E 4 - Useful hints and tricks
Instead of setting the flow rate for the system using a flow rate limiter, it is better to adjust the flow
rate using the switch on the pump and by means of the „max. speed” setting on the controller (see
D 7.9.4). This saves electricity!
The service values (see D 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 service values down (see D 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.
In program 1 „Solar system 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
(pumps, valves or auxiliary relays).
In program 13 „Solar system 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.
Programs 19 + 20 „Universal ∆T controller” are suitable, for example, for hydraulic variants with
solid-fuel boiler, follow-on storage tank charging, storage tank heat exchange, heating circuit
return raising, 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 19 + 20
the times refer to relay R1.
To protect against loss of data, record any analyses and data that are particularly important to you
at regular intervals.
