Important Warning Instructions

• The temperature sensor must be installed in order to read the water temperature properly. Improper installation of the sensor can cause overheating or insufficient heating of the water. The spa manufacturer must verify if the temperature measured by the sensor is the same as the actual water temperature and that the sensor cannot be affected by external conditions (ex: air temperature).

• This control is not suitable and cannot be used for gas heater applications.

• This control must always be connected to a circuit protected by a ground fault interrupter.

• Install the control on a solid surface to minimize mechanical vibrations.

• The power input cable should always be secured in place with a proper strain relief.

• A notice should be installed by the manufacturer on the finished product to notify the end user to always check the water temperature with his hand before entering the water so as to prevent burns and other injuries which may result from improper water temperatures.

• This control should not be installed in the proximity of highly flammable materials.

• This control is not protected against water infiltration. It should not be installed in a location or in a manner which could lead to contact with water.

Mode

Depending on system configuration, the ozonator can be on during the filtering cycle, always on or it may operate at the same time as the circulation pump. If a pump, blower or spa light is turned on manually, the ozonator automatically turns off and comes back on 40 minutes after last active output has been turned off. On models without circulation pump, the ozonator comes on only during filter cycles.

Depending on system configuration,the circulation pump could be either on all the time or when heating and filtering only, except if the system has been programmed to Stand-By mode with the

On/Off key. If the spa is turned off while heater is still on, the circulation pump will continue to run for 30 seconds to allow heater to cool down.

Following a power failure, the display panel will continue flashing until any key is pressed. This feature notifies you that a power failure has occurred.

The MC-MP-SBD is equipped with a sensor that monitors the air temperature in the plumbing beneath the spa. If the system detects air cold enough to freeze water in the pipes, it will activate the Smart Winter Mode for a 24-hour period. In this mode, if pumps have not been turned on within 2 hours, the system automatically turns them on for 1 minute to prevent water from freezing in pipes.

When pumps are operating in Smart Winter Mode, the "Filter" indicator will flash on the display.

Temperature

Display Unit

The water temperature can be displayed in Fahrenheit (°F) or

Alarm & Error Displays

Alarm Displays

Pump starts by itself for 1 minute on several occasions and

"Filter" indicator is flashing. (Also see page 39)

Not a bug, but a feature! The Smart Winter Mode is protecting your spa from the cold by turning pumps on for 1 minute several times a day to prevent water in pipes from freezing.

The system has detected air cold enough to freeze water in the pipes and has activated Smart Winter Mode for a 24-hour period

(when pumps are not turned on within 2 hours, they are activated).

Filter cycle has stopped and "Filter" indicator is flashing.

(Also see page 36)

Not a bug, but a feature! This indicates that either: a) the filter cycle is in a 40-minute time-out to avoid ozonator activation while the spa is being used; or b) the system has cancelled a filter cycle after 3 hours because water temperature exceeds set point by more than 2˚F in order to prevent excessive water temperature.

"Heater" indicator flashes when pump is on at high speed.

(Also see page 22)

Not a bug, but a feature! The system is turning the heater off when pump is on at high speed to limit the amount of electrical current drawn (when jumper JMP1 set to "LC" mode).

The display panel is flashing.

A power failure has occurred. Press any key to reset the system.
