|
Radiator* – Control sequence: Heating only (P01 = 0)
|
Chilled / heated ceiling* – Control sequence: Changeover (P01 = 2,3)
|
Chilled ceiling* – Control sequence: Cooling only (P01 = 1)
|
|
| 2-pipe and electric heater | 2-pipe fan coil unit with electric heater – Control sequence: No impact (P01 = any)
|
Single stage with electric heater – Control sequence: No impact (P01 =any)
|
| 4-pipe | 4-pipe fan coil unit – Control sequence: Not auto c/o (P01 <> 3)
|
