• Control systems
• Centralised control systems • Centralised remote control/Unied ON/OFF / Schedule timer
Centralised control of the VRV system can be achieved via 3 user
friendly compact controls: centralised remote control, unied on/o
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
classied 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.
