Centralised control of the VRV
®
system can be achieved via 3 user
friendly compact controls: centralised remote control, unified on/off
control and schedule timer. These controls may be used independently
or in combination where 1 group = several (up to 16) indoor units in
combination and 1 zone = several groups in combination.
A centralised remote control is ideal for use in tenanted commercial
buildings subject to random occupation, enabling indoor units to be
classified in groups per tenant (zoning).
The schedule timer programmes the schedule and operation conditions
for each tenant and the control can easily be reset according to varying
requirements.
