Setting item Function
L.SV Low set value Set lower limit.
M.SV Middle set value Set median.
H.SV High set value Set upper limit.
Lu Low limit deviation setting Set lower limit offset.
Hd High limit deviation setting Set upper limit offset.
T1~T4 Temperature 1~4 Zone setting by temperature-side group (Group 4)
H1 H Zone setting for humidity side (Group 1)
Zone separation Description
Zone A (PV≥H.SV) Always OFF regardless of offset
Zone B
(M.SV≤PV≺H.SV)
1) Hd=0(Always OFF regardless of offset)
2) Hd≠0(Refer to Fig. 91). OFF : PV≺SV+Hd ON : PV≥SV+Hd
Zone C
(L.SV≤PV≺M.SV)
1) Lu=0(Always ON regardless of offset)
2) Lu≠0(Refer to Fig. 92). OFF : PV≤SV-Lu ON : PV≻SV-Lu
Zone D (PV≺L.SV) Always OFF regardless of offset
By L.SV, M.SV, and H.SV, the range has 4 zones: A, B, C, and D.
Setting condition is L.SV < M.SV < H.SV.
