Connecting the Dry Contact
(LG Manufactured; Model Nos. PDRYCB100 and PDRYCB300; Optional; Sold Separately)
The Dry Contact unit is designed to enable or disable normal Hydro Kit operations, or determine occupancy for setback temperature setting
through a binary input. A binary output indicates if a system malfunction occurred. A field-supplied binary signal could be triggered using a
timer, keycard switch, door switch, motion detector, or an occupancy sensor.
To install a Dry Contact, see the Dry Contact submittals and / or installation manuals on www.lghvac.com, or contact your LG representative.
• Connect the Dry Contact to Terminal CN-CC on the Hydro Kit PCB.
• See the Pre-Commissioning section for function codes and instructions on accessing Installer mode that will be needed to set up Hydro Kit
accessories.
