Instructions for use

General information
The start up and automatic temperature setting is carried out
by means of the ambient thermostat, at 24 volts, specially
designed for these units.
Depending upon the model of your air conditioner, same will
be controlled by the corresponding thermostat. The thermo-
stat models may be: T-11 (one cooling phase and one
heating phase), T-12 (one cooling phase and two heating
p h a
T-22 (two cooling phases and two heating phases). The
instruction manual will allow you to become familiar with the
operation of any and all of these.
Ambient thermostat
The thermostat for the SOC air conditioners are designed
to give a correct ambient temperature control, and have all
necessary controls for start up, stopping, selection and
automatic temperature setting. It is equipped with a thermo-
metric indicator that permanently shows the ambient tem-
perature of the room being conditioned.
