Safety instructions
1 Safety instructions
For your own safety, follow these instructions concerning the mounting, start up and operation of the controller:
− The controller is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product.
− For electrical installation, you are required to observe the relevant electrotechnical regu-
lations of the country of use as well as the regulations of the local power suppliers. Make
sure all electrical connections are installed by trained and experienced personnel. Before
performing any such work on the controller, disconnect it from the power supply.
− The controller is designed for use in low voltage installations. For wiring and mainte-
nance, you are required to observe the relevant regulations concerning device safety and
electromagnetic compatibility.
To avoid damage to any equipment, the following also applies:
− Proper shipping and storage are assumed.
− Before start-up, wait until the controller has reached the ambient temperature.
1.1 Disposal
Waste electrical and electronic equipment may still contain valuable substances. They may
also, however, contain harmful substances which were necessary for them to function. For
this reason, do not dispose this kind of equipment together with your other household waste.
Instead, dispose of your waste equipment by handing it over to a designated collection point
for the recycling of waste electrical and electronic equipment.

3.4 Calibrating sensors
The controller is designed for connection of Pt1000 sensors. The Pt 1000 resistance values
are listed on page150.
If the temperature values displayed at the controller differ from the actual temperatures, the
measured values of all connected sensors can be recalibrated. To calibrate a sensor, the currently displayed sensor value must be changed such that it matches the temperature (reference temperature) measured directly at the point of measurement. Sensor calibration is activated in CO5 in F20 function block.
An incorrect sensor calibration can be deleted by setting F20 - 0.
Turn the rotary switch to (settings).
