The lead ASHP is enabled when sensor 5 (from the top of the thermal store) of Thermal Store 3 falls below 53°C for 2 minutes – to be finalized during load test.
The lead ASHP is disabled when sensor 4 (from the top of the thermal store) of Thermal Store 1 rises above 50°C for 2 minutes – to be finalized during load test.

How can I implement an interlock in a Niagara 4 wire-sheet to ensure that both scenarios cannot operate simultaneously?

Maybe something like an AND block into the enable. For inA you need a LessThan block with the input from the sensor and the setpoint and a boolean delay. For inB, GreaterThan and a Not…or just use a LessThan again and boolean delay. That doesn’t give you any deadband…if you want that you could use Tstat blocks
