Restrictions To Control System - Daikin VAM-FA8VE Technical Data Manual

• HRV • VKM-GA(M)V1
•
Structure without a remote controller cannot be accepted because the remote controller group is
controlled within a VKM-GA(M) model. (intelligent Touch Controller, central control controller)
Zone interlock setting : None
* Alteration of set temperature and independent ventilation operation cannot be performed from a central device.

10.4 Restrictions to Control System

10.4.1 Do not Give VKM-GA(M) Model a Function to Select Cooling/Heating.
(This is because the operation mode switches automatically depending on the outdoor
conditions regardless of the indoor temperature when set to "Automatic".)
10.4.2 Caution When Connecting with a VRVIII System, Heat Recovery Type
When bringing the RA (exhaust gas intake) of this unit directly in from the ceiling, connect to a BS unit
identical to the VRV indoor unit (master unit), and use group-linked operation.
SA
• The system must be operated interlocking
with the air conditioner.
If above setting is not made, the detection of correct temperature is not available and automatic judgment
on proper cooling or heating cannot be made when the temperature in the ceiling gets higher than indoor
temperature.
Poor heating or shortage of the amount of humidification may result.
If the indoor unit and this unit are installed with different BS system inevitably, always take following
remedies (1) and (2).
(1) RA (Exhaust and suction) of this unit is not taken directly from inside of the ceiling, connect the suction
duct and suction grille to the fitting port of RA duct to suck the indoor air.
SA
(2) Do not make the selection of heating or cooling in automatic mode and it shall be made by manual
selection from remote controller or centralized controller.
