I re-read this:

Why cut the heat automatically when the mash is over? There's no harm in mashing longer (you'll just get better conversion). I would just have an alarm go off when the mash is done but not change the heat.

Normally at the end of mash you want to raise the temp to mashout. If you cut the heat, the temp will slowly drop over time. If you're delayed in getting to the setup to go to mashout you'll have to heat more.

If anything maybe have the temp go UP to mashout when the time runs out instead?

Just food for thought!

I have this pid. I have not been able to get the timer to work during manual mode. Once in manual mode, the only display is the manual setting and the process value.

Kal,

Thanks for the food for thought. I went back through the manual again and noted that INT parm controls the function of the timer and relay.

These are not categorized in the manual, but I've added some headers to help me see the differences.

0= Timer disabled

Single Timer modes with Heat Control Options
1= Timer starts when temp reached. When set time is reached, controller stops heating and timer (alarm) relay pulls in.
** This is what I have it set to.

2= Timer starts when temp reached. When set time is reached, timer (alarm) relay pulls in and controller continues to heat.
** This would be the better setting, as you suggested earlier.

3= Timer starts when temp reached. Timer relay pulls in when timer starts and drops out when it reaches the set time.
** I'm not sure how you might use this except to maybe run a light indicating the circuit is active

Independent Timer Functions
4= Timer function is independent of temp controller. After powered up or reset, the relay pulls in when time reaches the set time.
** This function could be used for the timer for the BK for hop additions.

5= Timer function is independent of temp controller. After powered up or reset, the relay drops out (opens) when time reaches the set time.
** Similar to #3 above?

Dual Timer Functions
6= Timer function is independent of temp controller. After powered up or reset, the relay T1 drops out (opens) then T2 pulls in when time reaches the set time. (Dual timer cycling mode)

7= Timer function is independent of temp controller. After powered up or reset, the relay T1 drops out (opens) then T2 pulls in when time reaches the set time. (Dual timer no cycling mode)

8= Timer function is independent of temp controller. After powered up or reset, the relay T1 pulls in (closes) then T2 drops out (open) when time reaches the set time (Dual timer cycling mode)

The dual timer functions could possibly be used for timing hop additions, except that there is no alarm to externalize when the 2nd timer expires - just a light on the front of the PID that turns on.

With this additional information I'll probably use INT=2 for the RIMS PID and INT=4 for the BK. But I don't think this timer is active when in Manual Mode. A note to Auber might get me squared away.

One thing extra I found out is that if you start the timer then change to manual mode, the timer is still running. When you go back to automatic mode the timer's current value is then displayed and the timer is stopped.

For instance, I set the timer to count up from 0 to 30 seconds then put it in manual mode. When the 30 seconds was reached the alarm did not go off. This is what everyone else has stated so no surprise there. However, when I changed modes back to manual I noted the timer had 42 seconds on it. So the timer circuit is still running, but the checking for the timer expiration and ability to trigger the alarm relay are deactivated.
