This submenu allows testing analog (contacts) and digital (0-10V) outputs that manage pumps start/stop, both
programmable relays, 23
0V Triac output and valve’ signal. It is possible to run an automatic sequence or to test
manually each output individually.
In case of Auto test (automatic sequence), it is possible to reduce or increase tests’ temporizations. Pump,
valve and relays test times can be adjusted individually. The time test value will impact on the total auto test
time sequence.
