0911 controller, so that the device will function perfectly and will have a long
service life.
• Keep to the standard engineering rules when planning and operating the
device!
• Installation and maintenance work may only be carried out by specialist
personnel using the correct tools!
• Observe the current regulations on accident prevention and the safety
regulations for electrical devices during the operation and maintenance of
the device!
• Comply with the intended usage of the device.

TWO OUTPUTS INDEPENDENT OF ONE ANOTHER (OUC = IND)
Example:
Default for the set-values SET1 = 50°C und SET2 = 20°C. With parameter
default OUC = ind, both set-values are completely independent of each other.
The control function must also be predefined. For the control circuit No. 1 Par.
S1C = in (heating, humidifying, etc.,) or S1C = dir (cooling, dehumidification,
etc.). Also predefined for the control relay No. 2 (S2C = in or S2C = dir).
Example: ouC = ind, S1c = dir, S2c = dir
TWO OUTPUTS INDEPENDENT OF ONE ANOTHER (OUC = DIP)
3-STAGE CONTROLLER
Example:
Default for set-value SET1 = 50°C (for control circuit No. 1). Then predefine a
number for SET2 = 5 Kelvin (Delta value). The resulting set-value is then SET2
= 55 °C (SET2 = SET1 + Delta-SET2). If SET1 is then increased, for example
by 2 Kelvin to 52°C, SET2 increases to the same extent, i.e., also by 2 Kelvin
to 57°C. Also define the control direction of the outputs via the parameters S1C
and S2C. In the same way, the set-value default limits for SET2 result from
LS2 = SET1 -Delta-LS2 and HS2 = +Delta-HS2.
8 - 0911
NEUTRAL ZONE CONTROLLER
Example:
Default for set-value SET1 = 50°C (for control circuit No. 1). In order to
configure a neutral zone control behaviour, always predefine:
SET2 = 0 Kelvin; LS2 = 0 and US2 = 0.
Configure the function of Relay 1 („uscita1“ in the following diagram):
S1C = in (heating) and Hy1= -2 Kelvin).
Configure the function of Relay 2 („uscita2“ in the following diagram):
S2C = dir (heating) and Hy2= +2 Kelvin).
Result (see following diagram):
SET1 = Set Point; db = Hy1 = Hy2
If the neutral zone SET1 - Hy1 is undershot, heating will take place (Relay 1
activated) until the set-value SET1 is reached. If the room temperature
exceeds the neutral zone SET1 + Hy1, Relay 2 is activated (cooling) and will
be switched off again at exactly SET1.

4.1General information regarding the installation and operation
ATTENTION!
NOTE
• Do not lay cables for inputs next to lines carrying voltage.
• Avoid heavy vibrations, aggressive gases, heavy soiling
and damp.
• Before connecting the device, check that the power supply
corresponds to the values shown on the rating plate.
• Observe the maximum loading of the relay contacts (see

The default parameters of the HOT-KEY will be automatically written into the
controller. During this time, the DoL message blinks in the display. The
programming prpcedure is finished after 10 sec, and normal operation
starts automatically with the new parameter set.
The HOT-KEY can be removed.
The following messages are possible at the end of the data transfer:
end for a correct data transfer
err for a failed data transfer
In this case, switch off the power to the device in order to repeat the
procedure. If you want to cancel the procedure, simply remove the HOTKEY.
UPLOAD (CONTROL DEVICE HOT-KEY)
Writing the current default parameters of the control device into the HOT-KEY:
Insert the HOT-KEY into the provided position when the controller is
switched on again.
Operate 1x with . The message uPL is displayed.
Press the SET1 button in order to start the data transfer. uPL starts to
blink.
You can remove the HOT-KEY again after about 10 seconds.
The following messages are possible at the end of the data transfer:
