Parameter description:
P1: Setpoint 2 / delta W
The second setpoint affects control circuit 2 and can be adjusted in 2 variants (see parameter A5
for selection):
First controller variant (cf. figure 1):
Contacts K1 and K2 are linked via switching
difference delta W (operation with delta W).
This difference may take on positive or
negative values. This allows you to
implement a leading or following secondary
contact.

Second controller variant (cf. figure 2):
Contacts K1 and K2 can be adjusted
independently. (Operation with setpoint 2.)
Contact K1 is based on setpoint 1, and K2 is
based on setpoint 2, which can be assigned a
limit function.

Note: When a PID control is implemented for contacts K1 + K2, setpoint 1 affects both contacts.
P2/P3: Hysteresis, K1/K2
The hysteresis may be symmetrical or one-sided relative to the setpoint (see A40, A41). When the
one-sided setting is chosen, the hysteresis works downward with the heating contact and upward
with the cooling contact. When the symmetrical hysteresis function is chosen, half of the hysteresis
value is effective above and half of the value below the switching point (cf. figures 3 and 4).
Figure 3: Heating controller, one-sided hysteresis Figure 4: Cooling controller, symm. hysteresis
P4/P5: Upper/lower control range limit
The adjustment range of the setpoint can be limited in both directions. The purpose of this is to
prevent the operator of a unit from setting impermissible or dangerous setpoints.
P6: Actual value correction
A correction can be applied to the actual value. This correction value is added to the actual value
across the entire measuring range.
P7: Proportional band
In the proportional band, the output is controlled in proportion to the deviation from the setpoint.
The greater the system deviation, the greater the control output.

P8: Reset time Tn, I-portion
The proportional controller as such has a remaining deviation of the actual value from the setpoint.
The integral portion provides for a complete compensation of this offset.
The reset time is a measure for the period of time needed to adjust a remaining temperature
deviation of the size of the proportional range.
If a small reset time is set, a fast post-adjustment will take place. At a too small reset time,
however, the system may tend to vibrate
P9: Derivative time Tv, D-portion
The differential portion dampens temperature changes. If a long derivative time Tv is set, damping
is strong. At too long derivativetime, however, the system may tend to vibrate. At setting 0 the
values are ineffective. It is therefore possible to realizea pure PI or PD regulation.
P10: Cycle time Tp
The cycle time is the time during which the control output cycles through a switching period, that is
from On through Off. The lower the cycle time setting, the faster the control. However, this also
results in increased output switching frequency, which may quickly wear out relay contacts.
In the case of veryfast processes with high switching frequencies, a voltage output is therefore
preferable.
P19: Keypad locking
The keypad locking function can be used to block the control keys. When keypad locking is
enabled, the setpoint cannot be changed. Any attempt to change parameters with keypad locking
enabled will display the message “===”.
P30: Lower alarm limit
P31: Upper alarm limit
A limit or range alarm with a fixed hysteresis of 1.0 K is signaled using lamp 3 or contact K3.
Function as a limit alarm (cf. figure 5):
If the actual value is outside the defined
temperature limits (that is, above the upper
limit or below the lower limit), the alarm
contact is active.
Figure 5
Function as a range alarm (cf. figure 6):
Inverted switching behavior compared to limit
alarm. Lamp 3 is lit or contact K3 is picked up
when the actual value lies within the defined
limits.
Figure 6
The limit values for the limit or the range alarm can be set to be relative, i.e. to float with the
setpoint, or to be absolute, i.e. to be independently adjustable. If only one switching point is desired
for the limit alarm, the second switching point (the one not needed) is set to a value above or below
the controller working range. It is then preferable to choose the operating mode with absolute
limits. Also see A30 within this context.

