Do not mount the thermostat in niches or bookshelves, not behind curtains, not
above or near heat sources, and not exposed to direct solar radiation. Mount about
1.5 m above the floor.
· Mount the thermostat in a clean and dry location without direct air flow from
heating/cooling equipment, and not exposed to drip or splash water
Note: When RDD100.. is equipped with either China 86 conduit box or BS4662 UK
conduit box, ARG70.4 adapter plate is suggested to provide a better fitting
installation.
See Mounting Instructions M1420 enclosed with the thermostat.
· Ensure that wiring, protection and earthing comply with local regulations
· Correctly size the cables to the thermostat and the valve actuators
· Use only valve actuators rated for AC 24...230 V
Warning!
No internal line protection for supply lines to external consumers.
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.
· The AC 230 V mains supply line must have a circuit breaker with a rated current
of no more than 10 A
· Disconnect from power supply before removing the unit from its mounting plate
After power is applied, the thermostat carries out a reset during which all LCD
segments flash, indicating that the reset was made correctly. After the reset, the
thermostat is ready for commissioning by qualified HVAC personnel.
The control parameters of the thermostat can be set to ensure optimum
performance of the entire system. Please refer to Operating Instructions
CB1B1420, section "Do you want to change parameters?".
If the temperature on the display does not agree with the room temperature
effectively measured, the temperature sensor can be recalibrated. For that
purpose, adjust parameter P04.
We recommend to review the setpoint range and setpoint lock (for public areas)
using parameters P05...P08 and change them as needed to achieve maximum
comfort and energy savings.
