ReliaTel also provides outputs for building automation systems and expanded diagnostics. For a complete list of ReliaTel offerings, refer to Other Benefits, p. UnitsThe dedicated design units (either downflow or horizontal) require no panel removal or alteration time to convert in the field a major cost savings during installation. Horizontal units come complete with duct flanges so the contractor doesn t have to field fabricate them.

8 These duct flanges are a time and cost HeatersThese band or insertion heaters provide improved compressor reliability by warming the oil to prevent migration during off-cycles or low ambient conditions. These are standard on all voyager Line ThermostatA bi-metal element discharge line thermostats installed as a standard feature on the discharge line of each system. This standard feature provides extra protection to the compressors against high discharge temperatures in case of loss of charge, extremely high ambient and other conditions which could drive the discharge temperature or High Efficiency cooling available. CompressorsVoyager contains the best compressor technology available to achieve the highest possible performance. Dual compressors are outstanding for humidity control, light load cooling conditions and system back-up applications.

9 Dual compressors are available on all models and allow for efficient cooling utilizing three stages of compressor operation (high efficiency 12 20 Tons models only). 25 tons high efficiency units have 4 stages of cooling with a single compressor and tandem set (similar to variable speed).Easy Access Low Voltage Terminal BoardFoil Faced Insulation8 RT-PRC028AH-ENFeatures and BenefitsFork Pocket AccessVoyager has the ability to be forked from 3 requires the design t o b e t e s t e d t o 2 times this current standard. The drum and tube design has been tested and passed over 150,000 cycles, which is over 15 times the current ANSI cycling requirements. The negative pressure gas valve is used in the standard furnaces. This is one of our unique safety features. Modulating heaters use a pressure switch to ensure that the blower motor is operating before the gas valve is allowed to forced combustion blower supplies pre-mixed fuel through a single stainless steel burner screen into a sealed drum where ignition takes place.

10 It is more reliable to operate and maintain than a multiple burner system. Modulating furnaces contain a metal fiber material to ensure proper flame distribution at low fire. The hot surface ignitor is a gas ignition device which doubles as a safety device utilizing a continuous test to prove the flame. The design is cycle tested at the factory for quality and reliability. Our gas/electric rooftops exceed all California seasonal efficiency requirements and perform even better than the California NOx emission Ambient CoolingAll voyager microprocessor units have cooling capabilities down to 0 F as standard. voyager s Low Voltage Terminal Board is external to the electrical control cabinet. It is extremely easy to locate and attach the thermostat wire and test operation of all unit functions. This is another cost and time saving installation panels in the evaporator section of the unit have cleanable foil-faced insulation.
