Carrier's 52SE Packaged Terminal Air Conditioner with Resistance Heat Units are available in nominal capacities 7,100 to 13,700 Btuh cooling and electric heat capacities from 6,400 to 17,000 Btuh. Resistance Heat is also known as 'heat strip' or ' electric strip' units. The 52SE and the 52SQ both cool in the same way. The compressor pulls in out door air, thereby removing heat energy from the air and expelling the heat as a byproduct out the back unit. The cool air is dispersed into the room. Where they differ is in the heating mode. Resistant heat units work by heating an electric heat element, similar to that of a toaster. The coil heats up quickly while a fan blows air across the coils, thereby dispensing warm air into the room. |

Carrier's 52SQ Packaged Terminal Heat Pump with Back-up Resistance Heat Units are available in nominal capacities from 6,900 to 13,500 Btuh cooling and heat pump capacities from 6,900 to 11,000 Btuh. Heat pump units are also known as 'reverse cycle heating'. The 52SE and 52 SQ both cool in the same way. The compressor pulls in out door air, thereby removing heat energy from the air and expelling the heat as a byproduct out the back unit. The cool air is dispersed into the room. Where they differ is in the heating mode. Upon start-up, the back-up resistance heat kicks on to heat the room quickly and bring the room temperature up to a set point. Once a set point is reached, the compressor then takes over, kicking on and off to help maintain the room temperature. If the room temperature falls 4 or more degrees Fahrenheit below set point, again the back up heat strip will come to push indoor temperature within 3 degrees below setpoint. There is another important feature about the heat pump that needs to be kept in mind. When the outdoor temperature drops below 35 degrees Fahrenheit, the heat pump automatically and the back-up resistance heat is utilized As the outdoor temperature drops, the heat pump cannot meet the heating demands, therefore the heat strip becomes more efficient in colder temperatures. The option to manually shut off the heat pump mode and go to the back-up heat strip has been made available. Simply remove the front cover and there is a manual switch or screw that will allow you to make the change. When seasons change from heating to cooling, however, the unit must be in heat pump mode to engage the compressor so that it maybe utilized in the cooling mode. |
