3.1.4.10 Connection example for floating valve
A floating valve has three connections:
one for opening the valve (
W
for heating valve and
Y
for cooling valve)
one for closing the valve (
RV output
)
one for ground; COM (neutral)
One of the three connections is always fully closed. While one of the valves is activated,
the valves open slowly during the desired time, and while deactivating the valves close slowly
for the desired time.
Example:
Figure 23
When the thermostat is in
heating mode
, the
W output
is used for increasing the temperature
and the
RV output
is used for decreasing the temperature.
When the thermostat is in
cooling mode
, the
Y output
is used for decreasing the temperature
and the
RV output
is used for increasing the temperature.
To control the floating valves, the below parameters must be configured in Visionline.
Note:
Heating and cooling must be configured separately, under
HVAC/Heating
and
HVAC/
Cooling
respectively in Visionline. For information about the settings that can be made for
floating valves, click here.
