R/W
Communication address (must be unique in network)(factory default is "1")
R/W
Baud rate:
0 = 19200
1 = 4800
2 = 9600
3 = 19200
4 = 38400
R/W
Parity mode: 0 = No Parity, 1 =Even Parity, 2 = Odd Parity
R/W
Mode of communication : 0 = RTU, 1 = ASCII
R/W
Allow changing of communication address through broad cast command. (will
reset automatically after 30 seconds)
0 = Not allowed, 1 = Allowed
R/W
Total number of groups
0 = one group with fan speed selection on right key
1 = one group
2 = two groups
3 = three groups
4 = four groups
5 = five groups
R/W
Setpoint change enable
0 = disabled, 1 = enabled
R/W
Operation mode change ON/OFF enabled
0 = disabled, 1 = enabled
R/W
Operation mode change occupied / unoccupied enabled
0 = disabled, 1 = enabled
R/W
Clock with hours and minutes in BCD format
R/W
24h / 12h Clock mode: 0 = 24h, 1 = 12h (AM/PM)
R/W
AM/PM flag: 0 = AM, 1 = PM
R/W
Celsius/Fahrenheit: 0 = Celsius, 1 = Fahrenheit
R/W
Timeout in seconds to idle mode. (0...255 seconds)
R/W Idle mode, 0 = disabled, 1 = enabled
If enabled shows a specific screen if no key is pressed for the time defined in 1016
R/W Maximum number of FAN speeds (1...3)
This setting applies if number of groups is set to "one group with fan speed".
(1008 = 0).
R/W Humidity sensor calibration
R/W Internal NTC sensor calibration
R/W External NTC sensor calibration
R/W Modbus communication timeout: If there is no communication within the amount
of seconds specified here, "Err1" is shown on the small digits. Setting the value to
"0" disables this feature.
R/W Delay for remote disable function. The delay defines how long the contact needs to
be open before the device switches into OFF mode. This is used for key card
switches or window contacts connected to digital inputs. This function is controlled
with registers 10300/10400.
R/W Delay for standby/comfort switchover function. The delay defines how long the
contact needs to be open before the device switches into standby mode. This is
used for key card switches or motion detectors connected to digital inputs. This
function is controlled with registers 10300/10400.
