5.8 2-step heating
A 2-step heating system consists of a slow main step and a fast additional step.
Typically, Cheops control is plugged into the floor heating system (main step) and the
radiators are controlled as the additional step.
Cheops controls the two steps in parallel, the additional step being controlled at a lower set
point value.
The differential between main and additional step is defined on the "Set point value"
parameter page.
Cheops drive valve actuators can be used as a continuous additional step (recommended).
Thermal valve actuators (Order No. 907 0 248) or possibly an electrical additional heater can
be used as a switching additional step.
