The WTC-3 is equipped to control motorized zone valves
to changeover from heating to cooling mode and vice
versa. This function is used with a four-pipe system.
In a four-pipe system, each inlet and outlet requires a two
p
ort motorised valve because of hydraulic reason
(balancing). All motorised valves are controlled by the
WTC-3.
The base unit has a default program function to prevent
unwanted temperature increase in the return flow pipe
system. During the changeover between heating and coo-
ling mode the WTC-3 closes the inlet and outlet motorized
valves, then waits ten minutes before opening the other
inlet and outlet motorized valves. This ten minute
presetting can be modify via the WTC-3 software
(1 — 16min).
