Sequence of Operation for Water Source Heat Pump

Cooling Cycle

• Set the thermostat for Cooling.
• If applicable, the motorized valve opens as long as the

thermostat calls for Cooling.

• This sends a 24-volt signal to the terminal to the compressor

contactor and the compressor starts.

• At the same time a 24-volt signal flows through the fan relay

and the blower starts in HIGH speed, if the unit is in Auto Fan
Mode. If the unit is in manual mode, set by the user, then the fan
continuously blows in the user set speed.

• If in Auto Fan Mode, once the thermostat is within 2 degrees of

set point, the fan drops to LOW speed.

• Once the thermostat is satisfied, it sends a 24-volt signal to the

compressor contactor and compressor turns OFF.

• If in Auto Fan Mode, this ends the 24-volt signal to the indoor

blower relay and the blower stops.

• If LOW or HIGH fan speed is manually selected the fan will

continue to blow.

Heating Cycle

• Set the thermostat for Heating
• If applicable the motorized valve opens as long as the thermostat

calls for Heating.

• This sends a 24-volt signal to the terminal to the compressor

contactor and the compressor starts.

• At the same time a 24-volt signal flows through the fan relay

and the blower starts in HIGH speed, if the unit is in Auto Fan
Mode. If the unit is in manual mode, set by the user, then the fan
continuously blows in the user set speed.

• If in Auto Fan Mode, once the thermostat is within 2 degrees of

set point, the fan drops to LOW speed.

• Once the thermostat is satisfied, it sends a 24-volt signal to the

compressor contactor and compressor turns OFF.

• If in Auto Fan Mode, this ends the 24-volt signal to the indoor

blower relay and the blower stops.

• If LOW or HIGH fan speed is manually selected the fan will

continue to blow.
