794 1094 1394 Heat up gradient
The heating up gradient represents the time in minutes the heating system requires to
raise the room temperature by 1 °C. This setting is used to calculate a fictive room
temperature for rooms without room sensor (Room temp 1 model (8742), Room temp 2
model (8772), and Room temp 3 model (8802)).
6.5.19 Raising the Reduced setpoint
This function is used primarily with heating systems that have only little spare capacity
(e.g. low-energy houses). In such cases, the heating up time would be too long at low
outside temperatures. When the Reduced setpoint is increased, the rooms are
prevented from cooling down to extremely low levels, thus shortening the heating up
time when changing to the Comfort setpoint.
