4.6 Heating and cooling outputs
The behavior of the outputs (Free contact) is dependent of the DIP3 (See 3.3):
• DIP3 = OFF: The Heating or cooling output is triggered constantly following the mode
of the installation (heating or cooling).
• DIP3 = ON: The heating/cooling output is activated when there is a heating or a
cooling demand in the installation.
In case of RF failure, the heating output is triggered all the time.
4.7 External antenna
The distance between 2 devices with internal antenna should be at least 50 cm.
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 opti-
mize sensitivity and avoid any
dysfunction
Antenna must be installed:
• outside the metallic box
• in vertical position
• and at least at 50 cm of metallic parts
5. System configuration
The SH-HCM should be always paired to a SH-CD controller, even if you are using a SH-CU. There is always only one
SH-HCM per installation.
