The setpoint for frost protection is the temperature that may not be
undershot during the frost protection mode. If the current temperature
undershoots the configured value, the ambient temperature controller
triggers a control value telegram that causes the relevant heating actuator
to heat up the room to prevent damage to the heating system from frost-
related cooling.
This parameter is only available if the "Heating" or "Heat and cool" control
functions are used.
