131001-YUM-A-12052 Unitary Products GroupSECTION III: PROGRAMMABLEELECTRONIC THERMOSTATSThe computerized electronic thermostat is actually a sophisticated elec-tronic version of a manual change-over type. This thermostat includesfeatures which allow “set-back” temperature variations for periods ofsleep, or while you are away during the day, and means energy savingsfor you. The thermostat also features a digital clock.FAN OPERATION SELECTIONA multi-position fan switch allows you to choose the type of fan opera-tion of the indoor fan.AUTOWith the thermostat fan switch set to “AUTO”, the fan will run intermit-tently as required for either heating or cooling. This position will providethe lowest operating cost. If you purchased one of our thermostats, theyhave an Intelligent fan mode which continually circulates the air duringoccupied modes or when you are at home, and can cycle the fan duringunoccupied mode or during the night while you sleep to further con-serve energy.ONCONTINUOUS FAN OPERATION: With the thermostat fan switch set to“ON”, the indoor fan will not shut off. However, the cooling (AC) or heat-ing (electric heat) systems will still operate as required by room temper-atures. This provides continuous air filtering and more eventemperature distribution to all conditioned spaces.FAN ONLY OPERATION: On moderate days, usually during spring andfall, when neither heating nor cooling is required, you may want to runonly the fan to ventilate, circulate and filter the air in your home or build-ing. Set the comfort control switch to “OFF” and the fan switch to “ON”.Be sure to return the switches to their original positions for normal oper-ation.SECTION IV: START-UPThe comfort control switch is assumed to be in the “OFF” position. If themain power supply to the unit is off, turn the appropriate disconnects tothe “ON” position. Place the system into operation as follows:1. Set temperature adjustment to the desired temperature on yourthermostat.COOLING - The higher the setting, the lower the amount of energy con-sumed. Federal Guidelines recommend a setting of 78 °F.HEATING - The lower the setting, the lower the amount of energy con-sumed. Federal guidelines recommend a setting of 65 °F or lower.NOTE: If your cooling and heating temperature adjustments are sepa-rate, be sure to set both.2. After considering “Fan Operation Selection” above, select and setthe fan operation mode you desire.3. Move the comfort control switch to the desired mode of operation(Cooling or Heating) found on your particular thermostat.POWER FAILUREWhen accidents, wind storms, etc. disrupt electrical power supply toyour house, switch thermostat to “OFF” position.SECTION V: SYSTEM OPERATIONMANUAL CHANGE-OVER THERMOSTATCOOLING YOUR HOME: With the comfort control switch in the“COOL” position, the system will operate as follows: When the indoortemperature rises above the level indicated by the temperature adjust-ment setting, the system will start. The unit will operate and the fan willcirculate the cooled, filtered air. When the room temperature is loweredto the setting selected, the system will shut off.HEATING YOUR HOME: If your system includes a electric heat sectionand the comfort control switch is in the “HEAT” position, the system willoperate as follows: When the indoor temperature drops below the levelindicated by the temperature adjustment setting, the system will start.The heating system will operate and the fan will circulate the filtered air.When the room temperature rises to the setting selected, the systemwill shut off. Whether heating or cooling, the fan will continue to operateif the fan switch was set in the “ON or Intelligent” position. The “AUTO”setting on the fan switch will allow the fan to shut off when your systemdoes.ELECTRONIC THERMOSTATThe computerized electronic thermostat, when programmed, will func-tion automatically to operate the system as follows: When the indoortemperature rises above the higher (COOL) setting, the unit will operateand the fan will circulate the cooled, filtered air. When the room temper-ature is lowered to the selected level, the system will shut off. Theindoor fan will either shut off or run continuously, depending upon yourchoice of fan switch setting. When the indoor temperature drops belowthe lower (HEAT) setting, the heating system will operate, and the fanwill circulate the heated, filtered air. When the indoor temperature risesto the selected setting, the system will shut off. The indoor fan will eithershut off or run continuously, depending upon your choice of fan switchsetting.SECTION VI: CARE OF SYSTEMIt is strongly recommended that regular periodic preventative mainte-nance be performed on this equipment. The person most familiar withthe equipment in your H.V.A.C. system is a dealer. The dealer canensure your maintenance program meets the conditions of the War-ranty”, maximize the efficiency of the equipment, and service your unitwithin the federally mandated guidelines with regard to unlawful dis-charge of refrigerants into the atmosphere.COIL CAREKeep the outdoor unit free of foliage, grass clippings, leaves, paper, andany other material which could restrict the proper air flow in and out ofthe unit. The coil may be vacuumed to remove any debris from betweenthe fins. If the coil becomes excessively dirty, turn the main disconnectswitch to “Off” and wash the coil with your garden hose. Avoid gettingwater into the fan motor and control box. Flush dirt from base pan aftercleaning the coil.FIGURE 1: PROGRAMMABLE ELECTRONIC THERMOSTATFIGURE 2: PROGRAMMABLE ELECTRONIC THERMOSTAT
