Indoor unit for air to water heat pump system and options

4PW54184-1

Operation manual

12

[3] Auto restart

When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
supply failure.

Note that with the function disabled the schedule timer will not be
activated when power returns to the unit after a power supply failure.
Press the 

pr

 button to enable the schedule timer again.

[3-00] Status: defines whether the auto restart function is
turned ON (0) or OFF (1).

[4] Space heating off temperature

Space heating off temperature

[4-02] Space heating off temperature: outdoor temperature
above which space heating is turned off, to avoid
overheating.

[9] Cooling and heating set point ranges

The purpose of this field setting is to prevent the user from selecting
a wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.

[9-00] Heating set point upper limit: maximum leaving water
temperature for heating operation.

[9-01] Heating set point lower limit: minimum leaving water
temperature for heating operation.

[9-02] Cooling set point upper limit: maximum leaving water
temperature for cooling operation.

[9-03] Cooling set point lower limit: minimum leaving water
temperature for cooling operation.

[C] Setup on EKRP1HB digital I/O PCB

Solar priority mode

[C-00] Solar priority mode setting: for information concerning
the EKSOLHW solar kit, refer to the installation manual of
that kit.

[D] Local shift value weather dependent

Local shift value weather dependent

The local shift value weather dependent field setting is only relevant
in case weather dependent set point (see field setting 

"[1] Weather

dependent set point (heating operation only)" on page 

11

) is

selected.

[D-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 0°C.

[E] Unit information readout

[E-00] Readout of the software version (example: 23)

[E-01] Readout of the EEPROM version (example: 23)

[E-02] Readout of the unit model identification (example: 11)

[E-03] Readout of the liquid refrigerant temperature

[E-04] Readout of the inlet water temperature

NOTE

It is therefore recommended to leave the auto restart
function enabled.

NOTE

If the benefit kWh rate power supply is of the type that
power supply is interrupted, then always allow the auto
restart function.

CAUTION

In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.

In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation (field setting of parameter [9-03]) to
16~18°C to prevent condensation on the floor.
