12-9. Multi-unit system ON / OFF conditions
In Easy-link system and Multiple-system, the amount of T-M32’s called on to activate depends on the
FLOW RATE and the SET TEMPERATURE.
1.
Condition required to activate an additional T-M32:
Flow rate required to activate additional T-M32 = A × n
Where n= number of currently activated T-M32’s
and A is dependent on the set temperature. See table below:

In the case of reducing down from two units T-M32’s to one T-M32: Flow rate = A / 1.7
B.
All other cases: Flow rate = A × (n - 2)
