Confusion setting a timer

[krementz]

I feel foolish since this seems so straightforward. Any help for this newbie appreciated. Running HS3 Pro Edition 3.0.0.435 (Linux) on hometroller SEL

I want a pump to run for three hours when the water is too hot. My system of tanks and non-controllable heat sources (wood stoves) means there are sometimes significant stratification and varying temps across the tanks.

How do I program the following?

If WaterTemp => 160, Run RecircPump for 3 hours [regardless of water temperature during the 3 hours]

Turn Off electric heaters

If after 3 hours WaterTemp < 160, Stop RecircPump, exit

If WaterTemp => 160, Run RecircPump until WaterTemp < 155, exit

Timers in HS3 work as an actual Timer. Think of a Stop Watch or the time command on unix. They count UP not DOWN.

You would set your event to when time equals 3 hours or to be greater than 3 hours.

Seems like you can do this without timers. Two events:

Event 1 - use trigger "This device had its value set and is greater than"
IF WaterTemp was set and has a value that is greater than 159
AND IF RecircPump has a value equal to Off
Then set RecircPump ON

Event 2 - use trigger "This device has been/for at least..."
IF RecircPump has been On for at least 3 hours
AND WaterTemp is less than 155
THEN set RecircPump OFF

Thank you both. I set it up with two events, and will try to test it when I can light a fire. A little warm today...
