), of type designation 60245 IEC 57 or heavier.
3 Solar pump cable shall be (2 x min 1.5 mm
2
), of type designation 60245 IEC 57 or heavier.
4 Pool pump cable shall be (2 x min 1.5 mm
2
), of type designation 60245 IEC 57 or heavier.
5 Room thermostat zone 1 and zone 2 cable shall be (4 x min 0.5 mm
2
), of type designation 60245 IEC 57 or
heavier.
6 Mixing valve zone 1 and zone 2 cable shall be (3 x min 1.5 mm
2
), of type designation 60245 IEC 57 or
heavier.
7 Room sensor zone 1 and zone 2 cable shall be (2 x min 0.3 mm
2
), double insulation layer (with insulation
strength of minimum 30V) of PVC-sheathed or rubber-sheathed cable.
8 Buffer tank sensor, pool water sensor and solar sensor cable shall be (2 x min 0.3 mm
2
), double insulation
layer (with insulation strength of minimum 30V) of PVC-sheathed or rubber-sheathed cable.
9 Water sensor zone 1 and zone 2 cable shall be (2 x min 0.3 mm
2
), double insulation layer of PVC-sheathed
or rubber-sheathed cable.
10 Demand signal cable shall be (2 x min 0.3 mm
2
), double insulation layer of PVC-sheathed or rubber-
sheathed cable.
11 SG signal cable shall be (3 x min 0.3 mm
2
), double insulation layer of PVC-sheathed or rubber-sheathed
cable.
12 Heat/Cool switch cable shall be (2 x min 0.3 mm
