I'm looking at the Auber SWA-24x1 controller for a RIMS build. The feature that has me interested is the timer mode where the timer counts down a pre-determined time and then kicks off the PID control. This would allow me to setup my mash water the night before and have the system kick on before I get up. In the morning, I can roll out of bed, scratch, head downstairs and dump my grain into the mash tun and start the mash. This would eliminate a sizable chunk of time out of my brew day.
The question I have is can the Auber SWA-24x1 really do this? The website indicates that the timer has 3 modes which interact with the controller and 5 timer modes which are independent. One of the timer modes is described on the website as: "The third mode delay the heating until the time is reached. It starts the timer when powered up. When time is reached, the relay pulls in and heater starts."
When I read the user manual, it describes 3 timer modes which interact with the controller:
1. The timer starts after the temperature reaches set point. When set time
reaches, controller s output stops and timer relay pulls in (turns on). It can be
connected to a buzzer to warn the operator.
2. The timer starts after the temperature reaches set point. When set time
reached, relay pulls in. The controller s output will continue to be on.
3. The timer starts after the temperature reaches set point. When set time
reaches, controller s output stops. Relay pulls in when timer starts and drops
out when it reaches the set time.
All 3 modes start the timer after the temperature reaches the setpoint. No mode is listed where the PID kicks in after the timer expires. Does anybody have experience with this controller? I question the user manual because there is very little difference between mode 1 and 3.
