(1) Energy saving control for indoor unit
For the energy saving control for the indoor unit, select the time portion to be applied to the energy
saving control items listed in Table 9-2 from 0/3/6/9/15/30 minutes. By dividing those items by the group
numbers in the operation block evenly, the energy saving control is applied to the groups starting from
that with smaller group number in order. When “30 minutes stopping” is being applied to save energy,
ON/OFF operation can not be performed by any controller.
Notice
In the case of the block setting stepped across from TG-2000A to G-50A, only the unit
controlled by the G-50A is set as the block on the G-50A.
Here each G-50A applies rotation control to each group inside the block.
When the fan/thermostat OFF control is selected, Free Plan models and A-control
Slim models are provided with the thermostat OFF (capacity saving control)
command, while K-control models with the fan mode switching.
As the mode display of the local remote controller does not change, energy saving
control can be performed without the perception of occupants.
Setting of the energy saving ineffective temperature difference allows not applying the
level 0 control to the block with the temperature difference between inlet and set
temperature exceeding the set value.
Operation control from Web browser or TG-2000A provides the screen display of [ON]
for 1 minute maximum but not allowing to run the air conditioner.
[In case of the energy saving control of indoor unit for 6 minutes when 5 groups is in one block for
example]
1 Times of rotation:
For the control of 6 minutes, 3 minutes control is applied for 2 times (= 6 min./3 min.).
2 Cycles of rotation:
From the times of rotation in 1, the cycle of rotation for 30 minutes is to be 15 minutes (= 30
min./2 times)
3 Intervals of rotation:
From the cycles of rotation in 2, the rotation interval of each group in a block counts for 3 minutes
(= 15 min./5 groups). (If indivisible, round it to the nearest whole number.)
