Zodiac – Hygro Control Digital Controller with Sensor

The Zodiac Hygro Control (WD000001) is a combined digital hygrostat and thermostat controller with integrated sensor, designed to regulate both humidity and air temperature in indoor swimming pool enclosures. It provides a clear digital display of current conditions and allows precise setpoint adjustment for the dehumidification and, where applicable, heating functions of compatible Zodiac indoor pool dehumidifiers. This is a genuine Zodiac/Fluidra spare part, also known as the HygroControl 2014.

Compatibility

This controller is compatible with an extensive range of Zodiac ducted and built-in dehumidifier units, including the CAE, DF, Omega, and Sirocco series. It fits all models listed in Fluidra exploded views W28CAE, W28DF, W28OM, and W28SI variants. It can also replace older-generation mechanical hygro-thermostat units, provided the dehumidifier is equipped with a compatible ECP600 regulator board. Always verify your model reference before ordering.

Why genuine matters

As the primary control interface between the user and the dehumidifier, the Hygro Control unit must operate reliably in a humid, chlorinated environment. Using a genuine Zodiac part ensures correct voltage compatibility (12 Vac), accurate sensor calibration across the full operating range (0–90% humidity, 0–55°C admissible room temperature), and safe integration with the ECP600 control system — giving you confidence in both comfort and building protection.

Installation

The Hygro Control mounts in the pool hall as a remote wall-mounted panel, connected back to the dehumidifier unit via the dedicated low-voltage terminals on the ECP600 regulator. Humidity setpoints are adjustable between 55% and 70% (comfort default: 65%), and temperature between 5°C and 32°C (comfort default: 28°C). Installation and wiring should be carried out by a qualified HVAC or pool technician.
