Control of the saturation temperature with preheating coil and dampers.
Return temperature control with cooling ad reheating coil.
Dampers control comparing return and outside temperature
Fig 28_ [Examples - Example 1]
Dampers
D01 – control probe = tH1 (preheat probe)
D02 – freecool setpoint selection = FRH (connected to the freeheat sequence).
D03 – freeheat setpoint selection = LS1 (saturation temperature setpoint)
D07 – changeover probe 1 = RET (return probe)
D08 – changeover probe 2 = OUT (outside probe)
Preheating coil
b10 – coil 1 function = HS1 (heat sequence 1)
H11 – control probe = tH1 (preheat probe)
H12 – setpoint selection = FRH (connected to the freeheat sequence)
