Please read this operating manual before starting up carefully.
Observe the installation and connecting instructions.
Before operation, the unit must be configurated for its intended purpose under an expert guidance.
(e.g. controller type, sensor type and range, alarm adjustment etc.)
See: „Configuration Level“ and „Parameter Level“
Attention: The „heating“- or „cooling“-outputs can be active while programming or configuring the controller.
This can cause a damage either to the plant itself or its contents.
Disclaimer of liability
We have checked the contents of the document for conformity with the hardware and software described. Nevertheless, we are unable
to preclude the possibility of deviations so that we are unable to assume warranty for full compliance. The information given in the
publication is, however, reviewed regularly. Necessary amendments are incorporated in the following editions.
We would be pleased to receive any improvement proposals which you may have.
The information contained herein is subject to change without notice.

IV. Installation Instructions
Make certain that the devices described here are used only for the intended purpose.
They are intended for installation in control panels. The controller must be installed so that it is
protected against impermissible humidity and severe contamination.
In addition, make sure that the permitted ambient temperature is not exceeded.
The electrical connections must be made according to the relevant locally applicable regulations.
If using a thermocouple sensor, the compensation cables must be laid directly to the controller
terminals.
Transducers must be connected only in compliance with the programmed range.
Transducer cables and signal lines (e.g. logic or linear voltage outputs) must be laid physically
separated from control lines and mains voltage supply cables (power cables) and must be shielded.
Spatial separation between controller and inductive loads is recommneded.
Interference from contactor coils must be suppressed by connecting adapted RC-combinations
parallel to the coils. Control circuits (e.g. for contactors) should not be connected to the mains power
supply terminals of the controller.
IMPORTANT:
Before operation, the unit must be configurated for its intended purpose
(e.g. controller type, sensor type and range, alarm adjustment etc.).
Please see „Configuration Level“.

Process- and Setpoint value will be displayed simultaneously.
Within the operating level the setpoint and the alarm value can be adjusted
by pressing the " " / " " - keys.
Every adjustment has to be quit by pressing the „ E “ - key.
All parameters within the operating level can , in succession, be displayed by pressing the „ P “ - key
and adjusted by pressing the " " / " " - keys.
Parameter level
Within the parameter level the values are adjusted to suit each individual process.
This level is reached by simultaneously pressing the "P" - and " E " -keys.
Configuration level
In the configuration level the controller type, input type, sensor range and the alarm behaviour
can be pre-selected.
This primary information has to be entered before taking the controller into operation.
The configuration level is reached by simultaneously pressing the "P" - and " E " - keys
for a period of approx. 5 seconds.
The display of each single parameter within the parameter and configuration levels, and their adjustment,
are made in the same fashion as within the operating level.
After either pressing the „E“ - key for approx. 1 second, or waiting for a period of approx. 30 seconds,
the unit will automatically return to the operating level (display of process value and setpoint).

The output ratio shows the momentary calculated ratio.
It cannot be altered. The display is in percent of the installed
performance capability for heating or cooling.
Output ratio for cooling is shown as a negative value.
1LY OUT 1- output ratio limit 0...100 % (ex works: 100)
2LY OUT 2- output ratio limit 0...100 % (ex works: 100)
Only adjustable, if a heating-off-cooling mode is programmed.
A limitation of the output ratio is only necessary when:
- the heating or cooling energy supply is grossly over dimensioned compared to the power required, or
- to turn off a control output (setting = 0%).
Under normal circumstances no limitation is needed (setting = 0%).
The limitation becomes effective, when the controllers’ calculated
output ratio is greater than the maximum permissible (limited) ratio.
Warning!
The output ratio limitation does not work during autotune.

Normally the controller works using PD/I control action.
This means, controlling without deviation and with practically
no overshoot during start-up.
The control action can be altered in its structure by making the
following adjustments to the parameters:
a. no control action, on-off (setting P = OFF)
b. P-action (setting D and I = 0)
c. PD-action (setting I = 0)
d. PI-action (setting D = 0)
e. PD/I modified PID-action
1CY OUT 1- cycle time 0,5...99,9 secs (ex works: 15,0)
The switching frequency of the actuator can be determined
by adjusting the cycle time. This is the total time needed for the
controller to switch on and off once.
a) Relay outputs: cycle time > 10 secs
b) Bistable voltage outputs: cycle time 0,5...10 secs

This parameter raises the setpoint (switch-point) for cooling output
by the displayed value. It can be help to reduce the switching
frequency between the heating and cooling outputs, if this is to
high.
Simultaneously activation of heat and cool outputs is not possible.

OPt self tuning OFF self tuning out of action
(autotune) on self tuning on request ( one time)
Auto self tuning automatically if the controller is switched on
and if the difference between process value and
setpoint is > 7 % of the range.
The tuning algorithm determines the characteristic values within the controlled process, and calculates
the valid feedback parameters ( P,D,I ) and the cycle time ( C = 0.3 x D ) of a PD/I-controller for a
wide section of the range.
The determined parameters for heating are also adopted for cooling.
The self tuning activates during start-up shortly before the setpoint is reached. The setpoint must
amount to the least 5% of the total range.
If activated after the setpoint has already been reached, the temperature will first drop by approx. 5%
of the total range, in order to detect the exact amplification of the process.
The tuning algorithm can be activated at any time by selecting the OPT=on and pressing the „E“-key.
During self tuning „Opt“ is shown in the display, alternating with the setpoint value.
Using the heat-cool controller, the temperature drop will be accelerated by switching on the cooling
for a short duration.
After having calculated the correct feedback parameters, the controller will lead the process value
to the setpoint.

OFS process value offset -199 ... OFF ...+199 °C/°F (ex works: OFF)
-19,9 ... OFF ... +19,9 °C/°F
This parameter serves to correct the input signal, e.g. for:
- the correction of a gradient between the measuring point and the sensor tip,
- the line resistance balancing of 2-line RTD (Pt100) sensors and
- correction of the control devition when using P- or PD-action.
If for example the offset value is set to +5°C, then the real temperature measured by the
sensor (when process is balanced) is 5°C less than the setpoint and the displayed process value.
