Parameter description
WARNING!
The following values can change the instrument
characteristics and must therefore be made with great care.
A1: Switching mode, control contact
The switching mode for the controller can be set as Heating or Cooling
function. With a heating controller, the respective contact is closed when
the actual temperature is lower than the set temperature. For a cooling
controller it is the inverse.
With A1 = 2, Relay K1 is assigned the function "alarm" and then has two
switch points.
A3: Function of the control contact on sensor error
With a sensor error the controller contact adopts the state set here. If
an error is detected in the parameter memory (display EP), and thus
the stored settings cannot be utilised, all relays are placed into the
de-energised state.
A8: Display mode
The actual value can be displayed as an integer or with a decimal point
to a resolution of 0.1 °C. All parameter settings and set points are mainly
displayed with a resolution of 0.1 °C.
A19: Parameter lock
This parameter enables a stepwise blocking of the individual parameter
levels. On locking the A level, only the parameter A19 itself can be
altered.
In the locked state, the parameters are displayed, however, changing
them via the keys is not possible. If, despite the lock, one tries to alter the
parameter, the message "---" will be shown in the display.
