CZ-4K 

Master Zone Control Panel - up to 4  Zones  and use with single stage, multi-stage and heat  

 

 

pumps applications - includes leaving air sensor (CLAS) and transformer (use CAZ-2 for    

 

 

additional zones) 

 

CZ-4 

Master Zone Control Panel Controls up to 4 Thermostats and SPST or SPDT Zone Dampers

 

CAZ-2

CMM-3K 

2 and 3 Zone Single Stage Zone Panel, includes 24V transformer and CLAS

  CMM-3U 

2 Heat / 1 Cool Heat Pump and Multi-Stage, 1 Heat / 1 Cool Single Stage

 

CMM-3UK  2 Heat / 1 Cool Heat Pump and Multi-Stage, 1 Heat / 1 Cool Single Stage, includes 24V trans- 

 

 

former and CLAS

 

CMM-3 

2 and 3 Zone Single Stage Zoning Panel

 

CLAS 

Leaving Air Sensor for CZ-4

 

COAS 

Optional Outdoor Air Sensor for CMM-3U and CMM-3UK. Measures outdoor temperature and  

 

 

switches the heat from heat pump to fossil fuel furnace when the outdoor temperature falls  

 

 

below the balance point.

 

CAFC 

The CAFC prevents the air conditioning coil from freezing due to low air flow, dirty filters, low

 

 

refrigerant pressure, etc. The CAFC snaps onto the suction line close to the evaporator coil as  

possible and breaks the compressor circuit when the suction line drops below 36

o

F and re- 

make the circuit at 46

o

F. Recommended when by-passing air into the return duct.
