Here is my current code... This code turns on a recirculating pump to my water heater.
Fallback OFF
If Tmp < 76.8 Then ON
If Tmp > 77.2 Then OFF
If Tmpx5 < 76.8 Then ON
If Tmpx5 > 77.2 Then OFF
I have 2 sumps for two separate tanks.. both are heated using pex tubing and a shared recirc pump. I have solenoids that open to direct the heat to the corresponding sumps and that works just fine.. problem is that the recirc pump will not turn on if one of the tanks is above 77.2 degrees.. example.. Tmp can read 77.4 and Tmpx5 can be 76.7.. the recirc pump will not turn on until Tmp probe drops below 76.8 as well.. What code would I need to make sure that the recirc pump will turn on if either probe is below 76.8?? Thanks!
