STEP 4 SETTING THE SYSTEM AND FAN SWITCHES ON THE SUBBASE The T8631A does not have the EM. HT. switch position. Note the positions provided on your subbase, then set the switch(s) as desired. First set the fan switch.
FAN ON: Use for improved air circulation during special occasions or for more efficient electronic air cleaning. The fan runs continuously. FAN AUTO: Normal setting for most homes and businesses. T8631A: the fan starts and stops with the air conditioner and with the heating equipment when the fan switch (4A) is set for electric heat. When 4A is set for conventional heat, the fan is controlled by the heating equipment. T8631R: the fan starts and stops with the compressor in heat pump systems when the system switch is set to HEAT or COOL. When system switch is set to EM. HT., the fan operates with the auxiliary heat (on some models). EM. HT. (T8631R only): The thermostat controls only the backup heat. The heat pump is off.
