Check that the polarity of 1-wire bus to the RH sensor is correct.  AAG
seems to have a different idea of the RJ 11 connector wiring from that
used on TAPR devices.  (also to make it more interesting, some 
telephone cables are straight through and some have a 'twist')

I press menu till HUMIDITY SENSOR shows up, then SELECT and then DOWN (to say I just want the RH reading from that sensor and not the temperature). Then I press menu again to get out of the setup. "Display current data" shows up. But when I press select, it says no ID's have been programmed, to run setup.
