If the temperature is below setpoint, the output will be on longer; if the temperature is too high, the output will be off longer. without altering the cabinet. At the setpoint (the midpoint of the proportional band), the output on:off ratio is 1:1; that is, the on-time and off-time are equal. The right amount really depends on your growing amounts and location, so be sure to check to make sure youre using the right amounts for your own plants. PID Control The proportional, integral and derivative terms must be individually adjusted or "tuned" to a particular system using trial and error. Thus, with no change in vapour content, the relative humidity of the air has fallen from 100 to only 53 percent, illustrating why relative humidity does not identify air masses. This is warm enough to keep the plants happy, but not hot enough to make them shrivel up. Controllers can be configured to drive duel, single variables processes depending on your needs.
