The WTC-3 can regulate mixing valves to set and keep
under control the inlet water temperature for heating and
cooling.
The built in program can keep the requested temperature
within +/- 0.3
°C.
The WTC-3 uses the PI regulation to keep an accurate
temperature. The PI regulation decreases over control and
stopped the wave effect within the shortest time.
Note
Any type of mixing valve controlled by 0-10V can be used.
The default inlet temperature values for heating:
45
°C
The default inlet temperature values for cooling:
16
°C
Both values can be modified in the software according to
request.
The Wavin temperature sensor must be placing after the
mixing valve and attached directly to the pipe!

n case of overheating ( 60
°C
). the pump will stop to work
a
nd consequently this will cause a mixing valve failure.

WTC-3 can control the inlet cooling water temperature
according to relative humidity.
