Terminal Strip Pin - Carrier Aqua SNAP PLUS Manuel D'installation

Auxiliary accessories connection
Signal for requesting an External Heat Source or Dehumidification
Between PINS 4 and N of the terminal strip (see Fig. 17),
there is an output (1ph ~ 230V, 2A max) that can be
programmed using the remote User Comfort Interface
(see the control manual, Installation Menu code 106). The
output can be used to activate a Dehumidifier when the
measured relative humidity is higher than the pre-set value
(Installation Menu code 107).
Note: The following function is only active with the User
Comfort Interface installed.
External water circulator for 30AWH__X unit
Units without an integrated pump allow driving an external
one.

Note: The maximum total instantaneous current must be less than 3.5A. In the case of loads with higher absorbed current, it is
necessary to drive the loads with relays to be inserted between the power supply of the load itself andreg from the terminal strip.
10 30AW
Alternatively, the output can be programmed to provide an
activation signal for an external heat source (such as a gas
boiler). In this configuration, there is a provision for another
heat source on the water system that is activated, turning
the 30AW unit off, when the external temperature is lower
than the programmed threshold (Installation Menu code
148).
The signal (1ph ~ 230V, 2A max) is supplied between PINS
20 and N of the terminal strip (see fig. 17).
