MCAC-RTSM-2012-01 M-thermal Technical Manual (part 2)

1. Normal Phenomenon

1.1 The heat pump does not start immediately after the ON/OFF button on the remote controller is pressed.

 If the operation lamp lights, the system is in normal condition. To prevent overloading of the compressor

motor, the heat pump starts 3 minutes after it is turned ON.

 If the operation lamp and the "PRE-DEF indicator (cooling and heating type) or fan only indicator (cooling

only type)" light, it means you choose the heating model.

1.2 Change into the Pump mode during heating mode

When the outlet water temperature drops to the setting temperature, the compressor goes off and the indoor unit changes to pump mode; when the temperature rises up, the compressor starts again. It is the same with heating mode.

1.3 White mist comes out of outdoor unit

When the system is changed over to heating operation after defrost operation Moisture generated by defrost becomes steam and is exhausted.

1.4 Noise of heat pump’s cooling

 A continuous low hissing sound is heard when the system is in operation.

This is the sound of refrigerant gas flowing through both indoor and outdoor units.

 A hissing sound will be heard at the start or immediately after stopping operation or defrost operation.

This is the noise of refrigerant caused by flow stop or flow change.

 If the tone of operating noise changes, this noise is caused by the change of compressor’s frequency.

1.5 Dust comes out of the unit

If the unit is not run for a long time, the dust has gotten into the unit.

1.6 The units can give off odors

The unit can absorb the smell of rooms, furniture, cigarettes etc., and then emit it again.

1.7 The outdoor unit fan does not spin

The speed of the fan is controlled in order to optimize product operation. In heating mode, when the system defrosting, the fan of outdoor unit will stop

MCAC-RTSM-2012-01 M-thermal Technical Manual (part 2)

2. M-thermal system protection in Common

2.1 Compressor protection.

When the power is on, or the machine stops then restarts right away, outdoor unit will run in 3 minutes to protect the compressor from too frequent starts and stops.

2.2 When the protection device functions, running stops. Refer to the following:

① Forced to start but not possess the start article, and display light lights. ② When cooling running (the operation is cooling), inlet and outlet of outdoor unit are blocked, outside

strong air blows into outdoor unit’s outlet. ③ When heating running, dust adheres to air filter to block inlet or outlet of outdoor unit. Note: when protecting, please cut the manual power switch. After checking the reason and solving it, restart.

2.3 Power fails. ① If the power supply fails while machine is running normally, system will record this. ② When the machine is powered on(power-on) again, the running light of wire controller would flash to inform user about this.

③ Press the on/off key of wire controller to confirm this before restart the system.

Note: When running, if system takes place mistaken operation or lighter, please pull down the power supply switch to cut it off. Before restarting machines, please press the on/off key again as above.

3. Trouble and causes of heat pump

If one of the following malfunctions occur, stop operation, shut off the power, and contact with your dealer.

 The lamp is flashing rapidly after turn off the power and turn on again.  Remote controller receives malfunction or the button does not work well.  A safety device such as a fuse, a breaker frequently actuates.  Obstacles and water enter the unit.  Water leaks from indoor unit.  Other malfunctions.

G. "P1": High pressure protection

Outdoor Unit Display

P1

Error Explanation

The protection device circuit checks continuity in high pressure switch

Supposed Causes

1. Refrigerant is excess.

2. Refrigerant does not loop smoothly.

3. The refrigerant loop contains air.

4. Control board is defective.

Troubleshooting

P1: High pressure protection (R22 refrigerant system protects

at 3.3Mpa, recovers at 2.4MPa; R410 refrigerant system

protects at 4.4MPa, recovers at 3.2MPa).

Heat exchanging of ODU is not efficient. This may be

caused by dirty heat exchanger, abnormal ODU fan running, air flow keeping off to the heat exchanger,

ODU are too near to each other.

System's liquid refrigerant loop is blocked. This may be caused by blocked valve, pressed tube, closed blocked valve.

Refrigerant is excess. In this circumstance, the

refrigerant's low pressure is high, so is the high pressure side, while the discharge

temperature is low.

System contains air or nitrogen. In this

circumstance, the high pressure is high, the current is large, the discharge temperature is

high, compressor makes noise

Chip is defective or incorrectly installed. Or the high pressure sensor is disconnected.

Control board is defective.

Check the system and fixed up the error.

Check the system and get rid of the block, and make the loop smooth.

Discharge part of the refrigerant. Add some oil to the system if it

leaks during the discharge.

Discharge the refrigerant. Then vacuumize the

system and refill the refrigerant. Add oil to the

system if it leaks.

Reinstall the chip or replace it with a fine one.

Replace the main control board.

MCAC-RTSM-2012-01 M-thermal Technical Manual (part 2)

H. "P2": Low pressure protection

Outdoor Unit Display

P2

Error Explanation

The protection device circuit checks continuity in low pressure switch

Supposed Causes

1. Faulty low pressure switch

2. Refrigerant is not enough.

3. Refrigerant does not loop smoothly.

4. Efficiency of indoor heat exchange is low.

5. Control board is not defective.

Troubleshooting

P2: Low pressure protection (R22 refrigerant system protects

at 0.03Mpa, recovers at 0.1MPa; R410 refrigerant system

protects at 0.05MPa, recovers at 0.15MPa, or protects at

0.14MPa, recovers at 0.3MPa).

Refrigerant is not enough or the

system leaks refrigerant.

System's gas side is blocked. Phenomenon

may be discharge temperature is high, low pressure is low, current is small. These are

caused by closed EXV valve, closed stop valve

or blocked filter.

Heat exchanger of IDU is inefficient, which

may be caused by the dirty exchanger or filter, block of air flow, the fan not running

or running too slowly.

Chip is defective or incorrectly installed. Or the low pressure sensor is disconnected.

Main control board is defective.

Reinstall the chip or replace it

with a fine one.

Replace the main control board.

Check the system

over and eliminate

the obstacles.

Clear away the block.

Add refrigerant or

fix up the system.

Clean the filter. If the

system is block by ice, the

system should also be clean.

1.2 Powering up the indoor unit

When power supply to the indoor unit is turned on, “0” is displayed on the user interface during its initialization, which might take up to 30 seconds. During this process the user interface cannot be operated.

2 Setting the pump speed

The pump speed can be selected on the pump. The default setting is high speed. If the water flow in the system is too high (e.g., noise of running water in the installation) the speed can be set to low speed.

Note: The speed dial on the pump indicates 3 speed setting.

The available external static pressure (ESP, expressed in mmH2O) in function of the water flow (l/min) is shown in the previous section.

CAUTION:

If the external pressure loss of the water circuit is too high, it is necessary to install an auxiliary pump. Fail to install an auxiliary pump will result in cooling/heating capacity reduction.

3 Field Settings

The indoor unit should be configured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user demand. These field settings are accessible and programmable through the user interface on the indoor unit. Each field setting is assigned a 4-digit number or code, for example, “3-1-15”, which is indicated on the user interface display. The first digit “3” indicates the “first code” or field setting group. The second digit indicates the second code. The last 2-digit number “15” indicate the value of code “3-1”.

A list of all field settings and default values is given under “Field settings table” . In this same list,
