Introducing the WPC-9 Multi-channel differential controller

The WPC-9 is a multi-channel temperature ambient differential controller. This unit is designed for monitoring and automatic controlling of temperature by operating ambient fans. Thus enabling the end user to keep potato and vegetable stores in ideal conditions. This unit can operate in either warming or cooling modes. Ambient differential settings prevent un-necessary use of the fans during unfavourable or marginal conditions. Up to a maximum of 8off crop temperature sensors can be fitted together with the ambient temperature sensor.

The WPC-9 system incorporates two separate units. Identified as the controller and the relay enclosure. The relay box is connected to the controller, as are the crop sensors, the ambient sensor, and the optional printer. All sensors are connected directly to the controller via 1/4" jack plugs. Outputs are provided via the relaycard. The relays provided are voltage free and are mounted in an enclosure.

The ZP-40 printer is an optional extra and has the ability to give a permanent record of the previous twenty-four hours performance.
