 constant temperature setting, and the electrical heater does not start,
then enter constant temperature control
The temperature and its frequency during constant temperature program. Recorded by
the above chart
ƸT=T1-Ts+2ć, ƸT has 10 areas, from 0 to 9, the rule of constant
a)
when ƸT is changing
i) When ƸT is increasing, the frequency increase 1 to run
ii) When ƸT is decreasing, the frequency decrease 1 to run
b) when ƸT stay at a area as 3 minutes, the rules as follow:
4 ̚ 8: the present frequency increase 1( keep 10 min to increase 1) ˈuntil get the
maximum frequency.
3: frequency is unchanged
0̚2: The present frequency decrease 1 to run, until the frequency is get to F1
temperature program’s frequency is