P32: Hysteresis, alarm contact
The hysteresis is to one side of the limit. In the case of the limit alarm, the hysteresis works upward
from the lower limit and downward from the upper limit. In the case of the range alarm, the
hystereses work in the opposite directions, i.e. downward from the lower limit and upward from the
upper limit.
P33: Lower limit for fan
P34: Upper limit for fan
P35: Start-up boost time
Third control level (A parameters):
Setting of control parameters
The third control level is reached by first accessing the second control level and then scrolling
through the parameter list all the way to the highest parameter (P45). Then press the UP key for a
minimum of 10 seconds. The message “PA“ appears on the display.
Press the UP and DOWN keys at the same time for a minimum of 4 seconds to access the
parameter list of the third control level (which starts with A1).
Press the UP key to scroll up in the list and the DOWN key to scroll down in the list.
Press the SET key to display the value of the parameter in question. To adjust the value,
additionally press the UP key or DOWN key.
Once you release all keys, the new value is permanently stored. If no key is pressed for more than
60 seconds, the unit automatically returns to its initial state.

Parameter description:
The following values may change the equipment
characteristics and are therefore to be set with the utmost care:
A1: Fan controller mode
A2: Control circuit 2 mode
The controller mode (cooling or heating function) can be individually programmed for the two
control circuits at the factory. Heating function means that the contact drops out when the defined
setpoint is reached, i.e. the power supply is interrupted. In the case of the cooling function, the
contact only picks up when the actual value is above the defined setpoint.
A3: Fan controller function in the event of a sensor error
A4: Control circuit 2 function in the event of a sensor error
When the sensor is broken, the flashing display indicates F1H. When the sensor is short-circuited,
the display indicates F1L (also flashing). Parameter A3 is used to determine the output behavior
when this happens
A5: Selection of setpoint 2 / delta W for control circuit 2
This parameter determines whether the controller works with two linked contacts (operation with
delta W) or with two independently adjustable contacts (operation with setpoint 2). See P1.
A8: Display mode
This parameter selects the resolution used to display the actual value.
A19: Parameter lock
This parameter can be used to lock (block accessto) the parameter levels. When the A level is
locked, only parameter A19 can still be changed.
When the parameter lock is active, the parameters are displayed but cannot be changed via the
keys. Any attempt to change parameters with keypad locking enabled will display the message
“---“.
A30: Alarm contact function
This parameter is used to determine alarm contact behavior when the values set with parameters
P30 and P31 are reached.
Limit alarm means that an alarm is signaled when the defined limits are exceeded.
Range alarm means that an alarm is signaled within the defined limits.
Relative means that the values entered for parameters P30 and P31 represent a difference from
the setpoint. Absolute means that the values entered for parameters P30 and P31 are independent
of the setpoint.
A31: Special limit alarm function
This parameter can be used to activate additional actions for the limit alarm function.
A32: Default display setting
When parameter A32 is set to 1, the display always indicates the setpoint. It is then not possible to
display the actual value.
A40 Hysteresis mode of fan controller
A41 Hysteresis mode of control circuit 2
These parameters determine whether the hysteresis values adjusted with P2 or P3 for the fan
controller or control circuit 2 are symmetrical or one-sided relative to the switching point in
question. When the symmetrical hysteresis function is chosen, half of the hysteresis value is
effective above and half of the value below the switching point. When the one-sided setting is
chosen, the hysteresis works downward with the heating contact and upward with the cooling
contact.

A52: Minimum action time for control circuit 2 “On”
A53: Minimum action time for control circuit 2 “Off”
These parameters can be used to delay activation/deactivation of the output contact in order to
reduce the frequency of switching operations. The minimum action time defines the entire
minimum duration of a switch-on or switch-off phase. This time is also effective for the
configuration as an alarm contact.
A54: Control circuit delay after “power on”
This parameter can be used to delay the activation of the control circuit after power on. The
purpose of this is to prevent mains supply overload due to many consumers being switched on
simultaneously.
A56: Suppression of limit alarm after “power on”
When the controller is switched on, it takes a certain period of time –particularly with cooling
systems –until the operating temperature is reached. This would normally result in undesirable
alarm signaling.
Therefore parameter A56 can be used to define a period of time during which an alarm condition is
not signaled.
A57: Continuous fan operation
A60: Sensor selection
Selection of sensor. Depending on the hardware used, not all sensor types can be selected.
A70: Software filter
Calculates the mean value over the number of measurements set here.
A 80: Temperature scale
This parameter is used to switch the display between the Fahrenheit and Celsius temperature
scales. It is not available on units with a voltage or current input.
A90: K1 output linking
