Hayward Pool Products - Heat Pump Troubleshooting Guide

Loading...
Introduction The following heat pump diagnostic flow charts and accompanying wiring diagrams are to be used in diagnosing and repairing Hayward & Summit branded pool heat pump systems. They are not intended for use with any other manufacturers heat pumps. Summit Branded heat pumps are in Section 2 and have their own table of contents starting on page 32. However, there are certain portions of Section 1 that can be used on all brands, and these are denoted by underlining them in the table of contents Heat Pump pool heaters are similar to the heat pumps for home heating and cooling in that they contain refrigerant. As such, service personnel should observe EPA regulations for refrigerant handling. Pool heat pumps operate on 240 volts A/C. There is a risk of electric shock at all terminals and the heat pump should only be serviced by trained personnel. To use this guide, determine the model number of the heat pump and the nature of the problem. Refer to page one to find the appropriate page for the problem and follow the flow charts to the solution. If you have further questions Call Hayward’s tech service department at 908-355-7995

! High voltage. Danger! Use extreme caution. Do not attempt if you are not a qualified servicer. TCO models may have more than one power source!

Water Sensor failure. Check sensor with values in Chart 1. If values are not correct, replace sensor. Refer to chart, Page 24. Pg. 34 for Summit units.

NO YES

Correct wiring

Replace display and wiring harness See Note 1 Note 1 Heater runs for a while then shuts off and shows ‘HI or HP’ on display. Low water flow is normally the problem. Check filter and pump. A common problem when running unit on spa only exists in the summer when spa temperature of about 100° F is reached and the unit shuts off with the ‘HI’ fault. At higher outdoor and water temperatures a higher flow rate may be required for proper operation. The unit requires a minimum of 30 GPM, but may require more under these conditions. On 3T and 4T heat pumps this can also be a sign of a failed TXV. Check capillary tube to TXV bulb for failure. See also Pg. 6

NOTE 1

Defrost operation of heat pumps (3T and 4T Models) When the coil temperature sensor senses that the coil temp. is low enough that frost will start to form on the coil,it will cut the compressor off and continue to run the fan for 15 minutes. After 15 minutes it will check the coil temp. again. If the temperature has reached operating temperature the heat pump will resume normal operation. If it hasn’t, the heat pump will continue to run the fan with the compressor off for an additional 15 minutes before checking the coil temperature again. The heat pump will go thru a 3rd fan only cycle, and if the temperature is still not sufficient for safe, normal operation, the heat pump will shut down and display dEF. The heat pump will be off for 2 hours, and then will begin the defrost process as described above, again.

15

What’s the Problem? Running but not heating

Is air coming out of top of unit (blowing from fan) colder than the ambient (outside) air?

NO

Check unit for compressor operation by connecting manifold gauge hoses to service ports. If the compressor is running, the low side pressure will be considerably lower than the high side pressure. The high side pressure will vary depending on the water temperature and the water flow rate. If the compressor is not operating, both pressures will be the same.

YES The difference in air temperature should be around 12 to 16 degrees, less in lower humidity conditions, 6 to 8 degrees. If this is the case, the unit is operating correctly. The problem could be too short a run time. Adjust as necessary. It may also be necessary to add a solar cover to prevent evaporative cooling of the water.

YES

Low side pressure considerably lower than high side pressure?

NO TURN OFF POWER TO UNIT!

Check for burned wires on compressor, capacitor and contactor. Wires OK?

YES

! High voltage. Danger!

NO

Check compressor capacitor. Capacitor OK?

Replace wires

See Fig. N and Note 9 page 16

NO YES

Go to page 16

Replace capacitor

Check compressor for internal overload trip.

16

From Page 15

Remove wires from compressor to capacitor and contactor. Set meter to lowest Ohm setting. Check reading between the red and blue wires. Reading of infinite resistance?

NO

Compressor may be stuck. Install hard start capacitor between terminals on compressor capacitor and retry. Fig. O

YES

If compressor doesn’t start Contact Tech Support 908-355-7995 For further instruction

Overload on compressor may be open. It must cool before it will reset. To verify, check resistance between black and blue wires. If resistance here is infinite, check between red and black. The resistance here should be less than 3 Ohms. If it is, the overload is open. Once reset it will attempt to operate again.

Figure N

Capacitors

Note 9 Checking a capacitor Disconnect capacitor wires. With meter set at 20k Ohm scale, place test leads on terminals. The resistance should initially be high, then slowly drop towards zero. This will happen very quickly when checking a fan capacitor, and will take several seconds when checking a compressor capacitor. This indicates a good capacitor. If you have a reading of no resistance, (0.00 on your read-out) or if the capacitor does not cause the meter to “jump up “ to a high resistance then fall back, the capacitor is bad. If you have a capacitance setting on your meter, place the test leads across the terminals. You should see a reading of between 6 and 8 microfarads.for a fan capacitor, and 60 to 80 for a compressor capacitor.

Note 10 Hard start kit installs on compressor capacitor terminals

What’s the problem? LEAKING WATER

Is unit leaking when not running?

