On/Off
On/Off controller operate as a simple switch around the given setpoint using hysteresis values. Hysteresis
values prevent the thermostat from oscillation and give larger margin to turning heat or cool on or off. When
system is more active hysteresis values should be given larger and more inactive values can be given smaller.
4.4.3.4
Fan coil
Fan coil uses the same control type and same output type as “PI Continuous”, only difference fan coil enables
“Fan Control” parameters and communication objects.
4.4.3.5
Split
Split controller does not directly control the split AC, So ambient temperature must be controller by split AC’s
controller. Therefore, “Ambient Temperature” and “Setpoint Temperature” of split ACs communication objects
should be linked to “Current Temperature” and “Current Setpoint” communication objects. Otherwise, split
unit will be unaware of setpoint and ambient temperature and temperature control will not function correctly.
“Split Heat” and “Split Cool” communication objects are given to only to notify the split AC when there is a
control mode change (heat - cool). Also, when both heating controller and cooling controller configured as
“Split Unit” only one “Split Heat/Cool” communication object will be revealed regardless of “Control Output
Type” parameter in “Thermostat Parameters” tab.
