When the timer mode is on (unit indicator P 

 lit) the controller will

always display the symbol relevant to the current timer program; the
time shown is the current time of day.

When only one of the two programs has been selected, i.e. the start

that the Timer mode is off. To reactivate the timer mode, press
button C 

 twice.
