Setting a Deadband (Two-Stage) Control: LAE AC1-5 Digital Controller

The AC1-5 digital controller from LAE Electronic has two relays, which can be used to set up a deadband control or two-stage control. In this example, we show how to set the relay parameters for a deadband of 4 degrees. This means heating will begin when the temperature falls below the set point by 2 degrees and cooling will start when the temperature rises above the set point by 2 degrees. This includes setting the correct relay modes, differential temperatures, minimum on and off times and set points. Got a further question about programming an LAE controller? We can help.
