Humidistat Station, for Dehumidifier with 24V terminal

Switch Commercial Dehumidifiers Through a Low-Volt Connection

The TrolMaster HS-1 humidistat station lets your Hydro-X system control a commercial dehumidifier through its low-voltage control input instead of switching the unit's full power load directly.

Routing control through the 24V terminal avoids the high inrush current that larger dehumidifier compressors draw on startup, which helps protect both the device station and your dehumidifier's control circuit.

Key Features & Benefits

• Low-Voltage Switching — Operates through a 24V control terminal rather than full line voltage.
• Hydro-X Integration — Connects to any Hydro-X controller using a standard RJ12 cable set.
• Inrush Current Protection — Avoids directly switching high-draw compressor startup current.
• Compact Station Design — Fits into a single device module slot on supported controllers.

Who Should Use the HS-1 Humidistat Station

Growers running commercial-grade dehumidifiers with a low-voltage control input will want the HS-1 to integrate that equipment into a Hydro-X automated control schedule.

Confirm Your Dehumidifier's Control Input

Before installing the HS-1, check that your dehumidifier has a compatible low-voltage (24V) control terminal. Units that only accept direct line-voltage switching require a different TrolMaster device station.

Frequently Asked Questions

Does the HS-1 switch full line voltage?

No. It switches through the dehumidifier's 24V control terminal, not the unit's main power line.

What cable does the HS-1 use?

It connects to the Hydro-X controller with a standard RJ12 cable set, included with the station.

Why use low-voltage switching?

It avoids the high inrush current that larger compressors draw on startup, reducing wear on your control equipment.

Can the HS-1 work with any dehumidifier?

It works with dehumidifiers that offer a 24V low-voltage control input; check your unit's specifications before purchase.
