Comfort 2 Ultra and KP01 Keypad

[AndreSz]

I am upgrading my old Comfort 1 system to Comfort 2 Ultra, but I am having problems with my existing KP01 keypad - Audio from the Keypad is distorted.

The comfort 1 had a pot to adjust the audio level, but the Comfort 2 does not.
- So is the KP01 basically not compatible ? - do I need a KP03 ?

Best to fit a new keypad
If you are brave and have time to spare then you might like to adjust various parameters listed under Comfiguraton settings - tuning parameters
There is an explanation in the engineer set up guide.....

KP01a dn KP03 are obsolete.

The new models are KP04A, KP05A, KP06A.

In a related question is the \"Comfort Ultra II Slave Expansion Panel Plug-in Flash Upgrade [MPU01-SEM]\" compatible with the SEM02 slave expansion panel.

The 4.95 firmware on my slave expansion panel is not talking to the comfort II ultra or the UCM/ETH03, So I assume it needs the Flash upgrade.

The firmware 4.95 in the Slave is not firmware flashable. It cannot be upgraded. You will have to replace it

So can I use a
\"Comfort Ultra II Slave Expansion Panel Plug-in Flash Upgrade [MPU01-SEM]\"
to upgrade the firmware on a SEM02 slave expansion board.

The slave 4.95 does not have a plug-in flash upgrade
Slave with firmware 5.XXX have sockets for plug in FlashThe only option is to replace with a new one. That model is about 20 years old
