1. START UP AND OPERATION

In the Inox Titanium water-water heat exchanger the heat is transferred from the
boiler cycle to the pool water cycle.
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
2.
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.
