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 a
heating/cooling equipment, and not exposed to drip or splash water
See the Mounting Instructions M1429 enclosed with the thermostat.
• Ensure that wiring, fusing 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
• The AC 230 V mains supply line must have an external fuse or 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 reset was made correctly. After the reset, the ther-
mostat is ready for commissioning by qualified HVAC personnel.
The control parameters of the thermostat can be set to ensure optimum perform-
ance of the entire system. Please refer to Operating Instructions CB1B1421, sec-
tion "Do you want to change parameters?".
If the temperature on the display does not agree with the room temperature effec-
tively 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.
Since the thermostat uses touch technology and to minimize battery power con-
sumption, a parameter P21 (adjustable from 0.25 to 1.5 seconds) is implemented
for the user to adjust. This function is only valid for the battery-powered version
and the default value is 1 second.
This means that when, for a certain time, the user does not touch the touchpad, the
unit operates in power saving mode and the touchpad is running at a scanning rate
of 1 second.
