grandis-i – Heating and solar circuits controller
Heating and solar circuits controller grandis-i
The grandis-i is a highly flexible heating and solar circuits controller for the control of complete heating systems. It can handle two integrated heating circuits (up to 4 when flex 400 extension modules are connected). Weather-compensated, mixed or unmixed, with automatic boiler demand. Various pre-defined solar diagrams and integrated multi-function controllers for flexible system extension.
