Model 6303
6303
Control Panel
THE EASIEST HEAT PUMP CONTROL AVAILABLE
The Model 6303 control panel is designed for single-stage compressor,
heat pump systems only. A single-stage heat/cool (four wire) thermostat
can be used in each zone for the most economical installation solution;
however, a heat pump thermostat can be used in zone one for living space
control of the emergency heat mode. When heat/cool thermostats are used in all zones,
emergency heat is set at the control panel via a convenient switch. Auxiliary heat is controlled by a
fixed timer set for 20 minutes to assure homeowner comfort without expensive heat pump thermostats. The
simplicity and low cost of the Model 6303 make it perfect for new construction applications or existing homes.
