NOTE:
1. Ta: Average Outdoor Ambient Temperature (2 hours) is used to calculate set-point.
The conguration of this option should be done through the master controller

NOTE:
1. Average Outdoor Ambient Temperature (2 hours) is used to calculate set-point.
(3) OTC Gradient
Water target is selected by an Outside Temperature compensated (OTC) control that is dened by a di󰀨erent gradient of the
curve. The initial point of the curve is always 20ºC-20ºC (water outlet target 20ºC at outdoor ambient temperature of 20ºC).
User can edit the gradient variable.
The gradient of the heating curve describes the relation between the change in water outlet target and the change in
outside temperature.
