K-Series Dual Stage Dwyer Controller
The K Series 15, 20, and 30 ton chillers have a true dual stage configuration, with each of the two compressors having their own refrigerant circuit, and their own set point and differential. Attached please find the manual for this Dwyer 260 controller as well as the typical factory settings that the dual stage units ship with. Consult with KIG before making ANY changes. NEVER lower the parameter R4 or R5 below 42F without running a glycol solution at a concentration confirmed by KIG, or rupturing of evaporator can result. Password if required is “0” or “5”
