  Examples of installations 

12.2.1.2

Floor heating 1 + Floor heating 2 

 

 

 

Connect floor heating to 2 circuits through buffer tank as shown in the figure. 
Install mixing valves, pumps and thermistors (specified by Panasonic) on both circuits. 
Install the remote controller in one of the circuit and use it as Room Thermostat. 
Install external Room Thermostat (field supply) in another circuit. 
Both circuits can set circulation water temperature independently. 
Install buffer tank thermistor on buffer tank. 
It requires connection setting of buffer tank and 

∆

T temperature setting at heating operation separately. 

This system requires optional PCB (CZ-NS4P). 
 

Floor h Radiator 

 

 

 

Connect floor heating or radiator to 2 circuits through buffer tank as shown in figure. 
Install pumps and thermistors (specified by Panasonic) on both circuits. 
Install mixing valve in the circuit with lower temperature among the 2 circuits. 
(Generally, if install floor heating and radiator circuit at 2 zones, install mixing valve in floor heating circuit.) 
For temperature setting, select circulation water temperature for both circuits. 
Both circuits can set circulation water temperature independently. 
Install buffer tank thermistor on buffer tank. 
It requires connection setting of buffer tank and 

∆

T temperature setting at heating operation separately. 

This system requires the optional PCB (CZ-NS4P). 
Mind that if there is no mixing valve at the secondary side, the circulation water temperature may get higher than 
setting temperature.
