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
the printed circuit board located in the electrical box.
• The cables used must comply with the insulation requirements for the voltage used (230V).
This comment especially concerns the control probe inputs which are connected to 230 V.
• 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 floor 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, fireplaces, 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, check and possibly modify the settings of DIP switches 1 to 5 (located inside the control)
according to the application (refer to the indications below and the controller's technical manual).
B - Connections with manual remote control - code70250076 ("RAB 30")
• Manual selection of the operating mode (heating or cooling).
• Control by action on the 230V "On / Off" valve.
• Permanent or slaved ventilation.
C - Connections with automatic remote control - code 70250051 ("RCC 10")
• Automatic switching of the operating mode, by sensor or external contact.
Note: If the control is to operate only in
cooling mode, shunt terminals M and
B2 (otherwise the unit will remain in
heating mode).
• Control by action on the 230V
"On / Off" valve.
• Permanent or slaved ventilation.
• Mode change possible (Eco or Stand-
by) by external contact.
• For all technical
concerning the operation of this
controller, consult
Instructions No. 10 12 151.
