" output K 1/2 of the PCD7.L60x room controllers is written to 100% in RIO mode, it is still switched off after around 15 minutes for 2 minutes. The firmware version (called SV on the label sticker) of the room controller is 1.08 and older.
This feature (switching off the output after 15 minutes for 2 minutes) has been implemented as "security mechanism" for the case that a battery is connected to the K 1/2 output.
As the experience has shown that this feature is not required, it has been removed in firmware version 1.11 and later.
In case the described behavior does negatively influence your installation, please replace the concerned controller by one with firmware version 1.11 or newer.
- Please note that for working with room controllers PCD7.L60x with firmware 1.11 the FBox library 2.1.007 (for PG5 1.4.300) is required.
- Room controllers PCD7.L60x with firmware version 1.11 are delivered starting in September 2009.
