Regulating the temperature in a warehouse

Application Details

When the temperature gets above a certain level the fans in a warehouse are turned on to regulate the temperature. The problem is that if the temperature is higher outside the warehouse, the fans bring in the warmer air. This defeats the point of the process.

Solution Provided

Using a programmable relay with 2 analogue inputs, intelligent temperature modules and PT100s, a small program using an analogue comparator can over ride the fans if the temperature is warmer outside than in.
