A - Montage / Installation
• See the main characteristics in the Technical Instructions (for the "RCC").
• Consult the "Installation instructions" supplied with the control.
• Connection to the unit is made using at least 0.75 mm
of the printed circuit board located in the electrical box.
• The cables used must comply with the insulation requirements for the voltage used (230V).
This information relates above all to the sensor input of the automatic control connected to the 230V supply.
• The temperature adjustment range can be limited by means of the mechanical limit stops located on the control knob.
Wall mounting:
• Secure the unit at a height of approximately 1.5 m from the fl oor in a location representative of normal convection currents,
while avoiding:
- wall which are poorly insulated or liable to vibrate,
- the proximity of parasitic heat sources (sunshine, heating appliances, lamps, fi replaces, televisions, etc.),
- currents of air from doors or windows,
- sheltered locations such as shelves or behind curtains,
- near electrical outlets.
• For manual control 70250076, check and modify as required the ventilation selection jumper connection SR depending
on the appliance (see below).
• For automatic control (70250051 and 70250052), check and modify as required the settings on DIP switches 1 to 5
(located inside the control) depending on the application (refer to the indications below and the controller's technical
manuals).
B - Connections with manual remote control - code 7025076 ("RAB 30")
• For CWX "2-pipe", "2-pipe cooling + electric heating" and "4-pipe".
• Manual selection of the operating mode (heating or cooling).
• Control by action on the 230V "On/Off" valve.
• Permanent or slaved ventilation.
Position of the SR bridge located inside the controller:
- on SR1
- on SR2 (Auto) = Ventilation actuated with the valve.
