● If current humidity setpoint is not suitable for room humidity, setpoint shift is
activated via humidity control strategy (P451).
In cooling mode, much difference between the outside temperature and indoor
temperature can create discomfort and waste of energy. The thermostat can track
the outside temperature from the bus and adjust the cooling setpoint to ensure that
the difference is not too high. If outside temperature is higher than 26 °C and 6 K
above Comfort cooling setpoint, comfort cooling setpoint is shifted and kept as 6 K
below outside temperature. This function can be enabled or disabled via P255.
The current setpoint (used by the thermostat for temperature control) is available
on the bus for use in the central control unit.
The Comfort setpoint w (for example, customer setting on the display) and the
current setpoint w2 (used by the thermostat for temperature control, but not on the
display) is handled differently depending on the selected application and setting.
