Instead of setting the fl ow rate for the system using a fl ow rate limiter, it is better
to adjust the fl ow rate using the switch on the pump and by means of the “max.
speed” setting on the controller (see 7.9.4). This saves electricity!
The service values (see 9.) include not only current measurement values and
operating states, but also all of the settings for the controller. Write the service
values down just once after commissioning has been successfully completed.
In the event of uncertainty as to the control response or malfunctions the service
values are a proven and successful method for remote diagnosis. Write the ser-
vice values down (see 9.) at the time that the suspected malfunction occurs. Send
the service value table by fax or e-mail with a brief description of the error to the
specialist or manufacturer.
In program 13 “Solar with storage tank and pool” the charging of the pool, e.g. for
winter operation, can be switched off using a simple function. To do this, simply
press and hold the “esc” key down for several seconds on the diagram/overview
screen. A message appears on the display as soon as the pool is switched off or
when the pool is switched on again.
In program 1 “Solar with storage tank” the mechanical relay R2 switches together
with the speed-controlled output R1. Relay output R2 can be used to operate
larger loads up to 460VA, as well as valves or auxiliary relays with low power.
Programs 20 + 21 “Universal ∆T controller” are suitable, for example, for hydrau-
lic variants with solid-fi red boiler, follow-on storage tank charging, storage tank
transfer, heating circuit return lift, etc.
The Operating hours displayed in the “Analysis” menu are solar operating hours.
This therefore only takes into account hours in which the solar pump is active. In
the universal programs 20 + 21 the times refer to relay R1.
To protect against loss of data, record any analyses and data that are particularly
important to you (see 2.) at regular intervals.
