2.7.6. Internal water coil option
The internal water coils are supplied with a motorised, pre-wired 3-way valve, a "Water Bat" control cable and a "TAG" temperature probe (to measure
the temperature of the fluid circulating in the coil and prevent the water circuit from potentially icing up).
The "Water Bat"cable and the temperature probe are connected to one side on the electronic board. On the other side, they are on stand-by in the
side rail, air supply side, ready to be connected by the fitter.
Connect the 3-way valve and the coil collectors hydraulically.
Connect the male connector of the "Water Bat" cable to the female connector on the servomotor.
Caution:
the electrical connections on outside equipment or equipment located in a moist environment must be watertight. It is recommended to
protect the connections between the servomotor cable and the "Water Bat" cable by at least class IPX5 protection.
Position the temperature probe in the 3-way valve on the internal coil, reverse water flow side, with a plastic collar. To increase the accuracy of the fluid
temperature measurement, isolate the probe and the 3-way valve (see wiring diagram below)
