The limits IntMax and IntMin are only valid under external control (see
7.5.
Internal / external control) They restrict the temperature of the
internal bath to the desired maximum/minimum, also if the controller
would require a higher/lower temperature for the external system. As a
result the external setpoint may thus not be reached.
When operating the programmable controller under external control,
band limiting is active. The preset value determines the maximum
temperature difference between the internal bath and the external load.
This adjustment possibility prevents sensitive equipment and
temperature devices from damage.
The limitation „Crack protection“ shall avoid a partial overheating of the
still thick-flowing temperature liquid after switching on the circulator.
Heating and cooling power of the programmable controller are
adjustable.
100 % corresponds to the values in the technical specifications of the

Notice: - CoolingMax –
The assembled C.U.-cooling unit the menu point CoolingMax has to be set to a value >0
(Recommendation: 100%). So the automatic control of the cooling can become active.
Notice:
The parameters >IntMax< and >IntMin< are only supported from programme version V°4.xx
on. If the control electronics (V 4.xx) M1 is combined with an older version of the HT30
circulator, these parameters are not available. They will not be indicated in the menu.
