In my idea the thermostat controls the zone temperature of the type690 and gives the control signal to the heat pump.
I try to attach the image again.

Without seeing your project my first guess is that you don't have
anything turning the pumps on; the thermostat is only connected to the
heat pump.
Beyond that, PLEASE add some pipes between the components and make sure
you are operating at reasonable time steps - 5 minutes or so.
