Per output Q5
P er output ZX1
Output P1 makes possible the control of variable speed pumps with a pulse-width-
modulated low voltage signal.
The relay terminal connections of the relevant pump in that case do not change;
they will only be complemented by the PWM control line.
The corresponding TRIAC output for the pump is switched ON/OFF, but not
modulated.
None
O utput P1 is not controlled.
Per output Q5
The low voltage signal is calculated and issued for collector pump Q5.
Per output ZX1
The low voltage signal is calculated and issed for the pump connected to relay
output ZX1 (Q4, Q16, K9, Q11 or Q10).
