Regardless of size or shape, each thermostat will feature a temperature indicator; a dial, arm, or push button for selection of the desired temperature; a fan switch to choose the indoor fan operation; and a comfort switch for you to select the system mode of operation. COOLING ONLY If your air conditioning system is designed to provide cooling only (AC), with no capability for heating operation (electric heat), a single-stage cooling only thermostat, with a manual, one-position “Cool” and “Off” comfort switch is all that is required for system operation. NOTE: If you have an independent heating system (with a separate thermostat), always be sure the heating control is turned “Off” before turning on the cooling system. COOLING AND HEATING If your system has been designed to allow both cooling and heating operation, you may have either a manual change-over type, or a programmable electronic type thermostat. MANUAL CHANGE-OVER Manual change-over simply means that the comfort switch must be manually positioned every time you wish to switch from the cooling to heating or heating to cooling modes of operation. 131001-YUM-A-1205 131001-YUM-A-1205 SECTION III: PROGRAMMABLE ELECTRONIC THERMOSTATS The computerized electronic thermostat is actually a sophisticated electronic version of a manual change-over type. This thermostat includes features which allow “set-back” temperature variations for periods of sleep, or while you are away during the day, and means energy savings for you. The thermostat also features a digital clock. FIGURE 1: PROGRAMMABLE ELECTRONIC THERMOSTAT FIGURE 2: PROGRAMMABLE ELECTRONIC THERMOSTAT FAN OPERATION SELECTION A multi-position fan switch allows you to choose the type of fan operation of the indoor fan. AUTO With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cooling. This position will provide the lowest operating cost. If you purchased one of our thermostats, they have an Intelligent fan mode which continually circulates the air during occupied modes or when you are at home, and can cycle the fan during unoccupied mode or during the night while you sleep to further conserve energy. ON CONTINUOUS FAN OPERATION: With the thermostat fan switch set to “ON”, the indoor fan will not shut off. However, the cooling (AC) or heating (electric heat) systems will still operate as required by room temperatures. This provides continuous air filtering and more even temperature distribution to all conditioned spaces. FAN ONLY OPERATION: On moderate days, usually during spring and fall, when neither heating nor cooling is required, you may want to run only the fan to ventilate, circulate and filter the air in your home or building. 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 operation. SECTION IV: START-UP The comfort control switch is assumed to be in the “OFF” position. If the main power supply to the unit is off, turn the appropriate disconnects to the “ON” position. Place the system into operation as follows: 1. Set temperature adjustment to the desired temperature on your thermostat. 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 consumed. Federal guidelines recommend a setting of 65 °F or lower. NOTE: If your cooling and heating temperature adjustments are separate, be sure to set both. 2. After considering “Fan Operation Selection” above, select and set the 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 FAILURE When accidents, wind storms, etc. disrupt electrical power supply to your house, switch thermostat to “OFF” position. SECTION V: SYSTEM OPERATION MANUAL CHANGE-OVER THERMOSTAT COOLING YOUR HOME: With the comfort control switch in the “COOL” position, the system will operate as follows: When the indoor temperature rises above the level indicated by the temperature adjustment setting, the system will start. The unit will operate and the fan will circulate the cooled, filtered air. When the room temperature is lowered to the setting selected, the system will shut off. HEATING YOUR HOME: If your system includes a electric heat section and the comfort control switch is in the “HEAT...
