The floor heating loops require a lower water temperature in heating mode compared to radiators or fan coil units.
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.
1) Make sure to connect the SV2/SV3 terminals in the wired controller correctly,please refer to 8.8.6/2)
2) Thermostat wires to the correct terminals and to configure the ROOM THERMOSTAT in the wired controller
correctly . Wiring of the room thermostat should follow method A/B/C as described in 8.8.6 "Connection for other
components / 6) For room thermostat".
1) Zone 2 can only operate in heating mode. When cooling mode is set on user interface and zone 1 is OFF, "CL"
in zone 2 closes, system still keeps "OFF". While installation, the wiring of thermostats for zone 1 and zone 2
must be correct.
2) Drainage valve(9) must be installed at the lowest position of the piping system.
