Operating Guide ECL Comfort 210/296/310, application A230

5.15 Two circulation pumps in sequence

Application A230.2:
See also the Installation Guide (delivered with the application key)
for application specific connections.
By means of Schedule 2 (placed in Common controller settings) it
can be arranged to control the shift of 2 circulation pumps.
Control of P1 is based on the cooling demand and determines via
K1 the ON / OFF control of the pumps P2 and P3. P2 and P3 are
related to the output of the Schedule 2.
Schedule 2 is factory set to change every 21 hours during the week.
This can give an approximate even ON-time for each of the two
circulation pumps.
The factory setting can, of course, be changed.
