E12 Enable Own Energy Consumptn For Heating Water Buffer Cyl - Viessmann VITOTRONIC 200 Service Instructions Manual

7E12 Enable own energy consumptn for heating water buffer cyl.

If heating of the buffer cylinder with power generated
on site is enabled, the set buffer temperature is
increased compared to operation with power from the
grid, by applying "Raise set heating water buffer cyl-
inder temp PV 7E22".
Note
If the electrical output of the photovoltaic system
becomes insufficient during buffer cylinder heating,
raising the set buffer temperature ceases to be effec-
tive. Charging continues with electricity from the mains
until the temperature in the buffer cylinder reaches the
currently applicable set value.
7E13 Enable own energy consumption for heating
If central heating with on-site power consumption is
enabled, the "Standard room temperature 2000" or
"Reduced room temperature 2001" increases com-
pared to operation with power from the mains by
"Raise set room temperature PV 7E23".
Note
"Raise set room temperature PV 7E23" will no lon-
ger be effective if the electrical output of the PV sys-
tem is no longer sufficient during central heating.
7E15 Enable own energy consumption for cooling
The set room temperature ("Standard room tempera-
ture 2000" or "Reduced room temperature 2001") is
reduced, compared to operation with power from the
grid by "Reduce set room temperature PV 7E25".
Note
Applicable for cooling via a heating/cooling circuit or
the separate cooling circuit.
7E16 Enable own energy consumptn for coolant buffer cylinder
If cooling of the heating water/coolant buffer cylinder
with power generated on site is enabled, the set buffer
temperature is reduced compared to operation with
power from the grid, by applying "Reduce set coolant
buffer cylinder temperature PV 7E26".
Note
If the electrical output of the photovoltaic system
becomes insufficient whilst the heating water/coolant
buffer cylinder is being cooled, "Reduce set coolant
buffer cylinder temperature PV 7E26" ceases to be
effective. Cooling continues with power from the grid
until the temperature in the heating water/coolant buf-
fer cylinder reaches the currently valid set value.
