& common
ELECTRONIC EXPANSION VALVE (EEV)
› Expansion valve is electronically operated for precise control of refrigerant flow into the evaporator
› Greater efficiency due to better superheat control2
› Enables fast & accurate response to heat load changes
DUAL FIXED SPEED SCROLL COMPRESSORS
› 2 step control, 50 & 100% capacity
› Compressor balance loading function, ensures the accumulated run time of each compressor is
similar to extend compressor longevity
HYDROPHILIC BLUE FIN HEAT EXCHANGER (OUTDOOR)
› Aluminium corrugated (waffle) fins with Ø7mm copper pipes
› Dual heat exchangers each with 2 rows3 at 16 fins per inch
› PE coated – an acrylic & hydrophilic coat for corrosion resistance

Built-in Demand Response (DRED)
Designed to enable electricity providers to reduce peak demand, when necessary, RT Series rooftop packaged units feature built-in DRED contacts. -
Electronic Expansion Valve (EEV)
For precise control of refrigerant flow, RT Series is equipped with an EEV, enabling fast & accurate response to heat load changes. -
Sequential Defrost Operation
The dual outdoor heat exchangers (HX) allow each HX to enter defrost cycle separately* for improved comfort as reduced heating capacity can still be provided to the indoor environment. -
Engineered for ease of installation
The all-in-one IP44 rated electrical box allows quick and easy access to components such as power supply terminals, RT Touch Controller terminals, after-hours pushbutton contacts and DRED contacts.
*Only applicable when indoor fan is set to run during defrost (default setting), if fan set to off both heat exchangers will run defrost simultaneously
› Footprint ideal for replacement market
› Indoor EC plug fan (fixed speed control only), adjustable with up to 300Pa ESP increase over rated
› EC motor driven outdoor propeller fans with ESP of 30Pa
› Dual fixed speed scroll compressors (2 step, 50 & 100% capacity)
› Hydrophilic blue fin indoor & outdoor coils
› Foil faced 20mm PE Thermobreak insulated panels
› Built-in 2” return air filter rails with MERV 8 filters
› Built-in demand response (DRED) capability
› After hours push button is included
› Optional vibration mounting kit & remote temperature sensor (25m)
› Built-in economy cycle function (dry bulb only)*
Sequential Defrost Operation
The dual outdoor heat exchangers allow each heat exchanger to enter defrost cycle separately**. If both heat exchangers require defrost, the 2nd heat exchanger will enter defrost cycle once the first one is
completed. Improves comfort as reduce
