RF communication interval

According to A5-20-06

RF communication interval
Activation / installation

2 Minutes
(Will revert to A5-20-06 settings after 30 minutes)

Ambient Temperature
Activation / installation

Effective Ambient sensor value
(Will revert to approximated value after 30 minutes.  Calibration time in radiator closed situation 3 x 10 Minutes. Start value smoothing = 20°C); requires stable flow temperature when heating is on.
