smart Econ Temperature sensor
Universal sensor elements are available for measuring temperatures.
“smart Econ Temperature sensor” on page 145
These can:
• be plugged into preconfigured thermowells [universal sensors] (supply temperature, boiler tem-
perature, etc.)
• be attached to pipelines [pipe-mounted sensor] (storage tank temperature, flow temperature, etc.)
• be used as smart Econ outside temperature sensor in a weather-resistant housing
If required, you can alternatively use other temperature sensor versions (outside sensor, air duct
sensor, wall mounting room sensor, flush mounting room sensor).
The temperature sensors are protected against reverse polarity.If a temperature sensor was con-
nected incorrectly, this will be automatically detected and signaled during startup.Interruptions in the
circuit are also detected and signaled.
Note:
If the display shows "polarity reversal", this may also be due to a short circuit in the signal
lines.
Temperature sensor polarity
Terminal
red
even terminal number (e.g. 10)
white
uneven terminal number (e.g. 11)
NOTE
Only connect temperature sensors and contacts.
Never apply voltage!
