2.2 Intended use
Programmable PID multichannel temperature controllers are intended for use in in-
dustrial systems. They are designed to control heating systems, condensing units,
alarms, fans, etc. Any other use of the device is permitted only with prior written
permission from the manufacturer.
They must not be used by private individuals, for example to control domestic hea-
ting or air-conditioning systems.
The temperature controller is intended only for incorporating into machinery, display
panels or switchboxes etc. and when fitted correspond to protection class 2 (double
or reinforced insulation). It may only be put into operation when installed. The use of
the controller is permitted in devices of protection class 1 and 2. The entire product
must not be changed or converted!
The temperature controller is ready for use only when the parameters have been set
appropriately. Its use before this has been done would have no benefits and could
also damage the equipment or adversely affect the medium to be temperature-con-
trolled.
The responsibility for the correct functioning of connected equipment lies with the
plant engineering company.
The controller is not suitable for use in explosive atmospheres. Danger of explosion.
Use only outside areas subject to explosive atmospheres.
The PID multichannel temperature controller fulfils the EC requirements for
electromagnetic compatibility (EMC) and the Low Voltage Directive (LVD).
The safety components meet the VDE regulations.
