Step 4 Ð Determine Controller Location Ð The ®nal step in the terminal selection and layout process is to decide where the controllers will be placed.

The temperature control zones in the building will be de- termined by the ®nal partition layout. Before the ®nal par- tition layout has been determined, you must install enough controllers to meet job requirement; the controllers can then be relocated when the tenant layout is ®nished.

One of the main features of Moduline controls is that con- troller locations can be changed quickly and easily at any time.

Another main feature of Moduline controls is that more than one unit can be controlled from a single thermostat. In large interior zones the ``master'' unit (the one with the ther- mostat) can be hooked up with control tubing to control sev- eral ``slaves''. Table 13 shows the maximum number of units that can be controlled by one controller.

*See Tables 6-8 for recommended combinations of units in air series.

²The 37HS1 unit wit h 5 x 7 size plenum is available with blank end only; mul- tiple units of this size would not be used on one control.

NOTE: The conditions stated in Table 9 must be included in evaluations for selecting the number of units in an air series.

GUIDELINES FOR CONTROLLER LOCATION

1.A master unit is mounted in the ceiling so that the air intake is on the end of the unit opposite the end with the control block and controller. (Fig. 26.)

2.A slave unit can receive air from either end of the unit. Either end can be the inlet, assuming the inlet collar is the same size as the connecting unit. At the same time, it is good practice to place the ``control'' end of a slave unit downstream as shown in Fig. 26. Should the slave unit be later converted to a master unit, the unit would be in its correct con®guration for control installation.

3.The volume controller for a single unit should be located on the end of the unit opposite the inlet end. (Fig. 27.)
