Time Functions
The system regulator provides 3 independent time functions to implement the time-controlled functions
(time clocks).
To activate a time function, select the required time function in the menu 'Settings -> 'Service' ->
'Functions' -> 'Time functions' and press the OK button for 2 seconds (
-->
:
).
The most important Settings for each activated time function can be individually customized. In
addition to selecting the output to be controlled, each clock can be programmed up to 5 different
switching times for work days (Mo to Fr) and an additional 5 switching times for weekends (Sa and
Su).
Note:
When setting the individual time windows, ensure the switch-on time is always
before the corresponding switch-off time. If a time function must be active between
9:00 P.M: and 6:00 A.M., for example, 2 time windows must be programmed: 9:00
P.M.– 11:59 P.M. and 12:00 A.M.– 6:00 A.M.!!!
The relay outputs "R1 (regulator)" to "R4 (regulator)" or the outputs "R1 (IOBox)" to "R3 (IOBox)" are available on each of the
four possible add-on devices.

Pipe Coll./Interval
The system regulator provides 2 interval functions to implement the interval switches.
In some system arrangements a low minimum flow rate, for example, may be required to record real
measuring values. Such an arrangement can be found, for instance, when using vacuum pipe
collectors. Since the temperature sensor in pipe collectors is usually only installed in the collector line,
the measured collector temperature is often far below the real pipe temperature when the pumps are
stationary. Due to their high efficiency the collector can, however, quickly reach high temperatures.
This function in the solar pump is switched on in adjustable intervals to transport the temperature from
the pipes to the sensor. This clearly improves the system’s switching procedure.
To activate an interval function, select the required interval function in the menu 'Settings -> 'Service' -
> 'Functions' -> 'pipe coll/interval' and press the OK button for 2 seconds (
-->
:
).
In addition to the output control, the interval and on-time period is adjustable. This facilitates the
simple implementation of different interval requirements.
The interval outputs "R1 (regulator)" to "R4 (regulator)" are available on the regulator or the outputs "R1 (IOBox)" to "R3
(IOBox)" are available on each of the four possible add-on devices (for additional IO boxes see ch. 9.1).
5.6
Heat Meters
The regulator provides 3 independent heat meters.
The corresponding thermal output is calculated via a volume measuring component with a pulse
output (see page 7 for connection) and the differential temperature between the supply and return line,
and the total thermal quantity is constantly added up. The user can record the total thermal quantity
over a chosen period and then reset this amount again. To reset, press the OK button (hold for 2
seconds).
To activate a heat meter, select the required meter in the menu 'Settings -> 'Service' -> 'Functions' ->
Heat meters' and press the OK button for 2 seconds (
