o.
DHW ECO mode Learning Days
3 days
Range 1 to 10: Number of days the ECO mode
uses to learn the Tankless DHW usage habits.
Rolling counter. If set to 0 Opentherm will control
Eco Comfort Mode Occupied or Un-Occupied.
P
Space Heating Delay after
the boiler reaches the target
temperature
2 min
Range 0 – 15 min: The boiler will remain off for X
min to help reduce short cycling when the heating
load is smaller than the min firing rate.
