What is the firmware version of the Comfort 2?

The latest Comfort 2 firmware has some improvements in the transmission of IR codes

It may be a range issue if the ir code works in some rooms at diferent distanbces
Can you temporailyt short out the 100 ohms reistor so that the IR led fully driver. Just to ensure that the codes are sent correctly. The 100 ohms resistor is meant to protect the output in case the putput is permanently turned on

Power versus range was my initial thought - hence my Q about the Comfort 2 output voltage (versus Comfort 1) or the OP1 board is faulty.

I\'m sure the IRM01 was originally sold with an 8m range.

Couldn\'t bring myself to short it out completely. Dropped the value to 40ohm and it works OK now.

100ohm seems a low value for an LED. What is the Vf & I for this LED? Perhaps I can leave it at 40ohm?

In fact remote control internal resistor may be around 10 ohms or less. This is because there is no possibllity of latching the output on permanently, whereas Comfort Outputs  can be controlled by the user and there is nothing to stop its output being turned on  by an action.

Leaving at 40 ohms should be OK

The new IRIO with ISM03 Infrared submodule sends the IR codes using a Set Flag or counter command, and direct control of the Output to ON state is not allowed. That is the preferred method for new installlations

I\'ll leave the 47ohm in place and leave it on test for a while.
