ECO MODE

Since navigation to a new operating mode is always made from the
currently enabled mode, you may need to scroll in an anti-clock­wise direction. All operating modes, apart from DHW mode, apply
to both heating and DHW.

Standby mode

Frost protection is activated for heating and DHW mode. The set
DHW value is fixed at 10°C, the set heating flow value is calculated
based on a set room value of 5°C.

Application: During prolonged periods of absence, e.g. holidays.

Programmed operation

Heating according to the time switch program (applies to heat­ing circuit1 and heating circuit2). Changeover between comfort
temperature and ECO temperature.

DHW heating according to the time switch program; changeover
between comfort temperature and ECO temperature.

The remote control is only effective in this operating mode.

Application: When DHW and heating are required.

Comfort mode

The heating circuit (HC) is constantly held at the comfort tem­perature (HC1 and HC2). DHW heating according to time switch
program.

Application: Low energy houses without setback mode.

ECO mode

The heating circuit is constantly held at the ECO temperature (ap­plicable to HC1 and HC2). DHW heating according to time switch
program.

Application: During weekends away.

DHW mode

DHW heating according to time switch program. If a time program
is active, the water inside the DHW cylinder is heated to the set
comfort temperature. At all other times, the water is heated to
the set ECO temperature. Frost protection is activated for heating
mode.

Application: The heating season has ended; only DHW should be
provided (summer mode).

Emergency operation

This setting activates the emergency operation.

In heat pumps with an integral 2nd heat source, the NHZ stag­es (electric reheating stages) of the electric emergency/booster
heater take over DHW and central heating irrespective of the dual
mode changeover point.

For heat pumps with an external 2nd heat source, the external
heat source for DHW or central heating must be set to ON under
SETTINGS / HEATING or DHW. Only then can the operating mode
be selected. The external heat source then takes over operation
for the DHW or central heating function, irrespective of the dual
mode changeover point.

Times can be entered in intervals of 15 minutes. You can set 16:30

or 16:45 h, but not 16:37 h. Confirm your entry with OK.

Periods around midnight

Assume, for example, you want heating mode to be enabled from

22:00 h for four hours every Wednesday evening. This means the

period does not expire until the next day, Thursday, at 02:00 h.

However, since the day ends at 00:00h, two switching time pairs

are necessary for the required program. First, program the period

22:00 to 00:00 h for Wednesday, then 00:00 to 02:00 h for Thursday.

5.3.2 DHW PROGRAM

In menu item DHW PROGRAM you can determine the times during

which DHW heating to the set comfort value should take place.

At all other times, DHW is heated to the set ECO value. You can
adjust the set values under menu item SETTINGS / DHW / DHW
TEMPERATURES. The DHW circulation output is also switched in
line with the times programmed here.

You can set your DHW heating as follows:

- For each individual day of the week (Monday - Sunday)

- Monday to Friday (Mon - Fri)

- Saturday and Sunday (Sat - Sun)

- the whole week (Mon - Sun)

You can set three switching time pairs for each of these options.

Exception: If you want to heat DHW from 22:00 h until 06:00 h the
following day you will need two switching time pairs.

Example:

You would like to heat DHW twice daily, e.g. from 22:00 h until
06:00 h the following day, and then from 08:00 h until 09:00 h.

As the day begins at 00:00 h, programming for this example must
again start at 00:00 h.

- The first switching time pair runs from 00:00 h until 06:00 h.

- The second switching time pair runs from 08:00 h until
09:00h.

- The third switching time pair runs from 22:00 h until 24:00 h.

5.3.3 PARTY PROGRAM

In the party program you can extend the comfort mode for heating
by a few hours.

5.3.4 HOLIDAY PROGRAM

In the holiday program, the heat pump system runs in ECO mode
and frost protection for DHW heating is enabled.

For both the start and end of the holiday, enter the year, month
and day. The start time is 0:00h on the first day of the holiday. The
end time is 24:00h on the day the holiday ends. After the holiday
period has expired, the heat pump system switches back to the
previous heating and DHW program.

5.3.5 HEAT-UP PROGRAM

Note

Menu item HEAT-UP PROGRAM is protected by a code
and can only be accessed and adjusted by a qualified
contractor.

Heat-up program for underfloor heating systems

Use the heat-up program to dry your screed with a defined tem­perature profile. To prevent damage to the appliance and/or the
installation, observe the following differences between air | water
heat pumps (WPL) and brine | water heat pumps (WPF):

- WPL: Where return temperatures are < 25°C, the heat-up
program / screed drying must be carried out via the emer­gency/booster heater. The process must not be carried out
via the heat pump – such low system temperatures during
the defrost cycle mean that the appliance may not be protect­ed from frost during the defrost cycle. If the return tempera­ture rises > 25°C the heat pump can take over screed drying.
For this, set parameter “LOWER APP LIMIT HZG” to -20°C.

- WPF: The heat-up program / screed drying must be carried
out via the emergency/booster heater. Never use the heat
pump to perform screed drying as this would place too high
a demand on the heat source and could damage it.

If you use the heat-up program, input the following settings at
the heat pump manager:

First set parameter “LOWER APP LIMIT HZG” to 30°C.

There are a total of 6 parameters that serve to determine the tem­peratures and periods for the heat-up program. These 6 parame­ters can be adjusted in sequence as soon as the heat-up program
is activated. The program is started with the HEAT-UP PROGRAM
parameter and the setting ON. Please note that depending on the
system temperature it may take some time to reach the required
low end temperature.

OPERATION

Menu structure

www.stiebel-eltron.com WPM 3| 15

The low end temperature (parameter LOW END TEMPERATURE)
is held for the selected time (parameter DURATION BASE TEMP).
After expiry of this period, the system heats to the maximum low
end temperature (parameter MAXIMUMTEMPERATURE) using
an increase K/day (parameter RISEPERDAY) and holds this max­imum temperature for the selected time (parameter MAXTEM­PERATURE DURATION). The system subsequently returns to the
low end temperature using the same steps as for heat-up.

If a heating buffer cylinder has been integrated into the system,
the temperature in the buffer cylinder is controlled solely via the
return sensor (fitted at the base of the buffer cylinder). If only the
direct heating circuit 1 is operational, the set values are reduced
by 5K to even out temperature differences in the buffer cylinder.
If 2 heating circuits are operational (second heating circuit is for
underfloor heating system), the mixer in heating circuit 2 regulates
down to the selected set values. The pump for heating circuit 1
is not controlled.

During the heat-up program the appliance often reaches maxi­mum output. For this reason, energy consumption and noise levels
are comparatively high during screed drying.

After the heat-up process all modified parameters must be reset
to their standard values or system values.

Emergency operation is not possible while the heat-up program
is active.

5.3.6 SILENT PROGRAM 1

For HP types 1/1* (not for WPL 34/47) and 4/4*, the fan speed is
reduced. This reduces the sound level emitted by the heat pump.

For HP types 3/3* and 5/5*, both the fan speed and the compressor
output can be reduced. Both options can be set independently of
one another.

5.3.7 SILENT PROGRAM 2

In this program, the air source heat pump is switched off for the
entire set period and only the internal or external secondary heat
generator is used for heating.

PLEASE NOTE: This program may result in high electricity bills.
