Set HC
The flow temperature of the heating circuit is a function or outdoor
temperature. The heating curve slope can be adjusted depending on building
type and type of heating system. The CONTROL 602/702 calculates the
required flow temperature and operates the mixing valve to achieve this
temperature. The menu allows the following items to be adjusted individually.
For the CONTROL 602, the control of the heating circuit is only possible in
Variant B.
Room Temperature:
Target: 15...30 °C
The preset room temperature is 20 °C. If a higher or lower room temperature
is desired, it can be set here.
Heating Slope:
0,3...4,4
The heating slope required for the building location and flow temperature can
be set here.

Example:
(1.) Location: Edinburgh (from
table below: -6 °C, high
thermal inertia building
without overload capacity)
(2.) Heating temperature:
Flow 60°C/ Return 40°C
(3.) From the diagram gives a
slope of heating of 1.4, which
is set on the controller.
