Install an approved accessory 2 stage Cooling/Heating thermostataccording to installation instructions included with the accessory.The RHS models do not require a thermostat with an O function tocontrol the reversing valve operation. If using an electronicthermostat, configure it for “non−heat pump” operation. Locate thethermostat accessory on a solid wall in the conditioned space tosense average temperature in accordance with the thermostatinstallation instructions.

If the thermostat contains a logic circuit requiring 24−v power, usea thermostat cable or equivalent single leads of different colorswith minimum of seven leads. If the thermostat does not require a24−v source (no “C” connection required), use a thermostat cableor equivalent with minimum of six leads. Check the thermostatinstallation instructions for additional features which might requireadditional conductors in the cable.

For wire runs up to 50 ft. (15 m), use no. 18 AWG (American WireGage) insulated wire (35�C minimum). For 50 to 75 ft. (15 to 23 m),use no. 16 AWG insulated wire (35�C minimum). For over 75 ft.(23 m), use no. 14 AWG insulated wire (35�C minimum). All wiresizes larger than no. 18 AWG cannot be directly connected to thethermostat and will require a junction box and splice at thethermostat.

Electric Heaters

RHS units may be equipped with field−installed accessory electricheaters. The heaters are modular in design, with heater framesholding open coil resistance wires strung through ceramicinsulators, line−break limit switches and a control contactor. One ortwo heater modules may be used in a unit.Heater modules are installed in the compartment below the indoor(supply) fan outlet. Access is through the indoor access panel.Heater modules slide into the compartment on tracks along thebottom of the heater opening. See Fig. 22, Fig. 23 and Fig. 24.

Not all available heater modules may be used in every unit. Useonly those heater modules that are UL listed for use in a specificsize unit. Refer to the label on the unit cabinet for the list ofapproved heaters.Unit heaters are marked with Heater Model Numbers. But heatersare ordered as and shipped in cartons marked with acorresponding heater Sales Package part number. See Table 2 forcorrelation between heater Model Number and Sales Package partnumber.NOTE: The value in position 9 of the part number differs betweenthe sales package part number (value is 1 or 3) and a bare heatermodel number (value is 0).

Single Point Boxes and Supplementary Fuses — When the unitMOCP device value exceeds 60−A, unit−mounted supplementaryfuses are required for each heater circuit. These fuses areincluded in accessory Single Point Boxes, with power distributionand fuse blocks. The single point box will be installed directlyunder the unit control box, just to the left of the partition separatingthe indoor section (with electric heaters) from the outdoor section.The Single Point Box has a hinged access cover. See Fig. 25.The Single Point Box also includes pigtails to complete the wiringbetween the Single Point Box and the unit’s main control boxterminals.

Legend and Notes

LEGEND:CO − Convenient outletDISC − DisconnectFLA − Full load ampsIFM − Indoor fan motorLRA − Locked rotor ampsMCA − Minimum circuit ampsMOCP − Maximum over current protectionPE − Power exhaustUNPWR CO − Unpowered convenient outletNOTES: 1. In compliance with NEC requirements for multimotor

and combination load equipment (refer to NEC Ar-ticles 430 and 440), the overcurrent protective devicefor the unit shall be fuse or HACR breaker. Canadianunits may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance insupply voltage is greater than 2%. Use the followingformula to determine the percentage of voltage imbal-ance.

% Voltage Imbalance = 100 xmax voltage deviation from average voltage

average voltage

Example: Supply voltage is 230-3-60

AB = 224 vBC = 231 vAC = 226 v

Average Voltage =(224 + 231 + 226)

=681

3 3

= 227

Determine maximum deviation from average voltage.(AB) 227 – 224 = 3 v(BC) 231 – 227 = 4 v(AC) 227 – 226 = 1 vMaximum deviation is 4 v.Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x4

227

= 1.76%

This amount of phase imbalance is satisfactory as it is below the maximumallowable 2%.IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-tact your local electric utility company immediately.
