REVO-E Heat pump 4 Function and functional schematics
4.4.1 Heating and Ventilation Mode (HV Mode)
Requirements:
–
Clamp 30 active
– HV Mode required by BEA body
Both modes are required directly by the BEA body.
CAN messages from the BEA body to SC620 for defined
speed of double radial blowers and position of air flaps
(fresh air / recirculating air).
Water valves are controlled by the BEA body directly.
