    3/4 down the longest duct run. Single Zone Variable Air Volume (SZVAV) – TempMaster OmniElite units are available for single zone variable air volume (SZVAV) applications. Control can be used with a zone sensor or a BAS.
  • Page 8 MS/TP (RS-485) Communications – This communication option is standard on ® every TempMaster OmniElite unit. Communications to the unit are through a twisted pair, and the wire terminations are on the primary unit control board. See supplemental infor- mation for the available control points and protocol implementation conformance state- ment (PICS)/BACnet interoperability building blocks (BIBBs) statements of conformity.
  • Page 9 Remote Terminal Unit (RTU) Communications – This communication option ™ is standard on every TempMaster OmniElite unit and can be used in lieu of the BACnet communications (only one can be used at a time). See supplemental information for the available control points.
  • Page 10 The speed of the supply fan is controlled by a VFD. EVAPORATOR SECTION Double Sloped Stainless Steel Drain Pan – The TempMaster OmniElite’s stainless steel drain pan is factory-mounted and installed on every unit. A condensate drain trap is need- ed and must be provided and installed in the field by others.
  • Page 11 Additionally, due to a three independent circuit design with two compressors on each circuit, the TempMaster OmniElite can provide superior granularity in terms of staging, which translates to best in class part load efficiency or IEER.

  • Page 14: Application Data

    Unit clearances are designed so that technicians have enough space between units, building walls, and edges of building to gain access safely. In cases where space is limited, please call a local TempMaster representative for additional infor- mation.
  • Page 15 Erecting a fence around the unit is common practice. • Roof curb – TempMaster offers optional roof curbs designed specifically for the TempMaster OmniElite footprint. These curbs come in full perimeter or open con- denser models and are shipped disassembled and require field assembly and instal- lation.
  • Page 16 If the application calls for horizontal supply and return air, TempMaster can ship it from the factory as a horizontal unit. This option eliminates the need for field modification of equip- ment saving time and money.
