Indication of sensors 3 and 4 Indicates the current temperature of the corresponding ad-
ditional sensor (without control function).
• S3
: temperature sensor 3
• S4 : temperature sensor 4
S3, S4:
Sensor temperatures
Display range: -40 ... +500 °F
[-40 ... +260 °C]
Indication of return temperature If energy metering is active, the temperature at sensor 4 is
indicated as TR.
TR:
Return tempe rature
Display range: -40 ... +500 °F
[-40 ... +260 °C]
Note:
S3 and S4 will only be indicated if the temperature
sensors are connected.
Indication of current pump speed Indicates the current pump speed of the solar pump.
n %:
Current pump speed
Display range: 30 ... 100 %
Operating hours counter The operating hours counter accumulates the solar operating
hours of the relay (
h P). Full hours are displayed.
The accumulated operating hours can be set back to 0. As
soon as one operating hours channel is selected, the symbol
is displayed.
Î In order to access the RESET-mode of the counter, press
button 3 for approx. 2 seconds.
The display symbol will flash and the operating hours
will be set to 0.
Î Confirm the reset with button 3 in order to finish the reset.
In order to interrupt the RESET-process, do not press a button
for about five seconds. The display returns to the display mode.
h P:
Operating hours counter
Display channel
kWh/MWh: Heat quantity in
kWh / MWh
Display channel
Indicates the energy gained in heat quantity – only available
if energy metering (OHQM) is activated.
The flow rate as well as the reference sensors S1 (flow) and
S4 (return) are used for calculating the heat quantity supplied.
It is shown in kWh in the channel
kWh and in MWh in the
channel MWh. The overall heat quantity results from the sum
of both values.
The accumulated heat quantity can be set back to 0. As soon
as one of the display channels of the heat quantity is selected,
the
symbol is permanently shown on the display.
Î Press button 3 for about 2 seconds in order to access the
RESET mode of the counter.
The display symbol will flash and the heat quantity value
will be set to 0.
Î In order to finish this process, press button 3 to confirm.
In order to interrupt the RESET-process, do not press a button
for about five seconds. The display returns to the display mode.
