About Multi Room systems

• Your multi-room system has one outdoor unit connected to multiple indoor units. The capacity of the heating and cooling of the indoor units will vary from the actual rated capacity, this is because the power of the outdoor unit is distributed across all the indoor units operating at the time.
• A multi-room system allows individual temperature control of each indoor unit and ensures the units are only running when needed.

Mode selection

• The mode of operation for all the indoor units is dictated by the first unit turned on.
• For example, the living room unit is turned on in COOL mode, all the other units that are turned on will be in COOL mode. The operation modes can’t be in conflict with each other.

About your Pro Series unit

Manual button

• This button selects the mode in the following order: Auto – Forced cool – Off
• In forced cool mode, the operation light flashes. The system will then turn to AUTO after it has cooled on high for approximately 30 minutes. The remote control will be disabled during this operation.
• Off, when the display panel is turned off, the unit turns off and the remote control will be re-enabled.

Operation range limits

• The table below indicates the temperature range the unit can operate within.

• If the air conditioner operates more than 80% relative humidity (in the room), the surface of the unit may attract condensation.
• Setting the airflow louvre vertically to the floor, and operating on HIGH fan mode may help with this.

Additional functions

Auto restart after a power disruption

• If the power fails, the system will stop. When the power returns, the operation light on the unit will flash. To restart, press the ON/OFF button on the remote control, the unit will restart using the same settings. Please note, there will be a delay of approximately three minutes before the unit starts.
• This is a safety feature to stop the unit from overloading.

Louvre angle memory function

• When the unit restarts after a power failure, the angle of the louvres will automatically return to the previous set position.
• To reset the louvre, press the manual button which will reset the horizontal louvre settings.

Sleep

• This function gently regulates the set temperature to prevent excessive, draft-free, heating or cooling during sleep. It allows the set temperature to increase or decrease 0.5-1 °C in an hour, up to a maximum of 2 °C above or below the set point (over an 8-hour period).
• This function can only be activated via the remote control. Sleep is not available in FAN or DRY modes.

Follow me

• Enables the remote control, when in AUTO, COOL, or HEAT to measure the temperature at its current location and send this signal to the unit every three minutes. Measuring ambient temperature from the remote control (instead of the unit itself) will enable the unit to optimise the temperature around you for maximum comfort.

Breeze away

• Drops the fan speed and raises the angle of the louvre so air is not blown down on people that may be directly below the unit.

Defrost (dF)

• In heating mode, when frost conditions are detected (thermistor in the outdoor unit), the unit automatically operates in reverse (lasting no more than ten minutes) to warm up the outdoor coil to stop it from freezing. This means the indoor unit will stop heating and only run on a low fan speed until defrost (dF) is completed.

Setting the angle of airflow

• While the unit is on, use the SWING button on the remote control to set the direction of airflow, refer to.

Note on louvre angles

• When using COOL or DRY mode, do not set the louvre at too much of a vertical angle for long periods. This can cause water to condense on the louvre blade which will drop on your floor or furnishings.
• The angle of the louvre should not be set too narrow as condensation may form and drip into the unit.
• Do not move the Louvre by hand. This will cause the Louvre to become out of sync. If this occurs, turn off the unit and unplug it for a few seconds, then restart the unit. This will reset everything.

Remote control and functions

Auto mode
In Auto mode, the unit will automatically select COOL, FAN, and HEAT based on the set temperature. In this mode, the fan speed cannot be set.

1. Select AUTO mode
2. Set your desired temperature
3. Turn on the unit

Cool or heat mode

1. Select COOL/HEAT mode
2. Set the desired temperature
3. Set the fan speed

Dry mode

The dry mode is dehumidifying. In this mode, the fan speed cannot be set as it is automatically controlled.

1. Select DRY mode
2. Set the desired temperature
3. Turn on the unit

Wireless control is available with the purchase of an optional accessory: Wireless Module – B064869 (Smart Port kit).

Fan mode
This mode uses the fan to circulate air without changing the room temperature. In this mode swing operations for air direction can still be adjusted. In FAN mode you can’t set the temperature, so no temperature will display on the remote.

