1. Minimum Internal Water Volume above table is for
standard ON/OFF differential.
In case of changing ON/OFF differential, minimum
internal water volume changes as following
percentage.

2. To prevent frequent ON/OFF for no load or extremely
low load operation, system internal water volume
shall be more than above table.
ON/OFF cycles shall be maximum 6 times per hour.
(minimum 5 minutes operation and minimum 5
minutes thermostat OFF)
