-to be used in clean situation
INSTALLATION:
Thermostat:
The thermostat must be installed in a place away from vibrations, water and corrosive gas and where the
ambient temperature is within the range in the technical specifications.
For protection level IP65, the joint between the device and the surrounding of the panel space where it is
installed must be properly made.
Probe:
For correct readings, the probe must be installed in a place free of thermal
effects other than the temperature to be measured or controlled.
This diagram shows how the probe must be connected:
Connections:
Connect plugging terminals according to the rating plate diagram.
The probe and its corresponding cable should NEVER be installed in ducting along with mains, control
or power supply wiring, probe cables