1. Select FAN mode
2. Select the fan speed
3. Turn on the unit

Setting the timer
The timer function works by adding a time after which the timer will come on and then be switched off. When setting, the time will increase by 30-minute increments with each press, up to 10 hours. After 10 hours and up to 24 hours it will increase in 1 hour increments. For example, press 5 times to get 2.5 hours, and press 10 times to get 5 hours. The timer will revert to 0.0 after 24 hours.

Cancel either function by setting the timer to 0.0 hours.

1. Press TIMER to initiate the ON time sequence.
2. Press the up or down button multiple times to set the desired time to turn on the unit.
3. Wait one second, the timer ON will be activated.
4. Press TIMER to initiate the OFF time sequence.
5. Press the up or down button multiple times to set the desired time to turn off the unit.
6. Wait one second, the timer off will be activated.

If the timers are set correctly the timer on/off icons will display on the remote, refer image above.
Timer on/off setting example
Remember that the periods you set for both functions refer to the hours AFTER the current time. In the below example once the timer button is selected (at 1 pm), the timer will come on 2.5 hours later, and turn off 5 hours later.

Swing function

• If you press the Swing button the horizontal louvre will swing up and down automatically. To make it stop press the Swing button again.
• If you continue to hold down the Swing button different airflow directions can be set. The Louvre can be moved at a certain range each time you press the button.
• When the unit is off, press and hold the Mode and Swing buttons together for one second, the louvre will open at a certain angle, which makes it convenient for cleaning. Press and hold the Mode and Swing buttons again to reset the louvres.

LED display

• Press the LED button to turn on and turn off the display. If you press the LED button for more than five seconds the unit will display the room temperature, press for more than five seconds again to revert to the set temperature.

Quiet function

• Pressing the fan button for more than two seconds activates/deactivates the ‘Quiet’ function. This function slows the speed of the indoor unit and lowers the frequency of the outdoor unit (compressor). This function is useful when you need to consider other occupants in the house (people sleeping at night), or neighbours. It may result in inadequate cooling or heating.
• Pressing the ON/OFF, Mode, Turbo or Clean buttons while operating will automatically cancel the quiet function.

FP (frost protection)

• Only used in cold climates where there is a risk of the indoor unit pipes freezing. This differs from the DEFROST (dF) function that automatically occurs in the outdoor unit (when connected to power) when frost conditions are detected, refer p.9.
• In HEAT mode press the down arrow two times (within 1 second) to activate FP. The unit will operate at a high fan speed, but at a much cooler temperature (to keep running costs down), to maintain the indoor temperature at a certain temperature to prevent freezing.
• It is used for rooms or holiday homes that are not in use in winter but could be susceptible to frost.

SET function

• Press the SET button to enter the function setting, then press SET or the up and down buttons to select the desired functions. The selected symbol will flash in the display, press OK to confirm. To cancel the selected function, perform the same steps again.
• The SET function will cycle through the following functions: Sleep > Follow Me > Wireless control

Care and maintenance

• Before cleaning or maintenance turn off your unit and disconnect the power supply.
• Pre-season inspection and maintenance, and cleaning of the outdoor unit should only be done by a licensed service provider.
• Only use a soft, dry cloth to wipe the unit clean. If the unit is especially dirty, you can use a cloth soaked in warm water to wipe it clean. Do not use water to clean the inside of the indoor unit. This can destroy the insulation and cause electrical shock.
• Do not use chemicals or chemically treated cloths to clean the unit.
• Do not use benzene, paint thinner, polishing powder or other solvents, they can cause the plastic surface to crack or deform.
• Do not use water hotter than 40 °C to clean the front panel, this can cause the panel to discolour or deform.

Air filter cleaning reminder

• After 240 hours of use, the display window on the indoor unit will flash ‘CL’. This is a reminder to clean your filter. After 15 seconds, the unit will revert to its previous display.

Air filter replacement reminder

• After 2,880 hours of use, the display window on the indoor unit will flash ‘nF’. This is a reminder to replace your filter. After 15 seconds the unit will revert to its previous display.
• To reset the reminder, press the LED button on your remote control four times, or press the manual control button three times. If you don’t reset the reminder, ‘nF’ will flash again when you restart the unit.

