NOTES:
1. The heating sequence output is set to Direct Acting (default). This is typically used for normally open valves.
Output can be set to reverse acting by changing the MIN and MAX value.
2. The cooling sequence output is set to Direct Acting (default). This is typically used for normally closed valves.
Output can be set to reverse acting by changing the MIN and MAX value.
