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 12.9.4). This saves electricity!
The
service values
(see 15.) 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 15.) 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.
Program 2
“
Universal
ΔΔΔΔΔ
T controller
”
is suitable, for example, for
hydraulic variants with solid-fired boiler, follow-on storage tank
charging, storage tank transfer, etc.
To protect against loss of data, record any
analyses
and data that
are particularly important to you (see 7.) at regular intervals.
In program 1 „Solar with storage tank“ relais R2 is switched on
whenever R1 is active. At R2 voltages up to 460 VA or valves or
additional relais with lower voltages can be used.
Using the Energy saving mode (10.6) can reduce additional heating
to a minimum.
