7 Thermo-controller Operation
Do not plug, mount, unplug or touch the connectors during operation!
You may otherwise provoke destruction or malfunction. Turn off all power
sources before working on the modules. This also applies to any peripherals
connected such as encoders, programming devices with external power
source, etc.
7.1 Starting up
Before supplying power, again check that all connectors are properly wired
and that the polarity is not reversed.
Switching on
The thermo-controller has no power switch of its own.
The unit is turned on either together with the system or by connecting a
power supply.
Switching off
To turn off the thermo-controller either turn off the system or disconnect the
unit from its own power supply.
