The TrolMaster HS-1 Humidistat Station is designed to control compatible commercial dehumidifiers equipped with a low-voltage external humidistat connection.

Instead of switching the dehumidifier’s main electrical power ON and OFF, the HS-1 connects to the unit’s low-voltage control terminals. This allows your TrolMaster environmental controller to manage dehumidification according to your programmed humidity settings while the dehumidifier remains connected to its normal power source.

The HS-1 integrates with compatible Hydro-X controllers and is ideal for commercial grow rooms using professional dehumidifiers with dedicated external humidistat terminals.

Frequently asked questions

Does the HS-1 power the dehumidifier?

No. The dehumidifier remains connected to its normal electrical supply. The HS-1 controls the low-voltage humidistat circuit.

Can the HS-1 control a 240V dehumidifier?

Yes, as long as the dehumidifier has a compatible low-voltage external humidistat connection.

Does the HS-1 measure humidity?

No. Humidity is measured by the environmental sensor connected to the TrolMaster controller.

Should I use an HS-1 or a DSH Device Station?

Use the HS-1 when your dehumidifier has a low-voltage humidistat input. Use a DSH Device Station when the equipment must be controlled by switching its electrical power ON and OFF.

Is the HS-1 compatible with every commercial dehumidifier?

No. The exact dehumidifier must have a compatible external low-voltage humidistat connection.
