The measured value is stored as the start and end temperature set value. - Page 39 The settings for set value increase or equilibrium phase must be adjusted by a professional partner after consultation with the floor screed professional! In- correct settings can lead to damage to the floor screed. OCHSNER accepts no li- ability for this!

Page 47: Procedure By Blocking
16.6 BLOCKING In "BLOCKING" cases, the system changes to "emergency mode economy". The heat pump is switched off. The system is controlled at reduced temperatures (heating and warm water) and the additional heat generators (electro auxiliary, furnace) take over the heating (if installed). -
Page 48: Heat Meter
17 Heat meter The OTE control offers the possibility of recording the amount of heat the heat pump gives off. The recording takes place using the classic heat meter method. The temperature differential of the heat pump is continuously measured and the amount of heat calculated with the flow rate. - Page 49 Select the heat pump by turning the ad- HEAT PUMP Heating m ode justment knob and confirm by pressing MENU ENTER OCHSNER OTE the knob. > the temperature image for the auxiliary heater appears.
