Run-on behavior speed 1:
After normal operation with running heat exchanger an immediate switch off (valve closed, fan off) can result in overheating in the unit.
For a fan coil in cooling mode it is essential to keep the fan running to prevent icing or condensation. Run-on times speed 3 and speed 2 to be adjusted to zero or low durations, Run-on time speed 1 will get a significant time period.

Webinar “Application FCU – Advanced Features”Limitations and forced operation
During operation (direct or automatic) it is sometime essential to influence both the valve and also the fan. It means, valve and/or fan achieve a defined status.
Examples:
In a hotel room ventilation shall be limited to speed one during the night due to noise reasons
In case of malfunction in a HVAC system valve shall go to 50 % position
For continuous ventilation with no heating or cooling valve shall be closed and fan runs in speed one

The Master is to be connected according to the designated communication objects with the slave. The Master is responsible for the temperature control.
Slave device(s) At least two RTCs in use. One defined as Master and the second as Slave. The Slave is to be connected according to the designated communication objects with the Master. The Slave uses the room temperature controller functions of the master

Important parameter:
The setpoint temperature of the additional stage is defined as the difference to the basic setpoint
The value represents the setpoint at which the additional stage starts to operate.
For heating the setpoint for the additional stage is higher, for cooling it is lower than the basic setpoint
Adjustment of the difference to zero:
Two parallel circuits with the same setpointbut different control parameters if required.

Switching between heating and cooling, either with 2-pipe or 4-pipe systems is important is to run in the correct mode, depending on request (required room temperature compared with actual one)
Option RTC:
Automatic: Device switches automatically between heating and cooling and to the associated setpoint
Only via object: Switchover between heating and cooling and to the associated setpoint is carried out via group object.
Local/ via extension unit and via object:Switchover between heating and cooling is carried out manually on the device by the user or via the "Switchover heating/cooling" object via the bus.

Practice:
2-pipe system with only heating or cooling: no adjustments in RTC or FCA/S
4-pipe system with both heating and cooling: mostly the automatic mode (RTC) and no switching object (FCA/S) can be parametrized. Depending on setpoint and current room temperature the right control value will be transmitted. FCA/S receives only one control value and operates the valve.
In case of the necessity to force running mode heating or cooling at a certain time (e.g. via visualization) these group objects and parameters in both devices are really helpful).

Practice:
In a 2-pipe system with both heating and cooling the switching object can be used to inform the RTC and FCA/S that hot or cold water is in the system and heating or cooling mode is active now. FCA/S parameter Fan coil operating mode has to be adjusted to ‘2 control values/1 valve/with switching object’. Both group objects shown above are connected with the same group address.
In a four pipe system with both heating and cooling but never hot and cold water supply in parallel intended switching between heating and cooling can be necessary

Webinar “Application FCU – Advanced Features”RTC in Presence Detector
Presence Detector includes a complete RTC except operating elements or indications
RTC in general areas like restroom or kitchen where no operation and display is needed
In a large office room it is recommended to measure at two points to create amean value or to regulate accordingto the lowest/highest measured room temperature
In principle both measured value can be weighted to create an individual reference temperature value. (E.g. RTC1 30 % and RTC2 70 %)

Webinar “Application FCU – Advanced Features”RTC in Presence Detector
For a ceiling mounted fan coil unit it is a good solution to measure the room temperature next to the air inlet of the FCU
Advantage is a faster regulation thus also the presence detector can help with temperature measurement
Please note: Air draft with temperaturedifferences can results in triggeringpresence detection when the detector is mounted next to the FCU
As the detection of temperature at the ceiling might be incorrect(in heating mode too high) an offset can be parametrized

Webinar “Application FCU – Advanced Features”Fan Coil Control with Blower Actuator FCL/S x.6.1.1
Room temperature control with fan coil units means fan speed and valve control.
Possible: Room temperature control only via fan speed, any cooling or heating request leads to a completely open valve
Simple relay for controlling of electrothermal valves is sufficient, Blower actuator FCL/S x.6.1.1.
Hint: For PWM control or continouscontrol the dedicated actuator FCA/S is needed !
