Control functions
Maximum and minimum limits for the output signal can be set, see section 2.2 .
Table 2-5 Controller output configuration values and controller output types.

Figure 2-6 illustrates the control behaviour in heating mode, and when no maximum or minimum limits are
set.
The heating demand increases as the room temperature falls. When the room temperature falls below the
heating setpoint,
Y1: Change-over (heating mode) signal increases to respond to the heating demand. At 100%
heating demand, Y1: Change-over (heating mode) signal reaches its maximum.
When the room temperature is higher than the heating setpoint and no heating demand exists, Y1: Change-
over (heating mode) signal is at its minimum.
Figure 2-6 Control behaviour for the Heating/Cooling (change-over) controller mode when the controller is in heating
mode.
Figure 2-7 illustrates the control behaviour in cooling mode, and when no maximum or minimum limits are
set.
The cooling demand increases as the room temperature rises. When the room temperature rises above the
cooling setpoint,
Y1: Change-over (cooling mode) signal increases to respond to the cooling demand. At 100%
cooling demand, Y1: Change-over (cooling mode) signal reaches its maximum.
When the room temperature is lower than the cooling setpoint and no cooling demand exists, Y1: Change-
over (cooling mode) signal is at its minimum.
