Heating and cooling with constant period (

CyCl=3 )

The adjusted cycle times

t1 and t2

are met in the overall output range . To
prevent unreasonably short pulses,
parameter tp is used for adjusting the
shortest pulse duration. With small
correcting values which require a pulse
shorter than the value adjusted in

tp,

this pulse is suppressed. However, the
controller stores the pulse and totalizes
further pulses, until a pulse of duration
tp can be output.


Parameters to be adjusted

t1 :

Min. cycle time 1 (heating) [s]

(

PArA/ Cntr)

t2 :

min. cycle time 2 (cooling) [s]

tp:

min. pulse length [s]
