When the thermostat opens, the electrical heating element turns off, no longer heating the air. The

hydraulic fluid flow is diverted to the condenser fan motor, M1C, before returning to the oil cooler, filter, and

reservoir. This is accomplished by de-energizing (closing) SV5 and leaving solenoid valves SV2 and SV9

energized.
