To do this, the controller must be installed in the living area
and assigned to a zone. The thermostat function must be
activated.

Hybrid manager
–
You can use this function to determine the hybrid man-
ager with which the heating installation should be con-
trolled.
The hybrid heat pump always works with the
triVAI
function,
meaning that the
Hybrid manager
function appears as a list
point on the display.
triVAI
: The price-oriented hybrid manager picks the heat
generator on the basis of the rates set in relation to the
energy requirement.
Biv. point
: The bivalence point hybrid manager picks the
heat generator on the basis of the outside temperature.

Heat. bivalence point
–
If the bivalence point is selected for the
Hybrid manager
function, you can use the
Heat. bivalence point
function.
When outside temperatures are low, an auxiliary heater
helps the heat pump to generate the energy required. You
can use this function to set the outside temperature above
which the auxiliary heater remains switched off.

DHW bivalence point
–
When outside temperatures are low, an auxiliary heater
helps the heat pump to generate the energy required for
hot water generation. You can use this function to set the
outside temperature below which the auxiliary heater is
enabled.
Irrespective of the affected setting, the auxiliary heater for
the Anti-legionella function is activated.

Alternative point
–
If the bivalence point is selected for the
Hybrid manager
function, you can use the
Alternative point
function.
The function represents the alternative point. When the out-
side temperature lies below the set temperature value, the
controller always switches the heat pump off and the auxili-
ary heater creates the required energy in heating mode.

T. emergency mode
–
If a heat pump is connected, you can use the
T. emer-
gency mode
function.
If the heat pump fails, the auxiliary heater generates the re-
quired energy. To avoid high heating costs due to the auxili-
ary heater, set a low flow temperature.
The operator notices a heat loss and recognises that there
is a problem with the heat pump. In addition, the message
Restricted operation/ comfort protection
appears in the
display. If the operator releases the auxiliary heater to gen-
erate the required energy, the controller overrides the set
temperature for limp home mode.
You cannot use this function with the hybrid heat pump and it
therefore does not appear in the listbox.

Auxiliary heater type
–
If the
triVAI
entry is selected for the
Hybrid manager
function, you can use the
Auxiliary heater type
function.
This function allows you to select which heat generator,
apart from the heat pump, is still installed.
To ensure that the heat pump and additional heat generator
can work effectively and in coordination, you must select the
applicable heat generator. If the heat generator setting is
incorrect, this may lead to increased costs for the operator.

energy provider

Energy supplier
–
The energy provider can use this function to send a de-
activation signal.
The deactivation signal relates to the heat pump, the auxil-
iary heater and the system's heating and cooling functions.
You can specify which units and functions are deactivated
by the controller. The units and functions specified are de-
activated until the energy provider cancels the deactivation
signal.
The heat generator ignores the deactivation signal as soon
as the heat generator is in frost protection mode.

You can use this function to specify whether the auxiliary
heater should support the heat pump for hot water, heat-
ing or not at all.
–
DHW
: Supports the heat pump during hot water genera-
tion
The auxiliary heater is activated for frost protection or de-
icing the heat pump.
–
Heating

The auxiliary heater is activated for the Anti-legionella
function.
–
DHW+heat.
: Supports the heat pump during hot water
generation and heating
–
Inactive
: No support is provided to the heat pump
The auxiliary heater is activated for the Anti-legionella
function, frost protection or de-icing.
If the auxiliary heater is inactive, the system cannot guaran-
tee comfort.
You cannot use this function with the hybrid heat pump and it
therefore does not appear in the listbox.
