Control system automatically heat-up procedure
1. Preparation stage
Once reconnected to power or if the water temperature is 1℃ below the user setting temperature at least 10 minutes after entering the waiting stage, the heater enters the preparation stage.‘PUMP WORKING’indicator lights. If hint message ‘’ does not appear on the panel within 2 minutes, and the water temperature is 1℃ below the user setting temperature after 2 minutes, the heater enters next stage pre-heat stage.
2. Pre-heat stage
In this stage, heater heats up for 10 seconds and waits for 90 seconds. ‘Heating’ indicator lights for 10 seconds. If hint message ‘’ does not appear on the panel and the water temperature is 1℃ below the user setting temperature, heater enters next stage heat-up stage.
3. Heat-up stage
In this stage, all heating elements turn on, and heating indicator turns on as well. If hint message ‘’ does not appear, heater will heat up to 1℃ above the user setting temperature, then heating indicator blinks for 2 minutes. After that, circulation pump turns off for models with circulation pump control. Heater enters next stage waiting stage.
4. Waiting stage
Waiting stage lasts for at least 10 minutes. 10 minutes later, if the water temperature is 1℃ below the user setting temperature, the heater jumps to preparation stage, otherwise, it remains in the waiting stage.
The automatically heat-up process is non-stopping and will continue to circulating through all stages until the control system or heater is power off. You could ask for models with separated circulation pump control function.

Unique control system
1. The flow-temperature sensor is always under the control of software, accurately monitoring the temperature status of the whole system, and then adjust the settings to maintain the water temperature and protect the heater from unexpected situations.
2. No mechanical sensors, avoid any mechanical failure to affect the function of the heater.
3. Avoid affection of ion accumulation to mechanical sensors.
4. Greatly reduce unnecessary circulation cycles, prolong the life of circulation pumps and save more energy.
Before using the installation requirements:
1. The power supply voltage and the voltage marked on the machine to be consistent, deviation of
supply voltage and the rated voltage is not more than ± 10%.
2. The sensor should maintain an appropriate distance from the power lines, avoid contact or close.
3. The strict distinction between sensors, power lines and the output relay interface.

With Exclusive built-in flows switch
These pool and spa heaters feature a flows switch to prevent operation
when there is no water flows.An all stainless steel tank for long life and corrosion
resistance is also standard.A vailable in single phase and three phase configurations.
The heater is suitable for indoor or outdoor installation.See figure 1 for piping
connections and figures 2A and 2B for electrical connections.The heater should be securely
mounted to a smooth,flat surface.It may be conveniently located next to the filtration
equipment.Leave minimums clearance of 9 inches on the left,12 inches both above and to the front
and 6 inches on the back for service entrances and access.

Note:
This can only be used in pools around 8-10 cubic meters.
