Parameter “Period of sending setpoint”
Options
：
5s
10s
…
2h
Parameter of “Send setpoint” is use for setting the interval of sending a temperature setpoint
recurrently from its sensor to bus. The interval setting can be found in choosing “cyclically” or “on change
and cyclically” in the Parameter of “Send setpoint”.
Parameter “switchover between heating and cooling”
Options
：
automate switchover by dead zone
manual switchover by object
This parameter is use for setting the switching ways of Heating/cooling function.
When choosing “automate switchover by dead zone”, it will switch to heating/cooling automatically
according to the dead zone. It will switch to the cooling system if the current temperature is warmer than
the temperature setpoint under cooling comfort mode. It will switch to the cooling system if the current
temperature is lower than the temperature setpoint under heating comfort mode. When Choosing
switching heating/cooling automatically in the parameter of “Switchover between heating and cooling”,
the object of “Heating/cooling switchover” will send the current status of heating/cooling to the fan coil
controller or any other corresponding controllers to warm/cool.
Under the condition of relative adjustment, we can know the temperature setpoint under the cooling
comfort mode by setting the parameter in different dead zone. Details are as follows.
Temperature setpoint of the cooling comfort mode = Temperature setpoint of the heating comfort
mode + dead zone.
If the values of dead zone is 3
℃
, temperature setpoint under the heating comfort mode is 22
℃
, that
means the temperature setpoint of the cooling comfort mode is 25
℃。
When choosing “manual switchover by object”, it means that we can switch the heating or cooling
manually by long press the mode key. The object “Heating/cooling switchover” will send the status to
the bus. “1”, means heating; “0”, means cooling.
Parameter “Automatic transmission heating/cooling switchover”
