Belimo Zip Economizer Temperature and Humidity Sensor, Outside Air
ECON-ZIP-TH Sensor may be used to measure temperature and humidity in the
outdoor air or return air location. The temperature and humidity output is via 2 discrete
channels that can be independently measured with a multimeter. One sensor is used
in the outdoor air intake for single enthalpy changeover strategy. An additional sensor
can be added in the return air stream for differential changeover strategy. When using
the ECON_ZIP_TH it is not necessary to use a separate temperature sensor ECON-ZIP-
10K for OAT or RAT.
