3.6.2 BP Unit Command Conversion
1. ∆D (room temperature − temperature setting) signals from BP units are converted to α
values.
∆
D signals from BP units are used as the
α
value in frequency commands (excludes when
Powerful function is in operation).
2. Processing during Powerful operation mode
(1) When Powerful command is received from indoor units (one or more units)
(2) Thermostats are not OFF in room units from which Powerful commands are issued
When the above conditions are met, the Powerful operation mode is activated, and the
following processes are conducted.
(3) Based on the
α
value determined by
∆
D signal from indoor unit, the following calculation is
performed.
α
value =
α
value +
α
PWR
3. Determination of S value
There are two types of indoor unit capacities from individual BP units. One is the
Σ
S value of the
connected indoor unit, and the other is the
Σ
S value of the indoor unit which receives an
operation demand for the same mode as that of the outdoor unit. They are called H/U
connection
Σ
S value and BP operation
Σ
S value, respectively. The sums of those S values of
BP units are called outdoor unit connection
Σ
S value and outdoor unit operation
Σ
S value.
In this manual, outdoor unit connection
Σ
S value is referred to as
Σ
S value, and outdoor unit
connection
Σ
S value is referred to as
Σ
S value.
