The circulation pump operation 
When zone 1 is ON, P_o(6) starts running; When zone 1 is OFF, P_o(6) stops running; 
When zone 2 is ON, SV3(8.1) is ON, P_c(8.2) starts running; When zone 2 is OFF, SV3(8.1) is OFF, P_c(8.2) 
stops running . 
The floor heating loops require a lower water temperature in heating mode compared to radiators. To achieve 
these two set points, a mixing station is used to adapt the water temperature according to requirements of the floor 
heating loops. The radiators are directly connected to the unit water circuit and the floor heating loops are after 
the mixing station. The mixing station is controlled by the unit.
