The curve can be set either as simple, or as split that is divided by a slope change point into two parts. The simple curve can be set using one parameter.
- Page 24 In this manner it is possible to carry out e.g. quick heating up after night operating hours through a steeper heating water temperature rise, or on the contrary, a quicker temperature drop during a faster transition to night operating hours. 5.1.9.
- Page 25 5.1.17. Thermal inertia of a building Thermal inertia of a building indicates how fast the calculated desired heating water temperature (following the heating curve) is influenced by a change in outdoor temperature. The heavier the building design, the more slowly can be the heating water temperature modified through the outdoor temperature.

Page 46: Replacing The Fuse
Z.2 Replacing the Fuse Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power supply and secure it against being switched on again! Check for the absence of power! Only use the supplied spare fuse or a fuse of the same design with the following specifications: T2A 250V If the mains voltage is switched on and the controller still does not function or display anything, then the internal device fuse may be defective. - Page 48 ©2019 We reserve the right to errors, changes and improvements without prior notice.
