Operating Mode - Riello SC ACS 160 Manual

3. OPERATING MODE

Auto
The automatic mode is the normal mode of the controller.
A correct controller function under consideration of the
current temperatures and the set parameters is only pres-
ent in automatic mode! After an interruption of the mains
voltage, the controller automatically returns to the last op-
erating mode selected.
Manual
The individual relay outputs, v outputs and the connected
consumers can be checked for proper functioning and
correct assignment.
b
The operating mode ‚Manual' may only be used by specialists for brief function tests, e.g. during commissioning!
Function in manual mode: The relays and thus the connected consumers are switched on and off by pressing a key,
with no regard to the current temperatures and set parameters. At the same time, the current measurement values
of temperature sensors are also shown in the display for the purposes of function control.
Off
b
If the operating mode "off" is enabled, all control functions are turned off. The measured temperatures are displayed
for the overview.
4. SETTINGS
b
By no means does the controller replace the safety
appliances on site!
Tset
Setpoint temperature at the flow sensor.
The LFWC controller operates on the condition that the
hot water temperature/tap temperature measured at the
flow sensor is adjusted as quickly as possible and kept
constant.
Tmax
Maximum hot water tap temperature measured at the flow sensor. Exceeding this limit will cause the pump to be switched
off. If the temperature falls below the set temperature, the pump is released again.
b
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must
be provided by the customer!
Flow sensor
Selection of the flow sensor.
Circulation
If the circulation has been selected and activated in the menu Special functions/Signal V2, the following settings can be
made: See " Circulation" on page 17
Storage Heating
See " Storage Heating " on page 18
Additional Pump
See " Additional Pump " on page 18
Solar
See " Solar " on page 19
Comfort
If the comfort function is activated, the primary pump rinses through the heat exchanger every 15 minutes for 5 seconds,
so that hot water is available as fast as possible during the tapping process.
