Zone 1 Heat and Zone 2 Heat
The CIS is closed so high pressure refrigerant
vapor leaves the compressor and flows through
the DPR to Zone 1 and Zone 2 hot gas lines and
through HGS1 and HGS2 into both evaporators.
There, the refrigerant heats both evaporators and
condenses into high pressure liquid. The
refrigerant flows through the open suction line
solenoids and back to accumulator.
In the condensing unit, the CIS valve closes and
opens to regulate head pressure. The purge valve
is opened continuously during heat to drain the
condenser coil.
