DCC-2 Dual System Control Adapter

TrolMaster DCC-2 is a dual system control adapter that lets two TrolMaster controllers (e.g., Hydro-X and Carbon-X) share one plug-in device station, so a single device can run under two conditions. It connects via a built-in RJ12 lead and works with DSC‑1, DSH‑1/2, DST‑1/2, DSP‑1, DSD‑1 and DSV‑1 modules. Typical use: allow the same exhaust fan assigned to climate control to also run for CO2 emergency exhaust. An interlock function determines whether both conditions must be met or either one can activate the device. Rated 12 VAC, 0.2 A, and suitable for 32–122°F up to 90% RH. Package includes 1 DCC‑2. Ideal for sharing fans, dehumidifiers, humidifiers or CO2 equipment between systems without duplicating hardware.
