Additional Controls (Micom models)
Additional controls can be seen after removing the front grille and the
option cover of the control box.
To remove the front grille, pull out the bottom at both the sides and then lift
up the grille as shown in the figure on the right.
And to install the front grille back to itʼs original position, place the tabs over
the top of the unit and push the bottom of the front grille until the clips snap
into place.
Now the additional controls are located behind the option cover of the con-
trol box. The standard settings are in the "OFF" position as shown in the
figure below. The authorized personnel has to check the switches and
ensure that the switches are in the desired position.
Here in the figure above the three Temperature limit switches ( Temperature Limit 1, Temperature Limit 2 and Temperature
Limit 3) can provide various temperature ranges of operation by means of different combinations of dip switches as shown
in the Table below. These temperature limits prevent overcooling and over heating, by limiting the lowest temperature for
cooling and by limiting the highest temperature for heating respectively, thereby reducing energy costs.
