Power On, Startup

Before applying power to the heat pump, check the following items:

1. Water supply plumbing to the heat pump is complete and operational.

2. Low voltage wiring of the thermostat and any additional control wiring is complete.

3. Set thermostat to the OFF position.

4. All high voltage wiring is correct including fuses, breakers, and wire sizes.

5. The heat pump is located in a warm area above 50°F [10°C]. Starting the system with low ambient

temperature conditions is more difficult.

6. Manually open water valve on well system to check flow. Never operate the system without adequate

source water ground loop or open loop supply.

7. You may now apply power to the unit. A 1 to 5 minute delay on power up is programmed into the heat

pump before the compressor will operate. This delay prevents short cycling of the unit.

• During this time the blower may be active.

• Verify water flow rate and temperature of the source side flow to be at recommended levels.

8. The source side water flow rate is at the required level, see specification page. Low water temperature

starting may require flow reduction until the system is up to operating temperature.

The following steps will assure that your system is heating and cooling properly. After the initial time-out

period is completed the heat pump is now ready for operation. Note: EZGEO, HC112, sequence charts (mode

A, B, C, D) determine compressor staging.

1. Place the thermostat to the “HEAT” position. Turn the thermostat up to activate a call for heat. The

compressor should start.

2. After the unit has run for about 3 minutes, check the source side supply and return water temperature.

water temperature decrease is normal in the heating mode, but the specific operating water temperature can

effect the water flow rate (GPM) stated in the specification table.

3. Verify warm air temperature rise and loop source water decrease are approximately as stated in the

specification table, page 3.

4. Turn the thermostat to the off position. The compressor will shut down in a few seconds.

5. Place the thermostat in the “COOL” position. Next turn thermostat down to active a call for cooling. The

compressor will start after a 5 minute anti-short cycle period from its last shutdown.

6. After the unit has run about 3 minutes, check the source side supply and return water temperatures. A water

temperature rise is normal in the cooling mode.

7. Verify cool air temperature drop and loop source water increase are approximately as stated in the

specification table, page 3.

8. Instruct the owner on correct operation of the thermostat and heat pump system.
