FIG. 15 - Typical schematic drawing of the system sensor positions
Each unit has a ULWT sensor that is connected to terminals 1 and 2 of terminals BC2. The factory master unit comes with
two sensors: REWT & RLWT. REWT will always be connected to terminals 3 and 4 of terminal block BC2 in the master unit
(address 0000). RLWT will always be connected to terminals 3 and 4 of terminal block BC2 in the slave unit 2 (address
0001). If the system is just one unit, RLWT must be discarded.
The layout of the modules and pipeline design depend on the characteristics of each installation. It is the customer's
responsibility to design their piping and install the modules meeting the minimum requirements required by Carrier.
The piping design shall provide for a correct distribution of fluid flow to the modules in the system, avoiding excess
or lack of flow in each of the modules.
Water fl ows in the chillers
The Aquasmart system operates with the concept of fl ow through the modules in operation, allowing a more accurate
temperature control. To ensure a constant outfl ow of chilled water, it is advisable to use a primary and secondary ring,
resulting in greater accuracy in the outlet water temperature.
In the use of primary and secondary circuits, it is common to use a cooled water tank (chillers system outlet) and a
return water tank.
