Start Optimisation For Dhw Heating - Viessmann VITOTRONIC 200 Service Instructions Manual

Parameter group DHW
6008 Hysteresis DHW temperature booster heater
Note
DHW reheating with electric heaters is only possible if
"Enable electric heaters for DHW heating 6015" is
set to "1".
Set a higher value for "Hysteresis DHW temperature
booster heater 6008" than for "Hysteresis DHW
temperature heat pump 6007". Otherwise the propor-
tion of DHW reheating provided by the booster heaters
will increase.

6009 Start optimisation for DHW heating

Comfort function for heating the DHW cylinder.
The set cylinder temperature has already been
reached at the start of a time phase in the time pro-
gram for DHW heating.
Note
The start time for DHW heating results from "Temper-
ature rise per hour for DHW heating 600D".
600A Stop optimisation for DHW heating
Comfort function for heating the DHW cylinder.
The set cylinder temperature is always reached at the
end of a time phase in the DHW heating time program.
Note
The start time for DHW heating results from "Temper-
ature rise per hour for DHW heating 600D".
600C Set DHW temperature 2
Set cylinder temperature for the following functions:
■ DHW heating according to time program with operat-
ing status "Temp. 2"
■ DHW heating outside the time program: "1x DHW
heating" or "Manual mode"
600D Temperature rise per hour for DHW heating
Temperature rise for starting booster heaters
If the temperature rise during DHW heating with the
heat pump remains below the set value, the control
unit starts the immersion heater, instantaneous heating
water heater or external heat generator.
Temperature rise for start and stop optimisation
This parameter specifies the temperature rise for cal-
culating the heat-up time. The relevant start time for
DHW heating results from the heat-up duration.

Standard setting value
As a guideline for this setting, it can be assumed that
1 kW of heat pump output raises the temperature of
100 l water by approx. 10 K/h.
Example:
A heat pump with an output of 6 kW therefore raises
the temperature of a cylinder volume of 200 l by
approx. 30 K/h.
