Parameter Meaning
CIRC. PUMP DC 1 0 = stop circulation pump in discharge circuit 1
1 = start circulation pump in discharge circuit 1
SHUNT DC 1 = closes shunt in discharge circuit 1
0 = shunt unaffected
= opens shunt in discharge circuit 1
CIRC. PUMP DC 2 0 = stop circulation pump in discharge circuit 2
1 = start circulation pump in discharge circuit 2
SHUNT DC 2 = closes shunt in discharge circuit 2
0 = shunt unaffected
= opens shunt in discharge circuit 2
BY-PASS COOLING 0 = closed, normal for heating
1 = open, during cooling
SYSTEM SHUNT = closes shunt
0 = shunt unaffected
= opens shunt
RET.L. HP SHUNT = closes return line shunt in systems with buffer tank
0 = shunt unaffected
= opens shunt in systems with buffer tank
REV. V. POOL 0 = reversing valve in normal mode
1 = reversing valve in pool mode
ALARM 0 = no voltage on output 201.6 External alarm
1 = 230V on output 201.6 External alarm
DIGITAL OUT 5V 0 = no voltage on output 204.1
