Venstar VSACC0410 Relay R-22 This piston-style actuator features aThe Venstar VSACC0410 Add A Wire Relay is a critical solution for retrofitting thermostats in applications where additional conductors are unavailable. Functioning as a 4 to 5 wire adapter, this relay allows a 4 wire cable to operate like 5 wires, specifically providing a common wire (C wire) path without the labor intensive process of pulling new thermostat wire through finished walls or tight plenums. As the direct replacement for the P474 0410, the
