Q. Can HVAC2 Work without need to purchase DDP?

A. Yes, the new HVAC2 (G4) is designed to work as stand alone as well as networked, it can read from its built in aux-port Temp sensor, and can receive its settings and temperature desired from BMS or automation control Software for Commercial centers and open offices, or hotel lobby applications..etc)

Q. what systems can the HVAC2 control?
A. HVAC2 can control any HVAC unit type like FCU, AHU. Or even VAV 0-10V. (good for Split ducted, Package, Desert Coolers, Chillers, VAV ++)

Q. Can HVAC2 Control different fan speeds?
A. Yes, HVAC2 has 3 Fan speed relays built in. (high, Mid, Low)

Q. Can HVAC2 Control Heat Pump HVAC type, or multistage type?
A. Yes, the new HVAC2 (G4) is designed to work with both types, and to handle single and multistage (2-3 AC cooling units).

Q. How can we control IR operated Systems like Split AC?
A. Simply by using Smart-BUS IR emitter (SB-IR-UN)
