Notes:
1. The example is just for applicaon illustraon; please confirm the exact installaon method according to the installaon manual.
Space heang
Cooling or heang mode is set via the room thermostat, water temperature is set on the user interface. 1) When any “CL”
of all the thermostats close, system will be set at cooling mode. 2) When any “HL” of all the thermostats close and all “CL”
open, system will be set at heang mode.
The circulaon pumps operaon
1) When the system is in cooling mode, which means any “CL” of all the thermostats closes, SV2(7) keeps OFF, P_o(6) starts
running;
2) When
th
e system is in heang mode, which means one or more “HL” close and all “CL” open, SV2(7) keeps ON, P_o(6)
starts running.
