Lowest preheat time for OPT preheat P3 Units: Min, Default: 0, Range: 0 to 120
This is the minimum warm-up time for optimum start. This specifies a minimum
amount by which to advance the scheduled start time in heating mode
regardless of the actual optimum start calculation.
High speed pre-heat factor P4 Units: Min/F Deg, Default 18, Range: 0 to 100
Warm-up rate for optimum start. When the plant is turned on for heating, this
value is the number of minutes it takes to increase room temperature by 1
degree This value can be automatically adjusted if the adaptation option is
enabled.
Optimum stop OAT low limit
for opt. switch off P5 Units: Deg, Default: 10, Range: -15 to 24
Minimum outside air temperature for optimum stop. When outside air
temperature is at or below this value, the stop time will not be advanced in
heating mode.
Optimum stop factor P6 Units: Min/F Deg, Default 10, Range: 0 to 100
Optimum stop factor. For optimum stop during heating, this value sets the
amount of influence that the difference between room temperature and its
setpoint has on advancing or retarding the optimum stop calculation. The base
stop time is 120 minutes before the schedule stop time. For every degree that
the room temperature is below setpoint, the base stop time will be decreased by
the value of this parameter. For every degree that the room temperature is
above setpoint, the base setpoint will be increased by the value of this
parameter. Set to 0 to make optimum stop during heating solely dependent on
outside air temperature.
Cooling Case
Lowest cooling time for opt. cooling P7 Units: Min, Default: 0, Range: 0 to 120
Minimum cool-down time for optimum start. This specifies a minimum amount
by which to advance the schedule start time in cooling mode regardless of the
actual optimum start calculation.
