If Output Pump1 = ON Then ON

Then add this line to the bottom your existing heater outputs:
If Output Pump_Status = OFF Then OFF
Basically, the virtual output will be turned On if either Pump1, Pump2, or both pumps are On. If they're both Off, the virtual output will remain Off, and this will then prevent the heaters from running regardless of the temperature logic above this new line of code.
