unistat control V3.8.1
Appendix A - Program Directory
The setting of operating modes or unit parameters is carried out using programs. These are
stored in an extensive memory in the control panel. Some programs only switch from one
operating mode to an alternative (for example ‘control mode’ program 3), with others
parameters have to be entered (for example ‘set point’ program 0) and some need a proper
dialogue (for example ‘setting heating program’ program 20).
The program selection is initiated by pressing , after that the program number must be
entered, then press . A short description of the program appears on the LCD display
unit together with a display of the current setting.
Entering the numerical values for the parameters, for example the set point, is done via the
number keys … , sometimes also by using the decimal point and the minus
sign . The programming is confirmed by pressing .
Corrections are possible by pressing . A programming mistake is stopped by pressing
. Should a mistake be confirmed with , it can still be rectified by calling up the
program and entering the new parameter.
! Not every control panel is equipped with all programs! This depends on the software
status!
The software of the unistat control monitors logic discrepancies. A change of the minimum –
maximum set point, for example, during activated circulation is not possible. If you try such
change you will be warned (display ‘ Not allowed!’). The programmed change is rejected.
Program 0: Setting set point
After selection, ‘enter set point’ appears on LCD display. The set point is entered with
to , and keys. The actual programming is done by pressing . The
value of the set point is depending on the currently set minimum set point and maximum set
point. The rule is:
Minimal set point < = set point < = maximum set point.
If this rule is not obeyed, an error message appears and the setting is ignored. The step size
for the entry is 0.1K. You can choose to enter the second digit after the comma, by not
pressing at the end, but by just entering another digit. With this you can reach a
setting resolution of 0.01K.
entering set point of 20.5 °C,
(without !) setting a set
point of 20.55°C.
The activation of this program is achieved by pressing , this is the
same as pressing the Hotkey .
Program 1: Setting Of Minimum Set Point
After selection, the program name appears and the current minimum set point appears.
The value is entered by pressing keys … and . Only whole numbers are
possible, no digits after comma. The entering is done by pressing . The value of the
minimum set point is depending on the current set point and the unit parameters
(Lowest permissible temperature). The rule is:
Lowest permissible temperature < = minimum set point < = set point.
If this rule is broken, an error message appears, and the setting is ignored.
