Controller - Astralpool WATERHEAT EQUIPADO 20kW Manual Tecnico

ENGLISH
WATERHEAT SERIES · WATER/WATER SYSTEM
The heat exchanger is made of titanium so it is suitable for water that contains a high amount of
Cl (as brine, therapeutic or of water of sea swimming pools).
A temperature probe can be added so that the pool water temperature can be controlled.
¿Have you read and understood these instructions, mainly the chapter of safety? Only if the
answer is yes the heat exchanger can be operated.
The water-water heat exchanger could be damaged if something drops on it.
PRECAUTION
Maintenance and fixing operations must be made only when both water cycle blocking units are
closed.
• Vent both water cycles

6. CONTROLLER

Main Function: the controller is a special controller for water-water heat exchangers, it contains
1 temperature sensor (water temperature) and 1 control output (filtering pump).
Temperature Display and Controlling: it can display water temperature and control the
temperature in water tank between the temperature upper and lower limit.
External alarm: one outside alarm input, it can be set to 5 modes: always open, always open
locked, always closed, always closed locked or forbidden.
Others: temperature upper and lower limit can be set; temperature sensor error alarm and so
on.
