Operating instructions
25
When the frost protection function is active, the Controller
RoCon HP standard display shows the
symbol alongside the
time.
If the inflow heating temperature drops below 7 °C, the Daikin
Altherma EHS(X/H) heats up until the temperature reaches at
least 12 °C once more.
The function ceases once the outside temperature has risen to
the set parameter value [T-Frost Protect] + 1 K is reached and
there are no other activation conditions present.
Off-peak tariff activated;
– parameter [HT/NT Function] = 3
or
– parameter [SMART GRID] = 1,
the heat pump operation can be completely switched
off by the energy supply company for a limited period of
time. In such cases, no additional heating is carried out
and the internal device heating circulation pump is not
switched on, even in frost-protection conditions.
These situations can arise when the "Overview" infor-
mation level (see section 3.4.1) in the operating data
field "Ext" displays the value "HT" or "SG1".
3.6.6 Interlink function
Caution!
Incorrect flow temperatures can result in
damage to the underfloor heating sys-
tem or the build-up of condensation on
cooling surfaces.
●
Limit infeed target temperatures to
suitable ranges.
●
Heat distribution areas with different
design temperatures should be
installed as hydraulically separate
heating circuits.
Heating circuits with limited infeed tar-
get temperatures should possibly be
installed as mixing circuits controlled
by mixer modules.
Setting of the parameter [Interlink fct] = On offers the possibility
of the Daikin Altherma EHS(X/H) integrating two different infeed
target temperatures into the control system.
This applies both to a weather-controlled controller and a con-
troller using a fixed inflow target temperature (see section 3.6.4).
A possible use for this might be the additional integration of
aFWXV(15/20)AVEB in a surface heating and cooling system.
Requirement: 2 switching contacts (e.g. room thermostats) need
to be connected to plug connection J16 on the Daikin
Altherma EHS(X/H).
– Parameter [Interlink fct] = Off: deactivated
– Parameter [Interlink fct] = On: Evaluation of
and cooling
switching contacts at plug connection J16 on the
RoCon BM1 circuit board.
Activation of cooling mode only possible by changing operat-
ing mode to "Cooling" (see section 3.4.2).
Setting for the parameter [Room thermostat] no longer evalu-
ated.
a) Open switching contacts: only frost protection active.
b) Operating modes "Heating" or "Automatic 1" /
"Automatic 2" active during switching cycles in day mode.
– Closed switching contact heating
= IL1:
The system operates according to the normal infeed tar-
get temperature according to the parameter settings in
"HC Configuration"
>
"Heating"
.
– Closed switching contact cooling
= IL2:
The system operates according to the increased inflow
target temperature (normal inflow target tempe
value of parameter [T-Flow CH adj]. Priority if both switch-
ing contacts are closed.
c) "Cooling" operating mode active.
– Closed switching contact heating
= IL1:
The system operates according to the normal infeed tar-
get temperature according to the parameter settings in
"HC Configuration"
>
"Cooling"
.
– Closed switching contact cooling
= IL2:
The system operates according to the reduced inflow tar-
get temperature (normal inflow target temperature - value
of parameter [T-Flow Cooling adj]. Priority if both switch-
ing contacts are closed.
More detailed explanations and possible setting values for this function can be seen
in chapter 6.2.1.
3.6.7 Additional alternative heat generator
The heat supplied by an alternative heat generator must be
added to the unpressurised storage tank water in the Daikin
Altherma EHS(X/H) hot water storage tank.
– In the case of the optional backup heater EKBUxx, this is
managed by the construction.
– In the case of using an external heat generator (e.g. gas or oil
boiler) this can be integrated hydraulically
a) unpressurised via connections (solar infeed and solar
return) of the hot water tank
or
b) in device types Daikin Altherma EHS(X/H)B, via the
integrated solar pressure heat exchanger.
Adjustment of the [Function Heating ] sets whether and which ad-
ditional heat generators (WEZ) are available for domestic hot
water generation and heating support.
– 0: No additional WEZ
– 1: Optional backup heater EKBUxx (connected via XBUH1
plug)
– 2: Alternative WEZ takes over the hot water generation and
heating support. To demand from the heat generator, relay
K3 on the RTX-EHS circuit board is switched on.
– 3: Alternative WEZ 1 (optional backup heater EKBUxx) takes
over hot water generation and alternative WEZ 2 takes over
heating support To demand by WEZ 1 and WEZ 2, relay K3
and relay K1 respectively on the RTX-EHS circuit board are
switched on!
The operation of additional heat generators are also influenced
by the setting of the parameter [Equilibrium Func.]
(see chapter 6.2.1) and the parameter [Equilibrium Temp]
(see chapter 6.2.2).
More detailed explanations and possible setting values for this function can be seen
in chapter 6.2.1.
