Heating Curve; Cooling - Daikin RoCon+ HP Betriebsanleitung

Heating curve

WARNING: FLAMMABLE MATERIAL
In the event of malfunction, the floor heating system, the
screed or the floor structure could be damaged due to
overheating.
▪ Prior to initial commissioning, set the maximum temper-
ature limit in the RoCon+ HP control unit ([Max. feed
temperature] parameter) to the maximum permitted sys-
tem temperature prior to starting the emission measure-
ment.
▪ Connect an overheating protection switch (in the build-
ing) at the "Ext" plug connection for external operating
mode switch-over so that the Daikin Altherma EHS(X/H)
is switched to the "Standby" or "Summer" operating
mode. If the [Room thermostat] parameter = Yesor the
[Interlink function] parameter = On, the overheating pro-
tection switch must be connected so that the room ther-
mostat's switching contact is interrupted.
▪ If the floor heating is also used for room cooling, the
connection notes in the above point also apply to the
connection of a moisture protection switch in the build-
ing.
The heating curve is used to adapt the feed temperature to the char-
acteristics of the building independent of the respective outside tem-
perature (weather-compensated feed temperature control, see
Chap. 4.5). Generally speaking, the steepness of the heating curve
describes the ratio of the feed temperature change to the external
temperature change.
The heating curve is valid within the limits of the minimum and max-
imum temperatures set for the respective HC. The room temperature
measured in the occupied area may differ from the required room
temperature; these deviations can be kept to a minimum by installing
a room thermostat or a room control.
The control unit is set at the factory in such a way that the heating
curve does not independently adjust itself during operation.
The automatic heating curve adjustment can be activated ([Heat-
ing curve adaptation] parameter) if the outside temperature sensor
and the room controller (EHS157034) are connected (see
4.5).
Start conditions for automatic heat slope adjustment:
▪ Outside temperature < 8 °C
▪ Operating mode is [Automatic 1 or Automatic 2]
▪ Duration of the setback period is at least 6 h
If no automatic heating curve adjustment is activated, the heating
curve can be manually adjusted by adjusting the [Heat-Slope]
parameter).
INFORMATION: MANUALLY ADJUSTING THE HEAT-
ING CURVE
Do not make any corrections to the set values for 1 - 2
days, and then only make them in small increments.
▪ Deactivate the external heat sources (e.g. stoves, direct
sunlight, open windows).
▪ Fully open any radiator thermostat valves or actuators.
▪ Activate "Heating" operating mode. Approximate setting
values:
Radiators and System 70: 1.4 to 1.6.
Floor heating: 0.5 to 0.9.

Comfort heating
If the heat pump cannot cover the heating demand when outside
temperatures are very low, heat is extracted from the storage tank
and used for room heating. In rare cases (in systems with high re-
quired feed temperatures and low required hot water temperatures),
the required feed temperature can be higher than the storage tank
target temperature. In order to avoid short-term loss of comfort in
heating mode for these systems, the [Comfort heating] parameter
can be set to "On". At corresponding outside temperatures, the stor-
Chap.
age tank temperature is raised above the storage tank temperature
set for the hot water requirement.
INFORMATION
If [Comfort heating] is set to "On", the power consumption
of the heat pump may increase. In the default setting,
[Comfort heating] is set to "Off".
Detailed explanations and possible setting values of this function can
be found in Chap.

Cooling

[→ Main menu → Configuration → Cooling]
This menu is used to make settings for cooling mode.
CAUTION: DANGER OF CONDENSATION
In the event of malfunction or incorrect parameter settings,
the floor heating, the screed or the floor structure could be
damaged due to condensation.
▪ Before initial commissioning and activation of cooling op-
eration, set the minimum temperature limit in the RoCon
controller ([Feed temperature lower limit] parameter) to
the minimum permissible system temperature.
Prerequisites for cooling mode:
▪ Outside temperature > set value of room target temperature
▪ Outside temperature > set value of the [Start T-Out Cooling] para-
meter
