Control value larger when sending change
Options: - 0%
- 1 %
- ...
- 5 %
- ...
- 15 %
The parameter "Control value larger when sending change" can be used to
influence the bus load. This setting is configured in percentages. The higher
the selected value, the fewer the control value telegrams sent by the room
thermostat. However, the value should not be set too high to ensure the
control works properly. A value of 5% will generally provide good control
results.
This parameter is only available if the "Heating" or "Heat and cool" control
functions are set and the "Heating" control type is set to "Continuous" or
"FanCoil".
Control parameter
Options: - Acc. to installation type
- free parameterization
This parameter allows you to configure the control based on the type
of system in use. The "Acc. to installation type" setting displays predefined
values for the different system types that most frequently provide good
control results. The setting "free parameterization" can be used to
individually update the proportional range and readjust time. Proper
knowledge in the field of control technology is required to use " free
parameterization ".
This parameter is only available if the "Heating" or "Heat and cool" control
functions are set and the heating control type is set to "PWM", "Continuous"
or "FanCoil".
Type of heating system
Options: - Warm water heating (1.5 K / 100 min)
- Electric heating (1.5 K/50 min)
- Floor heating (4 K/200 min)
- Split unit (4 K / 90 min)
The "Type of heating system" parameter enables you to select the heating
system in use with predefined control parameters.
This parameter is only available if the "Heating" or "Heat and cool" control
functions are set, the heating control type is set to "PWM", "Continuous" or
"FanCoil" and the control parameter is set to "via system type".
