A - Assembly / Installation
• See the main characteristics in the Technical Instructions corresponding to the TWN (No. 10 12 172).
• Consult the "Installation instructions" supplied with the control.
• The unit is connected using 0.75mm
2 cable (minimum) (1.5mm 2 max.).
The cables used must comply with the insulation requirements for the voltage used (230 V). This information relates
above all to the sensor input of the automatic control connected to the 230 V supply.
• The temperature adjustment range can be limited using the mechanical limit stops located on the control knob of RAB
and RCC control units.
• 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 the K70P090Z and K70P091Z control, refer to the corresponding technical instructions.
• For manual control 70250076 , check and modify as required the ventilation selection jumper connection SR depending
on the appliance (see below).
• For " RCC " type controls ( 70250051 and 70250052 ), check and modify as required the settings on DIP switches 1 to 8
(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 RAB 30 - code 70250076
• For "2-pipe" or "4-pipe" (or “2-pipe” C electric heater element) TWN .
• Manual selection of the operating mode (heating or cooling).
• Control by action on the 230 V "On/Off" valve and/or on ventilation.
