REGULA grandis 650 HK

The grandis 650 HK is a highly flexible heating and solar circuit controller for the control of complete heating systems.

Two integrated heating circuits (up to four when flex 400 extention 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.

7 outputs 230V AC
  3 control outputs for HE pumps PWM o. 0-10V ana.
  1 potential-free output
  2 interfaces for Grundfos VFS and/or flow meter
  1 radiation sensor input

  10 temperature inputs PT1000
extendable to max. (with extension modules):
  19 outputs 230V AC
   7
control outputs for HE pumps PWM o. 0-10V ana.