After long periods of non-use

If you plan not to use your system for an extended period, do the following:

• Clean all filters
• Turn on the fan function until the unit dries out completely
• Turn off the unit and disconnect the power
• Remove batteries from the remote control

Pre-season inspection
After long periods of non-use, or before periods of frequent use, do the following:

• Check for damaged wires
• Clean all filters
• Check for leaks
• Replace batteries in the remote control
• Check nothing is blocking the air inlets and outlets

Filter cleaning
The filter is held in place by retainers in the back of the air inlet. To access the filter you need to push the catches inwards to open the air inlet panel. Carefully slide the filter out.

• Clean using a soft brush and warm water.
• Dry and return the filter into the unit.

Troubleshooting

Check the following information before making a service call as some performance characteristics are a normal part of operation. If you are still unsure or concerned after reading this section, please contact Rinnai on 0800 746 624.

three-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off. Another possible cause could be a faulty remote, or the remote batteries need changing.
Unit changes from cool/heat mode to fan mode| The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again. The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
The indoor unit emits a white mist| In humid regions, a large temperature differential between the room’s air and the conditioned air can cause a white mist.
Indoor and outdoor units emit a white mist| When the unit restarts in ‘heat’ mode after defrosting, a white mist may be emitted due to moisture generated from the defrosting process.
Noisy indoor unit| A rushing sound may occur when the louvre resets its position. A squeaking sound may occur after running the unit in ‘heat’ mode due to the expansion and contraction of the unit’s plastic parts.
Noisy indoor and outdoor unit| Low hissing sound during operation. This is normal and is caused by the refrigerant gas flowing through the indoor and outdoor units. Low hissing sound when the system starts, has just stopped running, or is defrosting. This noise is normal and is caused by the refrigerant gas stopping or changing direction. Squeaking sound. This is the normal expansion and contraction of the plastic and metal parts of the unit due to temperature changes during operation.
Noisy outdoor unit| The unit will make different sounds based on its current operating mode.
Dust is emitted from the indoor or outdoor unit| The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
Unusual smell| The unit may absorb odours from the environment, such as paint, cooking, cigarettes, etc., which will be emitted during operation and cleaning.
Outdoor unit fan does not operate| During operation, the fan speed is controlled to optimise operation.
Operation is erratic or the unit is unresponsive| Interference from cell phone towers and remote boosters may cause the unit to malfunction. If this occurs try disconnecting the power and then reconnecting, and pressing the on/off button on the remote to restart the operation.
Issue| Possible causes| Solution
---|---|---
Poor cooling performance| The temperature setting may be higher than the ambient room temperature| Lower the temperature setting
The heat exchanger on the indoor/outdoor unit is dirty| Service person required to clean the heat exchanger
The air filter is dirty| Remove the filter and clean
The air inlet or outlet of either unit is blocked| Turn the unit off, remove the

obstruction and turn it back on

Doors and windows are open| Make sure doors and windows are closed while the unit is on
Excessive heat generated by sunlight| Close windows and curtains during periods of high heat or bright sunshine
Low refrigerant due to leak or long-term use| Service person required
Too many sources of heat in the room (people, electronics, etc.)| Reduce the amount of heat sources
The unit starts and stops frequently| Too much or too little refrigerant in the system| Service person required
Malfunctioning compressor| Service person required
Poor heating performance| Cold air is entering through doors and windows| Make sure all doors and windows are closed during use
The outdoor temperature is extremely low| Use a secondary heating source
Low refrigerant due to leak or long-term use| Service person required

LED screen flashing or displaying an error code
Operational codes such as ‘CL’ (clean filter), ‘nF’ (replace filter), and dF (defrost) etc. are a normal part of operation. The screen may also display an error code. Error codes begin with letters and then numbers, for example:

• E(x), P(x), F(x)
• EH(xx), EL (xx), EC(xx)
• PH(xx), PL(xx), PC(xx)

Sometimes an error code will resolve itself. If not turn the unit off, turn off the mains power to the unit, wait a few minutes, then turn everything back on. If the error code remains contact your installer or Rinnai for advice.
