Control for low cond.
temperature
152 Output signal (0-10 V) to control the condenser water
inlet valve
Simple installation: for applications with cold water
at condenser inlet (ex. ground-source, groundwater-
source, superficial water-source applications) the
signal permits to control a 2 or 3-way valve to
maintain condenser water temperature (and so
condensing pressure) at acceptable values
