The room controller can be mounted on a wall or inside the fan coil unit. The mounting
location on a wall should not be in niches or bookshelves, not behind curtains, above or
near heat sources and not exposed to direct solar radiation. Mounting height is about
1.5 m above the floor.
The controller can be fitted on a recessed conduit box.
When using a heating / cooling changeover sensor, then, before fitting the sensor,
thermal conductive paste must be applied to the location on the pipe where the sensor
is placed.
Also refer to the Mounting Instructions B3057 enclosed with the controller.
• Wiring, protection and earthing must be installed in compliance with local
regulations. It must be made certain that safety extra low-voltage lines (SELV
circuit) are clearly separated from AC 230 V mains voltage cable
• The cables to the controller, external sensor, fan and valves carry AC 230 V mains
voltage and must be appropriate sized
• Only sensors and valves rated for AC 230 V may be used
• The AC 230 V mains supply line must have a circuit breaker with a rated current of
no more than C 10 A
Warning!
No internal line protection for supply lines to external consumers
(Q1, Q2, Q3, Y11, Y12)
Risk of fire and injury due to short-circuits!
• Adapt the line diameters as per local regulations to the rated value of the installed
overcurrent protection device.
• Maximum 10 changeover contact inputs B1-M can be connected in parallel if an
external switch is used in place of a changeover sensor. The switch must be suited
for AC 230 V. The cable length must not exceed 80 m overall
• Maximum 10 operating mode changeover contact inputs D1-GND can be connected
in parallel. The cable length must not exceed 80 m overall