NOISY

YES

NO Water around unit while running is normal condensation. Unit can produce as much as 3-5 gallons of water an hour, depending on conditions. Check water around unit with a chlorine test strip. Condensation will not have chlorine. Alternately, shut unit off and allow system pump to operate for 12 hours. If water dries up, it is condensation.

Common noises and problems Grinding

Connection of remote controllers to Digital Control Heat Pumps For 2 wire remote controllers such as the Goldline AquaLogic, connect to terminals 1 & 2 on the interface board(labeled remote heat). For 3 wire remote controllers, where the heat pump retains temperature control, connect your common wire to terminal # 4, pool wire to terminal #3 and spa to terminal # 5. The heat pump must be in the standby mode for the remote to control the unit. For 2 wire air switch controls (popular in Florida) where the heat pump is controlling the temp. use terminals 3 and 4.

Wiring diagram for Non-Digital Control Heat Pumps

Connection of Remote Controllers for Non-Digital Models The mechanical control heat pumps are compatible with 2 wire remotes such as the Goldline AquaLogic. To connect the remote, remove the jumper between terminals 1 & 2 on terminal block 1(TB1) and replace it with the 2 wires from your remote. Turn the thermostat all the way up on the heat pump. These units are not compatible with 3 wire remotes. For 2 wire air switch installations remove the jumper between terminals 1 & 2 and replace it with the 2 wires from your switch. Set the thermostat on the heat pump to the desired temp.

Summit Heat Pump Tech Service Guide Defrost Operation Heat pump will operate normally until evaporator coil sensor senses an evaporator coil temperature of 24º F. At this point the control will turn the compressor off, display FS, and leave the fan running until the evaporator coil temperature rises to 42º F. Once 42º is reached the heat pump will turn the compressor back on and the heat pump will run normally. There is no time limit on the defrost cycle, it will run in this cycle as long as necessary for the heat pump to warm up to 42º. Fan Motor Replacement All Summit fan motors come with female spade connectors that mate with male spade connectors just inside the electrical box. Do not cut wires. Heat Exchanger/Condenser Replacement You have to cut the female union connectors off existing heat exchangers to remove/ replace them. New heat exchanger will come with new female union ends, and nipples to attach. Do not attach either the nipple or the union until the heat exchanger has been installed into heater. Heat exchanger will not set in heat pump with nipples attached. See picture above for technique to cut unions using wire saw.

TO REPLACE HEAT EXCHANGER/CONDENSER 1. Cut water lines outside unit (see picture above) 2. Cut liquid and hot gas lines in a convenient place to reconnect later. 3. Cut tie-wrap on front of condenser 4. Lift condenser out of heat pump 5. Install new condenser 6. Cut hot gas and liquid lines attached to new condenser to match lines from unit and braze in. 7. Glue in nipples and male union section that come separate from condenser

Setting the HPEC-003 for use with an external controller For use with an Aqua-Logic type controller (temperature controlled by external device) 1. Turn heat pump on 2. Set pool temperature to off. 3. Set Spa temperature to 104⁰ 4. From settings menu (see previous page) scroll to P_S 5. Press up arrow and “E” should show on display. 6. Attach two wires from controller to P & S terminals on back of display board 7. External controller will now control heat pump. This control is not designed for use with a 3 wire external control system. However, it can be used with a switch type controller when the temperature is set on the heat pump And the switch simply changes the control from Pool to Spa. Follow the instructions above EXCEPT: Set your pool temperature to the desired temperature Now the heat pump will be in the pool mode except when the switch is engaged at which time It will switch to Spa mode for as long as the switch is closed.

41

Remote Connections for old style control boards Summit units are compatible with 2 wire remotes. They are also compatible with systems that have the pool on all the time but use a spa flow switch to change the heat pump over to spa temperature control. For two wire remote applications, connect the two low voltage wires from the remote to terminals 18 and 19 on the control board, and clip red wire located at top edge of control board marked J1. Set pool thermostat to off (below 61º F), and the spa thermostat to 104º F (maximum). • If the pool thermostat is not set to off the heat pump will switch to pool mode and continue to run after the remote is no longer calling for heat as long as the filter pump is running and the pool thermostat is not satisfied. If the spa thermostat is not set to maximum, the remote will not be able to control the heat pump above the set point on the heat pump control.

• For use with spa water flow switch controls, connect the 2 wires from the switch to terminal 18 & 19 as above, and then set your pool and spa thermostats to the desired temperature. On closure of the flow switch the heat pump control will switch from pool to spa settings. When flow switch opens the control will revert to pool mode. It will always be in either pool or spa mode with this configuration. If the pool is not to be heated, set pool thermostat to off position.

42

Replacing Existing Board With New HPEC-003 Control Board The new control board in Summit units has a different wiring configuration than the old style board. Part number is the same for both SMX306000016. Old style board has 3 low voltage wires from transformer- blue common, yellow 24v, and white 12v. New Board has only 2 low voltage wires from transformer. Do not use the white wire from transformer attached at terminal 16 on old board, Tape off terminal end to avoid shorting. The brown and black wires connected at the fan relay on the old board are attached at the terminals marked FAN on the new board. All other wiring will be the same between the two boards. Mounting screws are different, use new screws on replacement.
