The Summer Winter Mode module is designed to switch a unit that controls a two-pipe coil between summer and winter operation based on the supply water temperature. This module accepts supply water temperature, setpoint, and differential as inputs. The module has a state output. If the supply water temperature is greater than the setpoint, the unit operates in the winter mode; and if the supply water temperature is less than the setpoint (with a differential), the unit operates in the summer mode. The module uses the last reliable water temperature when the water temperature becomes unreliable.
You can view and modify the modules in this group’s logic.
