4.1.5 Activating the Parameter [Air Purge]
By activating the Air Purge the RoCon HP control unit starts a de-
fined sequence program with Start-Stop
operation of the inte-
grated heat circulation pump and various settings for the 3-way
diverter valve integrated into the Daikin Altherma EHS(X/H).
Existing air can leak from the automatic venting valve during the
venting function and the hydraulic circuit connected to the Daikin
Altherma EHS(X/H) is evacuated.
Perform Air Purge (see operating manual of the control unit).
The activation of this function does not replace the cor-
rect venting of the heating circuit.
Prior to activating this function, the heating circuit must
be completely filled.
4.1.6 Check minimum flow
The minimum flow must be checked with a closed heating
circuit.
If the minimum flow is too low, an error message may
appear and the heating system may shut down.
If the minimum flow is insufficient:
there may be air in the circulation pump.
Vent the circulation pump.
the valve drive of the 3-way diverter valve (3UVB1 /
3
UV DHW) is defective.
Check the function of the valve drive, if neces-
sary, replace valve drive.
Close valves and actuators of all closed heat distribution
circuits.
Set "Hea
ting" operating mode on the control unit of the Daikin
Altherma EHS(X/H).
Read info parameter [Flow Rate].
The flow rate must be at least 600 l/h (see operating man-
ual of the control unit).
The Daikin Altherma EHS(X/H) controller permanently
monitors the flow of the internal heat exchanger circuit.
Various different minimum flow rates are required
depending on the active operating mode:
operating mode "Heating": 600 l/h
operating mode "Cooling": 840 l/h
Automatic defrosting function (
) active: 1020 l/h
If, at a flow rate in excess of 600 l/h, an error message
con
cerning inadequate minimum flow is displayed, you
must check the actual flow rate in the active operating
mode and rectify any possible causes of the error.
4.1.7 Configuring Screed Program parameters
(only if necessary)
With the Screed Program the flow temperature is controlled on
the basis of a pre-set temperature profile.
Further information on the Screed Program, its activation and
expiry, see the operating manual of the control unit.
After expiry of the Screed Program the RoCon HP control unit
continues to operate in the previously set operating mode.
Unless configured previously, the following tasks need to be
carried out in conclusion.
a) Wh
en connecting without a room station EHS157034:
Set th
e heating characteristic curve or the desired flow
temperature.
b) When connecting with a room station EHS157034:
Activate th
e room station.
Set the heating characteristic curve or the desired flow
temperature. If required, activate the parameter [Room
Influence] and set the preset room temperature.
4.2 Re-commissioning
4.2.1 Requirements
CAUTION!
Commissioning in frosty conditions can result in
damage to the entire heating system.
Only commission
at temperatures below 0 °C when
a water temperature of at least 5 °C can be
guaranteed in the heating system and storage
tank.
Daikin recommends that you avoid operating the
system in extremely fro
sty conditions.
The Daikin Altherma EHS(X/H) is fully connected.
The coolant system is dehumidified and filled with the speci-
fied amount of coolant.
The heating and hot water systems are fil
led and charged at
the right pressure (see chapter 6.5).
The storage tank is filled up to the overflow (see chapter 6.4).
4.2.2 Start-up
If the storage temperature falls below a certain
minimum value, the safety settings of the Daikin
Altherma EHS(X/H) prevent the operation of the heat
pump in the case of low external temperatures:
Extern
al temperature < -2 °C, minimum storage
temperature = 30 °C
Extern
al temperature < 12 °C, minimum storage
temperature = 23 °C.
Without backup-heater:
The storage tank water must be heated to the minimum
required storage temperature by an external heater.
With backup heater (EKBUxx):
With an outdoor temperature < 12 °C and a storage
ta
nk temperature < 35 °C, the backup heater (BUH) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
In order to accelerate the heating process with
the back-up heater, temporarily
Set parameter [F
unction Heating Rod] = "1"
and
Set parameter [Power DHW] to t
he maximum
value of the back-up heater.
Switch the rotary switch to operating mode
and set the parameter [1x Hot Water] to "On".
Following successful heating, reset the parame-
ters to "Off".
