SETTING AND USING METHOD
ENGLISH
CAUTION
• This input can accept only non voltage
contact.
Do not input external power source.
Otherwise it will cause a serious dam-
age.
• If the contact point is attached, capacity
control is applied preferentially by TMS
system.
• If the NLO contact point is attached,
System is operated preferentially than
outdoor unit setting.
!
2. Using Demand control function with 0~10V
DC Voltage signal.
With this function comp capacity of outdoor
unit can be controlled by BMS.
Ex) Demand control by Analog input signal
Refer to detail of the control step for ana-
log input signal.
3. Operation Status.
①
Error Display
: This Module display error signal as below.
- Level 1,2 error of Outdoor Unit
- Indoor Unit error _ All IDU Error.
②
Operating Display
: This function is depend on 4th Dip SW
setting of ‘SW101’.
- L4 is ON : Display Indoor Unit operat-
ing status (Include FAN mode only)
- L4 is OFF : Display Outdoor Unit oper-
ating status (Compressor operating
condition)
CAUTION
• This function is very sensitive to voltage
level.
So when using analog input, make a sig-
nal cable as short as possible.
• Do not change a command too quickly.
Keep the command 30 seconds at least,
otherwise it will cause a damage to out-
door unit.
