6.5.2 Compensation variants
The compensation variant (CV) determines the variable (outside temperature or room
temperature setpoint) according to which the flow temperature of the heating circuits
shall be controlled.
The compensation variant is generated automatically based on the existing
temperature values of outside temperature (OT), room temperature (TR),
parameterization of room thermostat setpoint and the room thermostat inputs.
Parameter Room influence (750/1050/1350) impacts the compensation behavior if
there is no room thermostat and if both temperature values are available.
The following compensation variants are available:
Weather compensation alone (WW)
Control is performed via the heating curve, based solely on the outside temperature.
Room temperature control (RR):
Control is performed based solely on the room temperature.
Weather compensation with room influence (WR):
Control is performed via the heating curve and the room temperature, based on the
outside temperature.
Room thermostat control with setpoint (RT-S)
Control is performed only when the room thermostat's state is Cold, using a fixed
setpoint.
Room thermostat control with weather compensation alone (RT-WW)
Control is performed only when the room thermostat's state is Cold, based on the
outside temperature and the heating curve.
Room thermostat control with room control (RT-RR)
Note!
Control is performed only when the room thermostat's state is Cold, based on the
room temperature. This setting may result from the use of a room thermostat in
connection with a room unit with built-in sensor, but does not make much sense from
a practical point of view.
Room thermostat control and weather compensation with room influence (RT-
WR)
Note!
Control is performed only when the room thermostat's state is Cold, based on the
outside temperature, the heating curve and the room temperature. This setting may
result from the use of a room thermostat in connection with a room unit with built-in
sensor, but does not make much sense from a practical point of view.
