4.6 NC/NO actuators
Connect one NC or NO actuator per connector.
• 230V actuators for WFC-03 6Z HC RF 230 and WFC-03 10Z HC RF 230.
• 24V actuators for WFC-03 6Z HC RF 24 and WFC-03 10Z HC RF 24.
The type of actuators is defined by DIP2.
It is necessary to use the same type for all actuators.
When there is a heating or cooling demand in one zone, the actuator is triggered immediately.
When the heating or cooling demand is stopped, the actuator is closed immediately except if this is the last actuator opened in
the controller. In that case, the delay before starting to close the actuator is dependent of DIP3 (See 3.3).
• If DIP3 = OFF, the system waits 5mn before closing the last actuator.
• If DIP3 = ON, the system waits 20mn before closing the last actuator.
Justification:
Many heat pumps have a built in turn-off delay (to avoid successive switch OFF/ON). In this case, the heat pump continues to
run for x minutes beyond the actual switch-off time. It is important to keep at least one circuit open unless there is a buffer tank,
hydraulic switch or bypass in the installation.
4.7 External antenna
The controller embeds an internal antenna.
If require, an external antenna can be connected to improve the RF communication. It could be useful if
the controller is installed inside a metallic box. In that case, you need to install the external antenna outside
the metallic box.
Please respect the mounting to optimize
sensitivity and avoid any dysfunction.
Antenna must be installed:
• Outside the metallic box.
• In vertical position.
• And at least at 50cm of metallic parts.
If you have several antenna (several controllers),
they must be placed at minimum 80cm of each
other.
The active antenna must be mounted
vertically.
