Humidistat Station, for Dehumidifier with 24V terminal

Switch a Commercial Dehumidifier Through Its Low-Voltage Input

Switching a commercial dehumidifier's full compressor load directly through a device station risks nuisance tripping and added wear from the high inrush current those compressors draw at startup. The TrolMaster HS-1 Humidistat Station sidesteps that by controlling the unit through its low-voltage 24V control terminal instead of its main power line.

It ships with a standard RJ12 cable set for connecting to any Hydro-X controller, occupying a single device module slot once installed.

Key Features & Benefits

• Low-Voltage Control Path — switches through a 24V terminal rather than the dehumidifier's main power line.
• Hydro-X Compatible — connects to any Hydro-X controller with a standard RJ12 cable set.
• Reduced Startup Stress — avoids routing high inrush current through the device station.
• Single-Slot Footprint — occupies one device module position on a Hydro-X controller.

Who Should Use the HS-1 Humidistat Station

Commercial growers running dehumidifiers equipped with a 24V low-voltage control input are the intended users of the HS-1, since it needs that terminal to operate. Confirm your dehumidifier offers that control option before ordering, because units limited to direct line-voltage switching call for a different TrolMaster device station instead.

About TrolMaster

TrolMaster builds a wide range of device stations from its Sacramento, California headquarters so a Hydro-X system can reach equipment that would otherwise need its own separate control path. The HS-1 fills that role specifically for humidity equipment wired for low-voltage operation.

Frequently Asked Questions

Does the HS-1 switch a dehumidifier's full line voltage?

No. It switches through the dehumidifier's 24V control terminal instead of the unit's main power line.

How does the HS-1 connect to my controller?

With a standard RJ12 cable set included with the station. It plugs into any Hydro-X controller's device module slot.

Why route control through a low-voltage terminal?

It avoids passing a compressor's high startup inrush current through the device station itself. That reduces wear on both the station and the dehumidifier's own control circuit.

Will the HS-1 work with any commercial dehumidifier?

Only ones equipped with a 24V low-voltage control input. Check your unit's documentation for that terminal before purchase.
