Parameter 46 pre-heating time at 0°C
By setting the quick heat-up time at an outside temperature of
0°C, the heat-up speed affected. This value is included in the
calculation of the pre-heating time.
Pre-heating time = pre-heating time 0°C/20°C x (room setpoint –
outside temperature)
Parameter 47 lowering ramp
This parameter setting specifies how fast the temperature is
reduced before the end point of the heating cycle is reached, e.g.
10 p.m.
