Two-condition logic for any Hydro-X plug-in module — parallel or series interlock.
The TrolMaster DCC-1 Dual Condition Adapter adds multi-condition trigger logic to your existing Hydro-X setup, letting a single device station respond to two independent environmental inputs — either independently (parallel) or only when both are met simultaneously (series).
Every plug-in device station in the TrolMaster Hydro-X system is designed to respond to a single control condition by default — temperature, humidity, CO2, a timer, or a setpoint. The DCC-1 Dual Condition Adapter changes that. It bridges two separate plug-in modules together so that one physical device can be governed by two conditions at once, without rewiring or adding a separate controller.
The adapter connects to a compatible plug-in module via its built-in RJ12 cable and then coordinates the logic between that module and a second one. The result is a single device — an exhaust fan, a CO2 solenoid, a chiller relay — that responds to the combined or individual states of both modules simultaneously. This is condition-stacking inside the existing Hydro-X architecture, not an add-on workaround.
The DCC-1's core feature is its Interlock switch, which selects between two fundamentally different trigger behaviors. Understanding which mode fits your use case is the starting point for configuring the adapter correctly.
Interlock OFF places the two modules in a parallel relationship: either condition alone is sufficient to activate the connected device. A common example is triggering exhaust fans when temperature exceeds the setpoint OR when relative humidity exceeds its setpoint — whichever trips first starts the fan. A second example: run exhaust during a recycling timer window OR whenever CO2 climbs above target. Any single condition firing is enough.
Interlock ON places the modules in a series relationship: both conditions must be satisfied simultaneously before the device activates. This is useful for safety-style interlocks — for instance, disabling a CO2 enrichment device only when exhaust fans are actively running, or cutting lighting power only if temperature AND a secondary condition are both outside acceptable ranges at the same time. Requiring two simultaneous triggers prevents nuisance shutdowns from a single transient event.
The DCC-1 is designed to pair with TrolMaster's plug-in style device stations: DSC-1 (CO2 device station), DSH-1 and DSH-2 (humidity device stations — 120V and 240V), DST-1 and DST-2 (temperature device stations — 120V and 240V), DSP-1 and DSP-2 (day/night setpoint modules), DSV-1, and DSD-1. The built-in RJ12 cable connects directly to the module's bus port with no additional cable required for the primary connection.
The DCC-1 is backward compatible across the Hydro-X platform, including the original HCS-1 and the HCS-2 Pro. It does not require any firmware update to the main controller — the logic is handled at the adapter level between the two modules. For operations already running TrolMaster infrastructure, the DCC-1 slots into the existing RJ12 bus topology without disrupting other connected stations or sensors.
In a licensed production environment, single-condition device control is often too coarse. Exhaust fans tied only to temperature may short-cycle during dry conditions; CO2 systems wired only to a timer can continue running while fans are actively purging the room — wasting enrichment and throwing off VPD targets. The DCC-1 closes these gaps without requiring a full controller upgrade.
Typical commercial applications include: exhaust fan activation on temp OR humidity breach, CO2 cutoff interlocked to active fan operation, night-cycle CO2 override logic, and heating device control gated by both a setpoint and a daylight condition. For cultivation teams standardizing on TrolMaster across multiple rooms or facilities, the DCC-1 is a low-cost way to add meaningful conditional logic to any station that would otherwise require a dedicated controller or custom relay wiring.

The DCC-1 is designed for use with TrolMaster's plug-in style device stations: DSC-1, DSH-1, DSH-2, DST-1, DST-2, DSP-1, DSP-2, DSV-1, and DSD-1. It connects to one of these modules via its built-in RJ12 cable and coordinates the second condition through the bus. Lighting control adapters (LMA series) are not in the confirmed compatibility list — verify your specific module against TrolMaster's current documentation before ordering.
Interlock OFF is parallel logic: either of the two paired conditions can independently trigger the connected device. Interlock ON is series logic: both conditions must be active at the same time before the device turns on or off. Choose OFF when you want the device to respond to whichever condition trips first. Choose ON when you need two simultaneous conditions to be met — for example, cutting CO2 only when exhaust fans are confirmed running.
No. The DCC-1 handles its own logic at the module level through the RJ12 bus. It is plug-and-play compatible with the existing Hydro-X platform — HCS-1, HCS-2 Pro, and HCS-3 Plus — without requiring a controller firmware update.
One device, two conditions. The DCC-1 does not split output to two separate devices. It bridges two plug-in modules together so that one connected device station acts on the combined logic of both. If you need to control multiple independent devices from multiple conditions, you would use additional device stations and, if needed, additional DCC-1 adapters.
Yes, with one DCC-1 per device station pairing. Each DCC-1 operates at the individual module level, so in a multi-room or multi-zone facility running separate Hydro-X controllers, you would deploy one DCC-1 per room per application where dual-condition logic is needed. The adapters do not communicate across controller units.
