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).
