Adapting The Day Curve; Temperature Limitation - Fronius Ohmpilot Bedienungsanleitung

Adapting the Day This function ensures that a required temperature is not undercut. If there is not sufficient
Curve surplus power available, the external source will be started up, if activated, or otherwise
electricity will be drawn from the grid in order to ensure a minimum temperature.
Up to four time periods can be defined so that, for example, higher hot water temper-
atures are only certain to be available at night, but more potential is possible for the
surplus during the day due to the fact that a lower target temperature is selected.
1. Highlight the field "Temperature sensor present"
2. Highlight the field "Adapt day curve"
3. Under "Time from", enter the time from which the Ohmpilot should start to heat to the
new target temperature. This target temperature is valid until the next entry.
4. Under "Target temperature", enter the required final temperature.
Example:
05:00 10°C=> After showers, the hot water will only be produced with surplus energy
16:00 45°C=> If there was not sufficient excess energy, the water will be heated
18:00 10°C=> After showers, no more heating should occur, thus minimizing heating
03:00 45°C=> Water will be warmed so that it is ready for showers at 6am
Temperature If heater 1 does not have a configurable thermostat, this function can be used to limit the
Limitation temperature.
1. Highlight the field "Temperature sensor present"
2. Highlight the field "Temperature limitation"
3. Enter the maximum temperature (e.g. 60 °C).

WARNING! No guaranteed legionella prevention.
NOTE! One entry is valid for the whole day.
NOTE! If heater 1 is the primary heat source, the day curve must in all cases be
adapted to ensure the required minimum temperature. A PT1000 temperature
sensor is required for this function and can be sourced from Fronius under item
number 43,0001,1188. The position of the temperature sensor in the boiler
should be chosen so that sufficient hot water is available. However, it must in all
cases be installed above the heating element/external source.

NOTE! This function is only possible for heater 1. If a second heating element is
in use as heater 2, this must have a thermostat. A PT1000 temperature sensor
is required for this function and can be sourced from Fronius under item number
43,0001,1188. The temperature sensor should be installed just above the
heating element, so that the cold water flowing in is immediately heated up
again and the maximum storage amount is therefore used.
