The diagram illustrates the valve drive sequence in  
a 4-pipe system with neutral zone. In the diagram  
it is assumed that the outputs are configured for  
proportionaldirectaction(0..10V),whileanyeffects  
ofthesupplementarytimearedisregarded.Similarly,  
in the case of a 2-pipe system, the valve output  
(heating valve output) would be driven at the same  
way. In this case Ts (set-point temperature) would  
coincide with Ts ris in winter, and Ts raf in summer.

The diagram illustrates the valve drive sequence  
in a 4-pipe system with neutral zone. Similarly, the  
heating valve output (HEAT) in a 2-pipe system  
would be driven in the same way. In this case, Ts  
(set-point temperature) would coincide with Ts ris  
in winter and Ts raf in summer.

This diagram disregards the effects of the supplementary time, if any, and assumes that the fan  
proportional output (V FAN) is configured for direct action (P05=0) and a 0..10V signal (C15=0; C16  
=100). The fan proportional output is always turned off (0V) when the COOL or HEAT valve output,  
is off (not shown on the diagram).
