15 Control systems
15 - 3 Basic patterns
15 - 3 - 2 Independent system
Control with two remote controls
Purpose and functions
• For control of one HRV unit (Also one group control is
possible)
Sophisticated operation and indication output are possible
from either local place or remote place by two liquid crystal
remote controls.
• Either one of two liquid crystal remote controls can be used
for all operations and indications.
(However, initial setting can only be carried out by the
master remote control)
Point
• The wiring to the remote controls must be branched from the
unit as shown in the diagram.
(Though the crossover between the master and slave
remote controls is acceptable, the work to put two wires into
the remote control takes time.)
Group control
Purpose and functions
• Simultaneous control of multiple HRV units (max. 16 units) is
available (for application to such as a spacious room)
• All operation and individual setting can be carried out from
one remote control.
• In case the liquid crystal indicates malfunction, the indication
of HRV unit No. shows in the display.
(If another remote control is additionally installed, control
with two remote controls is possible.)
Point
• No address setting is required because address is
automatically set.
(The address is optionally allocated. The address No. can
be confirmed by setting to service mode "Forced fan
operation" and be checked whether the unit is in operation
or not.)
• Heat reclaim ventilation • VAM-FA/FB
• Ventilation • Heat reclaim ventilation
